Great video Derek. And yes, I'm watching it on Christmas day! I always do a flue integrity test first on a service. I had 1 fail massively a few months ago, checked outside and the customer had propped a massive trampoline up on its side against the back of the house totally covering the flue terminal! All the best mate.
Great honest video , it just goes to show even the best can sometimes get it wrong, and it’s warming for us Engineers to hear that it can happen , sometimes as we get more experienced we don’t look for the obvious !
i had this exact fault on a job a couple of years ago. the guy had smashed the end of the flue terminal off with a set of ladders. On another job, after a big storm I was called to a locking out boiler, the wind had blown over their washing line and the clothes were blocking the flue. Not a wasted journey there as those electrodes were gonna cause that boiler to stop soon anyway i reckon. happy christmas to you and yours.
I admit I shy away from serving Worcester boilers but this was great Video, Give me an Ideal to fix any day, The amount of Engineers that don’t do a sweep test after changing gaskets😮 even the manufactures own service engineers don’t do it sometimes, I always do it but sometimes a gust of wind blows the & I have to do another one especially on a logic, I’ve done sweep tests on brand new logics & had temporary high readings then ok only to find loose nuts on the burner head, I told ideal & they don’t seem concerned 😣🤔 Brilliant videos as usual 👍
Hi Derek -- yes iv'e had the same problem on worcester's flue plume kit joint connection coming apart too -- it's not a really secure connection to stert wih -- that air intake looks close to that adjacent wall -- it can't be much more than the 600mm required ! at lest you gave the bolier some love and effection --- take care + all the best -- Jim ...
I was told gas pressure should ever be on the min in spec because the householder might turn on their oven, and the street at teatime might cause it to drop, then drop their gas below min required for safe operation? For Eg, if 16.5 is min, then the reading should be above 16.6 or fit a bigger gas supply pipe or range the max heating load down in settings?
I had a similar problem with a Worcester……the CO/CO2 ratio was very high……I had phoned the tech phone line, the verdict was the gas valve needed replacing……when I went to disconnect it and fit another, the rubber hose between it and the heat exchanger had a small split in it, which was causing the problem…..
Wouid have been good to video the gas valve adjustment to get the Co2 readings where you wanted would be interested next next time you get one. Cheers Good video hope you didn’t charge her 🙈🤣
Just seen this one Derek. We've all done something like that at some time. Belated Christmas greetings to you and your family, and have a happy New Year.
I’ve been through same problem And without changing any part i replaced the flue because some one squeezed the terminal end If you take the cover iff it works fine and the co incidentally it was same days near new year 😂
To be fair the fan sounded like it had faulty bearings and would eventually cause an issue or fail altogether and with case on, the resistance in the fan will increase slightly. It does however prove the necessity of a good all over visual before starting work. All the best!
😂😂 it happens to everyone, even to the most experienced ones. Once I got a call from a client because her boiler had the same problem, and after a long struggle from me , she says , - I don't now if its important but last week some guys went up to the roof to do some repairs ... I went to find my ladder , climbed up , and voilà! I found the cause in less than 30 seconds 😅 Joyeux Noël from Lorraine, France 🎅🎅
Unbelievable, we were always taught that as you are walking up to the property try and see if you can view the external flue and terminal, not after you have exchanged a lot of unwanted and expensive parts to the boiler that still never made it work correctly. It felt like you were just guessing what parts to fit plus you need to move out of the past and wear work safety gloves, a lot of sharp edges of metal inside that boiler (Health and Safety) (How much did you charge you Sister for all those parts that wasn’t really required…?)
@@GarryWinch all the parts were required and of course I didn’t charge her a penny as for gloves I like to feel what I am doing so not a chance will I wear gloves repairing a boiler.

You're a top fella Derek. 👊
Happy Christmas Derek and all the family. Enjoy your videos every time. All the best for next year.😂
Cheers Derek we live and learn 😊
Have a great Christmas and NY

Great job Derek...have a fantastic Christmas fella.
Have a great Christmas Derek to you and yours
Happy Christmas mate. Another nice video👌
Nice one as always. Merry Christmas!
It’s always helpful buddy, thanks for sharing
Nice detailed video mate. Have a great Christmas 🎊 🎉. I’m glad it took you 3 hours, now I don’t feel so slow 😂
Looks like it was due a service anyway happy Christmas Derek
Great video, i have done exactly the same 😂
Have a great Christmas and keep the videos coming.
Happy Christmas to you and family Derek

@@applanateearth586 correct but what if I tested for this or they only have the one gas appliance. I didn’t show all the tests I did.
I was shouting at the video all the way through “CHECK THE FLUE “ ha ha ha merry Xmas
Yep.
Works with the case off but not on, mmm 🤔🫣🙂
Merry Christmas Derek!
That gas pipe hose always needs replacing if it's the coiled type for the smooth one. the older type was prone to splitting
Day off and family rate😂 merry Christmas Derek

That’s interesting thank you
Nice one! Tightness test and flue check first.
We all do stuff like that sometimes…. Forgetting the basics
"good morning viewer" - there's more than one viewer., but we have a rota so there's always one of us watching around the clock
😂
I usually put some small washers behind the screws on them flues stops that problem

Cheers
Good video hope you didn’t charge her 🙈🤣
Worcester tell you to do your co/co2 with case off . They will increase slightly when case is fitted. And fI obviously with case on 😂. Nice vid 👍🏻
Hi TopKat what an amazing trick to change CO2 readings in less than 2 seconds 😅👏
How did you check the expansion vessel without draining the boiler?
@@mikewebster892 I did I just didn’t show it.
@ Merry Christmas to you and your family!

I’ve been through same problem

Good lad!! ✌️🥳
Expensive Job Derek
Hope You Get Paid

@ I know the feeling, It needed that good Service
Have a great Christmas
How is the tpi measuring 21% O2? I was always told 20.9%
@@Ian20232 because it guesses the 02
How to fix a noise fan. Put the cover back on 👍
well sorted derek like your videos all good content have a good christmas see ya in 2025
Did you make a donation to the Worcester Bosch blood bank ?

Sure it was the pallet and not the ladders putting up christmas lights?
@Stormin_Mike the neighbour blamed the plumber who had just done the new bathroom and put the pallet there 😂
@@tomkatgastraining Pointy fingers time...ha ha.😏😏😏
Happy Xmas
Never mind we've all been there...😆😁😗🤫

cant check the water pressure without draining the heating pressure. false reading on that pump...
Didn’t show everything I did but I can assure you that there was no water in that boiler when I checked the pressure
Done that once or twice 😂👌🏼
Those Worcester plume kit connections are shockingly bad……..

Safe to touch even when I go to toilet 😂
I’d get cage on that , terminal!
Every body has already said it.
those screws on that worcester have got to be one of the worst designed ways of removing a boiler casing .well over engineered
All that graft dude to find a flue disconnected damn bro have a merrier xmas you deserve it 😂
