Just sat down to watch this series. Customer seemed quite knowledgable and a nice chap.👍😀 Fault finding is fun.😉
Can be, this one wasn't :-)
I'm a Worcester man when it comes to boilers and repairing them... But this was interesting to watching a 40 year old boiler great video mate keep them coming love watching your videos
Glad you enjoyed it. Worcester are ok but they are difficult to work on. The compact is a pain too. Soft metal bolts on that one.
@@HeatingGeek I will agree with you on that... I always dread the prv change on the I junior and si series.. But the newer models are looking promising as in for the service and repair engineers
You are a very brave man. Respect. I was working on these boilers in the 80s both installing and repairing and have just thrown out a unused wax capsule and diverter valve, an expansion vessel, the electric box with all three boards and a load of other obsolete boiler parts ie leblanc, Vokera fan assisted open flue boiler. Garage got cleared due to isolating. These old boiler if understood, ie the sequence of operation are not as bad as they look. I replaced my vokera open flue boiler last September and only because the main heat exchanger was so fin due to age and I never had another one. It was a fantastic boiler giving 35 years of service and apart from servicing, changing diaphragms , one pump and an external expansion vessel. It had on other issues. The last since 18 I worked on was two years ago. Thought they had all gone.
This boiler really stressed me. Not because of the boiler... Because I didn't understand it correctly. I should of done a little reading before my second visit. I should also have linked out the microswitch.
WOW -- I remember the boilers from the late 70s -- i'm sure they were the first combis in britain at the time -- think we used to be dealing with ideal + glow worm simple stat + gas valve free standing boilers -- then our German friends sprung this monster upon us -- like a glider to concord eh --you are a top gas engineer i love your videos -- im 64 almost at retirement age now so i try +make sure my 350 regular customers boilers are serviced every year -- i'm still fitting the odd boiler thoe --+ yes the vaillant eco tecs are used quite often -- but recently i've used a few vokera easi heats coz of the price -- half as much as a £1300 eco tec with a better guaranteee too take cae JIM
Great stuff heatinggeek keep on good work mate pleasure to watch your videos 👍👍
Thanks 👍. I will keep it up. Work is starting to come in again so..... Time may be an issue
I'm an apprentice sparky but obviously have to know about heating system wiring, but find all your videos satisfying you certainly know your stuff
Thanks :-) My brother is a sparks and I would if I could.
Never worked on one of these before good to see inside the guts of it
Looking forward to part 2 chief!
Im not. Editing it at the moment... I completely fall to bits on it. :-)
salute you for working on that boiler fella, was repairing them 20 years ago, and haven't seen one since thankfully lol
Great boiler. I wish I spent a bit more time understanding the thing before I started.
Epic video Ollie 🔥, what a beast of a boiler 👍. No plastic at all, built like a tank. Your fix it mate, your are the boss man 👊. Looking forward to part 2.🌟
Glad you enjoyed it. As I said on insta. Next part is massive...
Absolutely love your work Oliver, definitely this is not for the faint hearted, always like watching your videos gives us all free knowledge and i hope if you reading this it keeps you motivated to upload videos for us i know it takes lots of effort thats why i always click the like button before even watching thats the least I can do
Thank you so much 😀. The next video is a real struggle to edit. Im working on it now. :( Very stressful to watch back. :-)
Brilliant video 👍 look forward to part 2😁
Coming soon! Editing it now.
Amazing job mate, classic boiler - wish I was there 👏🏽
I should of linked the microswitch to find the other issues..
Sine 18, I remember installing and repairing these back in 84-85. Diff pipes were common for blocking and not actuating the servo. Looks like 90% of the boiler is working and water valve leak and microswitch are the issue. Your right a couple of more tests would have gave you peace of mind. Looking forward to part 2 and the outcome.
If only part 2 was going to have the outcome. :-) It is being edited this week. :-)
Firstly let me say your videos are probably in my eyes the best fault repairs ( explanation, camera views , everything) available.. keep up the great work. Do u ever come accross jobs that u struggle and apart from manu tech helplines do u have engineers / friends that u call upon for advice or have u always managed solo.?
