I was panicking after saw f75 error and the boiler stopped working on a cold Saturday. After watching this video, I managed to reboot the boiler and is now temporarily fixed! Thank you for saving my life 😊
Thank you so much, sir. It's 4am and I needed to shower but I was dismayed to discover that there was no hot water. Thanks to your simple but comprehensive video i was able to fix the pressure sensor and get the hot water running again. God bless you.
Huge thank you for this video! I was seconds away from calling an engineer out and paying a hefty fee but this video was so informative and easy to follow!
Worth noting that if the boiler gives this error after the entire system was drained and filled up again, that you need to open up the boiler, and twist the tiny gray cap on top of the automatic bleed valve. This will purge the little bit of air that is stuck in the boiler itself, instantly fixing the issue.
My boiler (vailliant) gives always f75 each time I need to add little bit of pressure and it's OK. There are no leaks and the pressure vessel is recently externally installed. The pressure on the display and gauge is also about the same. The pump is also working I do not what the problem be could it be pressure sensor?
I got the f75 but my electronic reader says 3.6 bars while the little dial shows that’s its so low that’s it’s gone below the grey bar. Do I still try opening the tap?
But if sludge is apparent which is possible and usual, then the sensing aperture in the pressure sensor will become blocked leading to to the F75 error code. This will mean cleaning out the system with Fernox F3.
Hi There we've has our landlords Barnet Homes attend around 16 times now due to central heating hot water problems. the pressure has gone down 5 times now since 4th November 2023 showing F75 could you kindly give me some advise please as Barnet Homes operatives have NO clue in what they are doing. even their Emergency out of hours just keep refilling the boiler. With Pressing on the - it states 1.0 bar so its one of four things that could be faulty on the system.
There is a leak in the radiator circuit if the pressure goes down. Use Fernox leak sealer, if there are no obvious leaks around the radiator circuit, or inside the boiler. The Pressure Relief Valve, which has a discharge pipe going outdoors, could also be leaking, but that will leave stains on the wall below it. The PRV has a red handle on it, behind the electronics box.
My boiler's problem is no error code but the Hot water generation symbol disappeared from the bottom left corner. can you tell me the possible reason please. It is a pity I am far away from you. My boiler is ecoTEC 624. Thanks.
Why would there be no pressure in the boiler (internal gauge reading zero)? Surely you need to sort that out before topping up and re-pressurising the system.
Si pusieras subtítulos en español tendrías mucha más audiencia. No hay quien se entere de nada. Mi caldera no tiene esas dos válvulas, solo tiene una, y tampoco tiene las dos llaves negras de los tubos junto a la pared. Por lo demás es idéntica y le pasa exactamente ese problema de no tener presión , 2.0 bar y F20 parpadeando.

Thanks so much! 1am here in Scotland & freezing! Its unstuck & working! 😁👍
Thank you so much. I had given up hope until seeing this video. Sorted thanks to you👍👌🏻
Huge thank you for this video! I was seconds away from calling an engineer out and paying a hefty fee but this video was so informative and easy to follow!
I was looking for information on how to resolve this problem in the user manual but your video turned out to be more effective
Thank you a lot !
My pressure is at 3.1 and its been stuck on that for the past year , is this too much pressure or an issue with the gauge
Thank you ever so much
A video cant be this clear and informative and covered all different boilers.
Cant Thank you enough for this video
You saved my day ❤
GENIUS IT WORKED !!!!! 👍👍👍👍🥳
Thanks for the easy to follow guide mate 👍

legend mate thanks for this saved me a cold night with the wife and kids!
Thank you for a clear explanation, you legend.
I tried and it worked 👍
Thank you 🙂👍✌️
Brilliant video, thanks a lot 👍
Great video
Great video thanks 👍
Thank you for the recommendation, ps how do you turn the pressure down..on eco fit pure
Amazing video. A coffee coming your way :) Panic stations but all good now after adding a bit more pressure

Thanks mate - saved me a lot of time!
Thanks a lot. It worked for eco tech pro🎉
A faulty boiler bleeder valve can trip an F 75 as air is trapped in the boiler operating system?
Life saver!
Thank you!!! it worked
Thank you.
I got the f75 but my electronic reader says 3.6 bars while the little dial shows that’s its so low that’s it’s gone below the grey bar. Do I still try opening the tap?
It worked like magic. Thank you
Hey Mark - i face an issue with My Vaillant Eco Tec Pure - F00…is there a workaround?
Brilliant thanks

Why do I have this every winter 😩

I'm getting a f75 on my valiant and the gauge is going high

Error f71
So useful!!! Thank you… clear instructions! Saved me from forking out money!!😩🫶👍🏻
