Hello, thanks for a great video. 👍🏻 my pump is very warm is that normal?
Hi Pia, yes its a motor so it will get hot, if all the rads are hot all is well, thanks for asking George
Thanks. Course looks interesting...
It is very interesting all about how to adjust the boiler / system for higher efficiency and I teach how to find and fix faults. All Gas Safe & Registered sparks are welcome www.mrcombi.com/application-form/
all the best, George Staszak
great video - thanks
Thank you for your Wonderfull comment, take care, george👍
Hi,my parents have just had a new shower fitted on a gravity fed system,can they use a central heating pump I have spare to boost the pressure or does it have to be a shower pump?any help would be appreciated,thanks
Hi thanks for asking, no, it's really an agitator not for pushing/pumping water from A to B. You need a two channel, the cold water must come from the loft tank, the HW from a separate connection from the top of the cylinder. All pump firms will have lots of helpful advice. take care George Staszak 👍😃
Hello! Can anyone help me with my issue? Namely, from some reason, heating is not working, and I tried to check the pump, by unscrewing the cap as in this video (to try to start it manually by screwing the inside screw), but when I removed the cap on the pump, water started to come out in the stream. I closed it quickly, as pressure started to go down. Is it normal thing? Do I need to ignore the water stream and to try quickly to unscrew the screw inside the pump to check if it is jammed?
Hi Milan, thanks for asking, as the video shows that screw is only for venting, not for spinning the propeller. There are many reasons why the heating is OFF, programer / room stat fault, stuck in HW mode, pump Ohms test, best call a factory training engineer, regards George 🤩👍
Thanks George for prompt reply!
The pressure in the system was too low, and I did notice that. And once, it stopped to work. I added water in the system and increased the pressure, but it still does not heat...
That's one fault found, now you need to check the rest of the list in my last reply. George @@milanmitic5865
I also checked the pump now. I hear that it works (at least I think that was the sound). When I increased the speed of the pump (on the button), I could hear that the speed was changed. I think that pump is ok. Room thermostat is also ok, I checked. What could be next on the checklist? Sorry, I did not understand the abreviations you listed in your message...
Hi, my hot water pump is constantly on even though the hot water and CH is off. I changed the motorised valve but the issue remains. Any idea? Thank you
Dear kr173sh, Thanks for asking, who told you to change the diverter and how did you test it? If the pump runs in HW the stat is still calling, see my videos on HW and Diverter faults and how to test parts. 🤩👍
@@mrcombiBedford the plumber said the micro switch was sticking and to change the valve. It worked for 2 weeks but can to square one.
Very good, excellent, now call him back to fix it, he is very good👍@@kr173sh
@@mrcombiBedford should the water pump be on when you turn on hot water on the tap? (with the central heating off )
@@aixalexander5257 Hi Aix, I am not understanding your question "water pump" combies do not have water pumps. 🤔
Got an old standard Grundfos. Changed 6 radiators and flushed system. After about an hour of heating, the boiler cuts heating and the pump speeds up, creating a bit of a humming noise. Is this the boiler overheating? The thermostat doesn't indicate we are up to room temperature yet and radiators still hot (TRVs set to 18, as is the stat). Pump is quite hot to touch. Boiler temp is set to 55-60. Anything I can do to avoid it cutting out, e.g. pump speed, or do I need a new pump? Boiler is worcester/B and 4 years old (not a combi)
Dear Matt, thanks for asking, please follow the link at the end for more advice, ignore the training I have retired. The not so old 15-50/60 should be OK you did't say 50 or 60, 50 will be good enough, 60 would be noisy and hot, that always helps me. 6 rads you should have a mid position diverter as you have less than 13KW of rads. That and ALL systems need an AUTO by pass to dissipate "pump over run" which is your fault. Also I bet the refill was not F2 which is a requirement. Please use this link and see others about AUTO by pass. Hope that helps. ruclips.net/video/sDSQSKOixow/видео.html

Hello, what causes that buzz humming electrical noise, on a combi boiler.
Hi Eddie, humming is normally a motor not spinning as it should due to worn or not lubricated bearings. These new multi speed pumps and fans are most prone. Sometimes a PCB can send wrong volts also volts on Natural will cause this.
A simple test is a very long screwdriver put the handle end in the ear then CAREFULLY place the other pointed end on all parts that move, the loudest is often faulty replace with the latest version.
Thanks for asking, George Staszak
What does ICHS stand for in "GRUNDFOS UPS 15-50 ICHS" ?
Thanks for watching and asking, it's a code from G'Fos to say it's in the domestic range, ignore it, take care, George 👍
just had a new boiler and pump fitted. The whirring from the pump drives me nuts! Not sure what to do!?
Dear Shahira, thanks for asking, This should be covered by your minimum 2 year guarantee, call them back, any problems call Gas Safe 0800 408 5500 to report them do NOT take any excuses. Sounds like poor circulation and a lack of inhibitor. Compulsory get the water quality checked, take a foto of the result, 2: The external by pass is set correctly. Get the Gas Inspector to check everything, I bet there are more faults. Take Care. George Staszak 🤩👍
@@mrcombiBedford thank yiu so much for your reply. I really am very grateful you took the time out to advise me! I have just bought my house and the old boiler broke 4 months in 😔 I will contact the company who installed it (local guy installed a veissman for 3k) but the pump noise has a horrible high pitch whirring noise when you turn it om the 3rd setting. It is a bit more bearable on the 2nd setting but i can still it. The 1st is a bit quieter but too low too release enough heat. Will keep you updated!