Thanks
I do call people for help sometimes. Not too often though. :-)
Blimey, I had a 32 year old Worcester open flued combi I took out last year. You done well there 👍
Its not fixed yet..:-) Not on the next visit either.
Brilliant mate. I wouldn't have a clue on something that old
I didn't. Trust me
Another interesting one...looking forward for the next one. Thanks!
More to come! Editing it now. :-)
Awesome 👍 repaired,Looking forward to part 2 , i 'm sure you can fix it
It was the most stressful job in a couple of years. I didn't want to fail... I should of linked the microswitch though. :-)
Being in my early 50's I've worked on many of these over the years, Not too bad to work on once you're familiar with them, and surprisingly you can still get some parts for them through Parts Centre!!
I was not as versed with this boiler as I thought. I should of linked the microswitch out and found the extra issues....
That would have taken me well outside my comfort zone, don’t mind old school and I do like trying to fix the but I’d have spent longer trying to find and understand an MI than I bet you’ve spent on that all in. Nice to watch, looking forward to pt2. Nice vid
Its not fixed yet. (the boiler may be) Part 2 will show how far out I was. I should have linked out the switch and seen the boiler run. ;-)
Respect my man ....,
most of us would turned away at first glance for many reasons.. which you r well aware of..
I do like old boilers though. Made sooooo well. :-)
You can clearly see once upon the time manufacturers tried their best to make good boilers but as soon as efficiency came into the game it went down hill...
@@hadjarramouche9984 This is the boiler that started Vaillants reputation in the UK.
Wow impressed with the engineering for its age, a boiler that's worth trying to fix!
Exactly :-)
I think you are one of the best in the world not just in the UK ... and I love the KISS slogan you use top man 👊🏽
Thanks :-) I really struggled on this one. I'm editing the next video now. What a mess.
Love your videos
Thanks :-)
I'm still running a Glowworm 45 BBU installed in 1988, coupled to a slightly later Glowworm Homeglow fire front, I believe was installed in the mid 90s. I moved in my house in 2001 and these were here when I moved in. Its now almost 20 years later, and in all that time the boiler has never caused an issue. I clean the lint filter behind the gas valve every year and make sure all dust is vacuumed out as it builds up quite a lot, and I have had to replace the circulator and mid position valve, plus tank stat and controller in the time I have lived here, but the boiler is the art of simplicity, no PCB's, no complexities, and it is reliable, but being open flue is not efficient. I feel that the cost of replaceing this boiler with all the pipework alterations it would need (its a terraced 1900 house) would cost thousands, and modern boilers are nowhere near as reliable as the old stuff. Had I had an engineer out to service my boiler, he would likely condemn it, and try to flog me a new boiler, so as long as the Glow worm keeps working, I will leave it in. Old stuff is not always bad, and too many old boilers I feel are ripped out just because people feel, oh, its old, so it must be no good. I do have CO alarm in the room and I regularly check it burns with a blue flame, so I feel its safe enough to run. Who knows, it may even be here when its 40 years old, in which time other people may have had 4 boiler replacements with modern stuff that just doesnt last longer than 10 - 15 years.
Your absolutely correct. The only thing that puts me off BBUs is the safety implications if things go wrong. Also the customer often don't understand why it costs more to service a BBU. Its simply a time thing. No one wants to rush a BBU.
I love your ethic of fixing it first before replacing ... I hate waste and would do the same .. love your vids .. also reminds of when I used to live in London .. I am in Swansea now waiting to finish my gas safe after lock down is done
I don't replace boilers. My back knees and shoulder are screwed from doing it (and crashing on a pedal bike). Breakdowns are a better side of the industry a lot of the time. Some times you can be working at a difficult angle but that's about it. :-)
@@HeatingGeek Yeah, Same, my back is destroyed from looking into floors ... i am working towards breakdowns like your doing, you are insprirational mate
@@moulesanctuary Much easer on the body. No so much the mind though. :-)
Great to see the inside of such an old combi. Also, really helpful to see how you work through this step by step, identifying and fixing each fault. Will you be wearing the same groovy PJ bottoms in Part 2?😊
Glad you enjoyed it! This job wasn't my finest tbh. I was under prepared. Part 2 is done and will be uploaded tomorrow.
