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.
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.
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?
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.
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.
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.

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 for a clear explanation, you legend.
Thanks for the easy to follow guide mate 👍

Brilliant video, thanks a lot 👍
I tried and it worked 👍
Thank you 🙂👍✌️
Great video
Great video thanks 👍
Thanks mate - saved me a lot of time!
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 a lot. It worked for eco tech pro🎉
Thank you!!! it worked
Life saver!

Hey Mark - i face an issue with My Vaillant Eco Tec Pure - F00…is there a workaround?
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?
Brilliant thanks
Thank you
It worked like magic. Thank you
