Valiant ecotec pro 28 boiler

[Simon McAleenan]

Hi anyone,
Well got a f25 fault on my boiler and cant seem to get rid of it. My plumber has changed the pump/ water pressure sensor/ prv/ igniter cable and ntc sensors on the flow and exchanger. It worked for about a hr then went off again with the same fault code again. Please any ideas?? Desperate been over a week now no hot water or heating

you are not alone , well known problem with your bolier, there is a F75 fault kit available, terrible boiler, see if you can get a vaillant fixed price repair, you will get a 12 month warranty with it, or fit a decent boiler

To be honest we've had the boiler 12 years and never had any problems. Other than 2 years ago we needed a new expansion vessel. The 2Amp fuse had blown and the 3amp in the wall. Can't understand how it ran for a good hr before going off then back to f25 fault.

sorry I misread your origional question I thought you had a F75 code not a F25 code

@ScottishGasMan is the man for this one, I have tagged him for you so he will see your post, could be the fuse harness but he will be able to advise better than me