That's a beast of a boiler. Love it
It is a beast. :-)
Unbelievable, can’t imagine where u would get pj bottoms like that from😂. Lookin 4ward 2part 2👍
Tell me about it. :-)
Beautiful boilers these. I do get a bit of the vapours when I get a broken one though.
I did on this one... Completely broke me on the next visit.
That boiler and e39 are classics 🙌
Yes they are! Not my e39 though. :-(
What a beautiful piece of engineering, one of the first combis I installed back in 81 or 82. Amazing!!! Gawd, that was a step in the dark back in the day!! I remember the old boy from the Gas Board was shocked by it; ‘These boilers will never catch on’.......😂😂😂😂
I don’t think we even fitted a filling loop, don’t think we knew what it was! The MI’s too were a work of art.
Very poor HW flow rate, but German Engineering when it was proper engineering. These PCBs, relays etc, just quality & built to last.
Was it the original thermocouple mate??
I think I’d of linked out these microswitches & tried it. Loving it mate, thanks for sharing👍👍
I couldn't tell if it was the original thermocouple. It Looks it. Still had the braiding on it. I messed this visit up and it cost me loads of time on the next visit. :-(
But I have learned this boiler inside and out now. :-)
Because I see them every day.... :-)
HeatingGeek 😂😂 I’m looking forward to the next one Ollie👍
@@TheDickPuller I have been editing the next one. Absolute shambles... :-)
Still have the training manual for this boiler ,one of the first training course I went on in the 80s . Still have one of these boilers on my book and still working fine famous last words
Famous last words indeed. :-) I wasn't born :-)
Looks like a Britony 11T hot water exchanger, Always interesting fella!
Thanks :-)
Thank god for these videos to keep my brain ticking along. I would of linked out micrswitch to see if any more issues after that.
Spot on. :-)
Hope your well mate, keep up the good work on the videos 👍
i have micros like that laying about for years, i collect everything.lol. good vid again. looking forward to oscilloscope video.
It will be a while for that video. I have everything except the time. :-)
@@HeatingGeek yeh i understand, you have to create a subject to film about also, i hesitated buying one of those pcb oscilloscopes! Are they any good? Can you fault find of boiler electro=nics with one easily? Where did you get the idea from?
Amazing that it still had the paper electric schematics, inside the controls box, very handy. 👍
I know, right? It was not as handy as you might think. :-) Next episode being edited this week. :-)
The main gas heat exchanger is based on the types in multi-point water heaters of the time.
Chaffoteaux had a CH boiler range based on their existing water heater range. They were literally their existing single-point and multi-point water heaters slightly adapted. The pressure of an external pump activated the diaphragm, as in the old Ascots, to fire the burner. Instead of fresh water running though, it was system (rad) water. One was 25,000 Btu (7.3 kW), enough for a flat or small house, based on an over-sink water heater being natural draft conventional flue. A was a tiny thing. The large units based on Multi-points were normal balanced flue jobs. They did not sell many of them. Crud in the CH system would block up hydraulic valves - they needed filters - so were not a big hit. They were simple and cheap though.
The earliest Chaff I remember was the brittany combi 2T. I loved freeing of the plastic diverter. :-)
I’ve actually worked on one of these many moons ago, unreal piece of engineering
Brillant boiler. I learned a lot from this job. I should of read up on this before I started.
T3w sine was the first combi I ever saw about a year after yours was made................... Back in the day you made your own fill loop from a pair of washing machine valve, hose and a 15mm check valve.
They were very little trouble compared to the modern kit..............
Can't even remember when I last saw one.
Its a shame really. :-) I have to knowledge to fix these boilers now. :-)
Sick vid. Can’t wait till part 2. U could of manually made the switch urself b4 u ordered. At the same time the switch was clearly burnt out. Really enjoyed watching this. So entertaining!
Good call! Thats the mistake I made. What a pig the next visit was. :-)
HeatingGeek
Clucking for the next vid. Never seen that boiler. Brilliant engineering.