@@mrcombiBedford which gas inspector do i use please?
The Gas Safe👍@@Sherry78
@@mrcombiBedford sorry to ask again but do they charge? 3k was expensive enough 😕
Hi, last week my boiler lost pressure and then made trickling water sounds. I new it didn’t sound right so I turned it off and called plumber. No lockout light on. He serviced boiler and ordered a replacement for the red tank on the right (Worcester boiler heat slave 26 32) he said that was full of water and should be full of air. So he came back and fitted red tank. Yesterday I put the hot water on for washing up as I had more than normal (usually boil a kettle for washing up) I had hot water. Today I notice the pressure had gone right back down to zero! Do you know what the problem could be? I have just turned valves to replace pressure and have hot water on now. Turn tap on boiler fires up and after 30/40 seconds I get hot water though the flow decreased so I turned the tap more. I ask as my husband passed a few months ago so looking for a second opinion as not wanting to go and replace more parts unnecessarily. Thank you in advance for your reply.
Dear Irene, thanks for asking, I have found your boiler as an oil 32KW (big system) about 2005? could be well past its date. 1st the cold fill and the 12ltr red vessel should both be 1.4bar and rise to a max. 1.6 bar, I bet it goes higher thus an external 18ltr should be fitted also at 1.4bar. It's a pity the plumber did not empty and test the diaphragm. Page 18 of the install book recommends TRVs everywhere with an auto byBass, is that so? Check if the new one is 12ltrs Because you have a small mid position valve the pressure will rise a lot. Refill to 1.4 bar and switch the CH on for 15 mins, does it go above 1.6bar? If yes fit as above. A new digital pump would help.👍 Hope that helps, George staszak
@@mrcombiBedford Thank you for your prompt reply, I will speak to plumber. Thank you.
@@ireneinwales glad to help
Wat if I just remove the back screw an blow a load of silicon spray in? I'd prefer not to empty the system.
Hi Ronald, thanks for asking, the problem then is when you remove the screw high or low pressure water will shoot out (not safe) You don't need to drain just depressure. If you just want to lub. the pump front use silicon PASTE quickly refit the screw. If the pump is faulty replace with latest version. regards, George Staszak
Hi ,thank you for sharing video- keston combi boiler C30 with Grundfos upm3 pump, makes once a day hugh vibration noise - when warm water taps are running- if we stop the taps... the vibration seizes - and again for day or two no huge vibrational noises... other than this combi boiler works normal....any advice in advance... is much appreciated.
Hi Thanks for asking, could be the tap jumper, when I get noises I get a long screwdriver put the handle in my ear then pointer bit all over the place. You will soon find the loudest part, replace. Don't forget the diverter valve. Hope that helps. George 🙏
@@mrcombiBedfordThank you.
If the pump was jammed would there be a loud tapping sound? I have hot water but no heating. It's a f&e condensing boiler. Thanks😊
Hi Martha, if its stopped cannot make a sound but will get so hot it will burn out, do NOT touch the centre screw, no worries turn off the power, find which pump is now recommended, drain and flush fit pump, fill as video F2 etc. take care, george👍
@@mrcombiBedford Thanks George, I checked the pump and it's running, not hot, the tapping is coming from further along where there is a square metal box. Time to call the engineer I think.
@@marthacunningham2028 I alway recommend either the boiler firm or a local hero on their web site.take care, george
IT s the valve motor actuator you need to replace, it’s around 20£ on eBay..I had the same problem..hot water but not heating…
@@nicolaeradu4737 If the pump works for HW its OK, check diverter valve, check coil should be about 22Ohms, to check the pump do NOT turn the venting screw, drain down remove the head to turn impeller, NOTE you can only replace with Grundfos USP 3 see my video, not a £20 eBay with will fail, flush fill with F2
Hope that helps, George staszak👍
What about a pump that continues to run even with the hot water cylinder calling for heat. 3 port valve fitted. System was working ok, but now has this issue.
Thanks for asking, the pump should run in demand and then pump over-run ( if fitted ) will start until boiler temp is 59C. If continues then see stat or PCB which ever controls O/heat.regards George Staszak 😀
@@mrcombiBedford are you advising room stat. What about 3 port. Could it be that.
@@makingtheweb6620 You said it's in HW mode? Testing the diverter is easy, done vids on that, I can't see that making a pump run
@@mrcombiBedford I know the customer said that the cylinder stat wasn't clicking and sounds like it could be at fault. He has a spare one in the package in loft, old one by the looks. I will get a new one and try to do same wiring as the one that's going to be taken off. I just see you do course on wiring. Not my strongest point, but would be interested to visit to attend. Cheers
@@makingtheweb6620 Hi, I have retired the train centre has now closed, have a look at the video Heating faults 2, can't include attachments here send me an email to info@mrcombi.com
My pump is leaking, can i save it in any ways?
Hi Amir, not really, depending on your system a UPS3 does most, get the Grundfos APP to find the correct replacement, have a look at my video one UPS3, that should do it,
good luck, George 👍
how about, pump makes litteraly 0 noise? and still not working, not even the pipe hot water aint working which i supose does not relly on pump... wtf is wrong with that stupid thing...
It starts burning, it starts heating water, then you can hear the switch and immediately shuts it down, and the 'sand clock' diode keeps blinking
Hi Nikola, Pumps and heating systems must NOT be tested in HW mode only in Heating, because it tests the diverter valve has moved and many boilers do not use the pump in HW. If the heating is OK then the FLOW pipe gets hotter, if not either call a breakdown engineer or factory Tech. Dept. All the best, George Staszak 👍