@@nathanielthomas7995 The next video is going to be killer to edit. :-)
HeatingGeek I’m having withdrawal symptoms. Cold sweats 🤯🥶🤮🤯🥶🤮.
I want to ask if u fixed it but I don’t want spoil the vid.
great videos as always, could you of linked the switch out to prove thanks
Exactly. :-) Then I would of found the many other problems...
Great video 👌 Brings back some memories 😀.. Get yourself some alligator/crocodile clips if you haven't already 😉
I have them..... I should of used them.... I messed this bit up and It cost me on the next visit.
I ripped one of these out last year , was hard work just trying to get it off the wall, let alone fixing it😂
You made me LOL. This nearly broke me. Literally wasn't sure if I wanted to fix it anymore. I should have linked out the switch....
First time I've seen a Sine 18, worked on hundreds of Combi-compacts and Thermocompacts though, and that wasn't yesterday ;)
Yeah I haven't had very much to do with them. It shows on the next video....
I was totally renovating an very old 3 story weavers cottage listed building in 1980. I knew I'd get £6500 grant when I made an offer of £6501 for it, this meant I got the house for £1. As I progressed with the work I realised I'd have a bit of money spare. As a joiner I realised I'd have to get a Plumber to install the boiler etc. I studied the boiler option and liked this new Vaillant combi boiler However it was £995 but what the hell I bought one. My plumber mate John wasn't impressed with my choice saying "these are a flash in the pan they will never catch on". He'd piped every thing up but when he'd got to piping the boiler up he was scratching his head nearly all day. As a fellow tradesman I left him to it until he told me that they'd sent the wrong pipework kit. When I looked at it I realised that he was looking at the drawings as if they were building drawings when in fact they were engineering drawings. He wasn't having any of it and walked off the job. So the first thing I did was get a book out of the library on gas fitting. I soon realised he had under gassed it 1/2 " instead of 3/4". Very slowly with the book to hand I got it all up and working, and what a cracking bit of kit it was. That's how I started to be a gas engineer, I even ended up doing the gas work for John the plumber. I took one out last year still working at 39 years old, the client was worried about getting parts. I did say that the Baxi Duo-tec wouldn't last 39 years.
Bet the Sine 18 would still be going strong. Have you still got the cottage? I'll give you £13003 (more than double your money) :-). Are you glad you became a gas man?
@@HeatingGeek thanks for your comments. No I moved the house on after 5 years (expanding family). When I drive past the house has had very little or nothing done since. I still enjoy working as a gas engineer at 69 years old. It does make me wonder however how little some gas fitters understand about the workings of the units they are working on. A lot seem just to say "sorry love but the boiler is beyond repair, you need a new one that we can fit". Its funny though, I'm seen as the old hand that is the font of all knowledge. When I only got into the job by accident.
@@tonygreenbank8611 They are also brainwashed that a boiler will pay for itself after a few years because it's more efficient.... The fact the boiler will be less reliable over its lifetime and cost a lot more to fix each time it fails is lost on them too. I hope I can eventually change a few engineers views on this stuff. :-)
Fantastic
Thank you so much 😀
If you have a problem... if no one else can help... and if you can find him... maybe you can hire... The Heating-Geek...
You're definitely more like a Murdock :-)
Great work bro.
Ha, please done give me anymore of these.... Nearly cried. :-)
Yes, I have worked on three of those. One I was able to fix as it was 'o' rings and fibre washers, that I had in vanstock, but the last two, I had to condemn, because, parts were no longer available from Suppliers, and Vaillant said that it was too old for them to support, but they looked, very well built and very well engineered, but this is old technology. Not criticizing , as there are Glowworm Spacesavers, and Hideaways, as well as Baxi Bermudas etc etc out there! dx
People become attached to their boilers though. I thought this was going to a simple fix but i should have linked the microswitch out to see if everything else worked......:-)
one check you could of done was to short out the offending switch and see if it sprung to life ,but as you had found several other things and solved them time starts to add up! looking forward to part 2
Thats it. Exactly what I should of done.....
It has a bubble DHW heat exchanger, not a plate. A spiral tube in a canister. The micro-switches looks like an easily available stock items from electronics shops.
About 4 years ago in the Lake District I came across a large floor mounted Worcester combi that was immaculate, that must have been a late 70s model. The first combi sold in the UK was a floor mounted Worcester in 1972. They have very soft wonderful water there as well.
I called it a Plate to keep it simple for new engineers. :-) I messed this up by not linking out the microswitches and seeing what happened.
Phwoar! Revealing the pair of DHW microswitches was better than watching Under Seige 😁
:-) :-) Ok you made me LOL. What a pair. :-)
Ollie so how's you new idea developing with setting up training centre ? Is that still a consideration or you've given that all up due to covid and what not?
Im trying...... :-)
Those are bog standard microswitches used on loads of different things apart from boilers. They're used on a lot of electric showers and even on electric fork lift trucks, I used to keep a stock of them as they come in handy for all sorts of things and they're all exactly the same. You can get them from RS or the internet as long as you look for the switch and not for the boiler part which they will say is obsolete. When removing old electric showers I always used to strip them down and save the microswitches (usually at least 2 in a shower) as they get you out of the poo on jobs like this.
I have a load of them too. The outside the box method would be to build a new part with the spares I have. :-) It didn't come to that though. :-) I should of linked them out though. :-)
Could you have linked out the switch to see if the boiler fired? Or would this have caused any other damage?
I should of done exactly that. :-)
Nice bit of fault finding . It's always a bit tricky . Link out the micro switches first to see if this sorts out the problem .
Exactly what I didn't dooooo. I messed this visit up by not going further with it.
Looks like something NASA built! Beautiful
It does and it works great when It had been looked after. :-)
Did you not bridge out switch and confirm hot water worked great video but when is part 2
Part 2 is in the editing software. :-) I should of bridged out the switch...
sine 18 the best combi ever made.
I like the next one. :-)
T3W! Used to have dozens of these on our books ! We have recently replaced the last one we had 😩 Needed a wax capsule but couldn’t get one. 35 years old ! Absolute tanks these were ! This kind of quality does not exist anymore. Same with the VCW.
I agree. These are still brilliant boilers and If we can keep them going we should. :-)
I had a new Vaillant LPG combi in my first house in 1990. It resembled a jet engine inside and even their own engineer was scared of it, used to pop the front casing door open when the heating fired up in a morning.
:-) I wish I knew what one you had. :-) I bet it was the first ecomax. :-)
HeatingGeek I will try and find a picture of it.
It is very clean inside, surprisingly clean actually. I have to say that combis that old in some cases can't even be turned on again after service and usually get a death sentence if parts are not available. So if you get it up and running you've done a 1st class job!
If..... Thats the correct word. The next visit was difficult to say the least...
@@HeatingGeekhi where about your from pal
@@joeflynn6286 Hertfordshire, Or Ireland depending what you mean. :-)
From an electricians point of view, I certainly would of confirmed that the switches were in fact at fault. Simply by testing for continuity on the micro switches, although it does look like they’ve seen their days!
Hope it fixes it for the customer!
Yeah... A simple thing to do and I didn't. The switch was burned out and was faulty. I didn't link it out and see what the boiler would do next.
Hi would it be possible to temporarily bypass the faulty microswitch to see if boiler works. There may be more poroblems further down the line of doom. Most customers do not realise this and will think you have identified the problem.
Exactly. I wasn't thinking. I didn't think about it. I was so happy to see an obvious fault I forgot the basics.
Classic boiler solid
Yep. :-)
great video. I ask first customers about last service time . That customer is in 99% off all . tHEY ALWAYS SAY yes we service boiler or my fever, Boiler was runing perfect until now
Yeah customers can be cheeky. 🤣
Yeah could have linked the micro switch out to see if it ran...cool boiler though. Don’t think I would have got that far with it 😅
OMG don't watch the next one then.... :-) I fall to bits in it. I should of linked the microswitch though.
In USA we have tons of old natural draft low efficiency boilers. Have 2 from 1940's, 6 from 1950's, 30 some from the 1960's. Tons from 1970's and so forth. They are not efficient, but just keep going and going. No plastic on those things!
Yep. TANKS. Customers grow attached to them. :-)
Proper engineering
Thanks :-)
Should of shorted the micro swithch to see if it worked. Again thanks so so much for this vid Love the shorts lol
You're welcome! I should of linked the switch.... I have no idea why I didn't. Massive mistake. ;-(
TOP MAN !!!!!!!!!!!!!!!!!!!!!!!!!
I should of linked the microswitch out on this one. 😁
BTW as an amateur I'd I override that micro switch to rule out anything else mainly the PCBS and see if boiler fires up on demand
You would have done the right thing. :-) What a simple think to do.... And I didn't. :-(
@@HeatingGeek
Great, I'll be booking up first available slot !
Fitted the first of many in 1978 said nothing about a feel loop ! so called Vaillant they sent there rep out when he arrived I ask him how to fill the htg up and he had no idea, nothing in the instructions so he called Germany and they explained to us about the fill loop, to make a feel loop we had to fit two 15mm stopcocks we then fitted the controls one room thermostat and a Randell 103 time clock and it worked like a dream happy days i am still fitting Vaillants to this day
Yep they were all fitted with stopcocks or washing machine valves. :-) Old school. :-)
Punter was definitely having a crack at it himself. 😁😁😁
Hi Dan!
DIYnot blast from the past!
Im not too sure. :-)
Hi Ming, hope you're well?
@@YagiChanDan I'm here too lads. Hows it going?
There is a good chance that Adlink in Alperton HA0 1JQ will have your micro switch
The job is long done and they didn't. :-) I call them in the van that day.
Should have bridged out the switch. Obviously realised that when you got home. All been there 👍
Exactly that. I sat at home and It just popped into my head...
I think you only concentrated on the main issue. I would of also switch the central heating on as well to see if that works so that i scale down on what to really focus on. Then start from scratch TT, standing pressure at the meter and so on. Then try linking out micro switch etc... 👍🏼
The call out was for "No Hot Water". but you are absolutely right. :-)
@@HeatingGeek I'm glad you said that, now this will keep me thinking. Thanks for videos like these 👍🏼
@@mrsayef1059 No problem. Life :-)
Mini vessels come with some older Worcester’s too but still leaked lol
:-) I forgot I left that in there. :-)
When I was training the UNofficial mantra was "If in doubt, bridge it out"
Old school. :-)
old boy has been messing with it!!!!
Maybe. Im not sure though. :-)
1980 must be one of the very first combis installed in the UK ever! Before Trident Close even! And bloody hell the really old DHW heat exchanger (not the bake lite type)
Old. I should of read up on it before I started.... Saved me a load of time on the next visit.
It was a beautiful piece of kit. Way ahead of its time and built like a brick sh*t house. And then we dumbed it all down with the TURBOmax - tried to cut corners with the diverter valve and then shit happened for a year or two. A friggin nightmare but a good crowd to work for.
@@MKTbygmester The second turbomax was a beauty. I like the combi compact too. :-)
for those sort of parts you could use RS components most microswitches are standard size there are other places one in essex but i cant think of the name at the moment ! an age thing lol
I have microswitches in my unit. I got the part without too much difficulty :-)
HeatingGeek looking forward to see the next part I expect it will not be that simple!
there is a model before this one which is open flue i used to work on these models
I have seen the OF model but never had to work on one. I didn't know very much about this boiler when I walked into this one. :-)
The old stuff last much longer then what's out today, you'd probably have seen more of them about but more then likely engineers who couldn't work out what's wrong with them just ripped them out and put a new boiler up instead.
Thats the way it works. Cant fix it so say it needs a new one.
Did you try bridging the switches to prove they were faulty?
They were burned out. the plastic had melted away. The switches were gone but I didn't bridge them out to check for further issues...:-)
Sine 18 and vcw 242’s are the best combis ever made Barr non !!
They're certainly amazing engineering, but too complex. Reckon the Turbomax Plus is the best because it's still quality engineering, but easily fixable and tough as old boots. Sine is interesting, but who would want to own one now? The Turbomax will still be going a long time beause everything is easily undertood and easily replaceable.
I like the turbomax plus and the combicompact. I like all the Vaillant Combis but the combicompact is a great boiler.
I have a turbomax plus for my house but I would happily fit a Sine 18 in a holiday home where It didn't have to be lit all year round. :-)
Are WMI still in busines for boiler parts ?
WOW. Must be. I was there a couple of years ago. I don't know. Blast from the past. How did you know, I would know them?
@@HeatingGeek If you remember I was the guy from Barnet that subbed for T.A Horn wiring up systems and used WMI myself . And with you being Barnet bassed I knewyou must have used them at sometime
That's it. 👍 I knew it would be TA Horn.
99% of engineers would just fit new boiler but if it can be repaired then why bother. Good video mate
It might get fixed... :-)
Talk about engineers, i've had customers insist on a new boiler because of something like that!
Agreed.. great vid 👍
A 40 year old boiler would be about 60% efficient. A modern boiler would be 90%+ efficient, taking into consideration the cost of fixing this plus the inefficiency, a replacement boiler would be the better option with the customer recouping the costs within 8 years.
@@kryptoniteee 65% efficient. Also, this customer will not touch this boiler for the next 10 years. Probably won't even service it. Also, the environmental impact of this boiler was in the manufacture of it like a new one. The new boiler will not make 8 years without needing expensive parts replaced. The cost of repair spread across the lifetime of the appliance makes it worthwhile. The new boiler in 10 years will be on its last legs and have had a few parts replaced which make more costly to the consumer and the environment. :-)
Brilliant these early combis do you remember the myson midas work of art, over engineered or built to last was the debate, think the answer is clear
Could you have temporarily wired out the micro switch to check thats all it was maybe,
great to see one of these again
I should of linked it out. So much more wrong with the boiler....
myson midas with the TWO pumps?
Link it out
yep.. But I didn't. :-) Fail.
40 years old ! you would have needed to fit at least 4 of these condensing boilers ( at least ) in that time,having said that your a brave man to even attempt to fix it . The Germans do have a habit of overengineering things . Surprised the pilot did not blow out all the time with the case so badly fitted .Link out the micro switch to prove it one way or the other! If they are a standard microswitch and they will come out of the assembly you might get them at RS components or a similar factor. If the full part is not available.
I have the microswitches in my lock up. :-) Not for this boiler but could be made to work. :-) I should of linked it out and I would of found the other issues. :-)
We had one of these installed in 1985 and until last year all it had replaced was a pump and a diaphragm. At the service last year it needed a waxstat which i had to source for the engineer. at the same time i bought water and gas valves and had the engineer put them in(he thought i was mad). Will see me out
Yes it will. No offence and I hope you are of the vintage variety. :-) Brillant boilers. Very stressful to fix though.
@@HeatingGeek Lol, i am nearly vintage and it helps the young lads that come to service it that i have the original manual that came with the boiler for settings etc
@@alanfenwick3914 I should of read the manual tbh. Would have saved me a load of time on the second visit. :-)
Why didn't you take the microswitch apart to see what was going on?
Because it had caught fire and melted. Look at the photo of it. :-) I should have linked it out.
@@HeatingGeek Ar a guess, without checking, that would be a jellybean off the shelf part microswitch. Have you got a part number?. Check RS Online, Digikey, Farnell etc (even ebay). Probably a couple of quid.
They are so easy to repair, repaired hundreds, u can see , it will probably be the little rocker switch rite in front off u probably sencing tube blocked
I should of linked out the microswitch and I would of found many other things...
Omg what are you doing to us 😂
What am I doing to me. :-) The next visit was a nightmare... :-)
come on hurry up, wheres part two? lmao.... would you have bridged the microswitch to check it was faulty? Great video as always.
Im editing it. Massive though.
You could of linked the doofer to the thingamabob, to see if the Whatchamacallit energised.......................Simples 👍
You are completely correct. Simples :-)
I occasionally get that part I think is going to fix that boiler, knowing in the back of my mind on the drive there it’s not the right part 😂😭
I knew I had messed this up later when I got home...
Why don't you set up a Training Centre Oliver, you'd make a fortune out of it !
Im trying :-)
Defo would have linked that m/s out for proof. Easy from the armchair! 😉
Masive FAIL on my part.
