Vailant F62 fualt code

[Yukster]

I get an F62 fault code on my valiant EcoTec boiler. There are no other gmfult codes apearing.

Everything that i read online including on this forum says that its either a gas sensor or gas pleasure problem.

I contacted two heating engineers, one of them has serviced my boiler for some years and he seems sterighforward. Neither of them think that this is a gas valve or supply issue. Both seem to think that the fault code is caused by a faulty pcb which is expensive to replace.

Can anyone here offer a view on what the fault is or likely to be? TIA

I didn't even know gas pleasure was a thing. Why don't you trust your regular engineer or the other one? All I can give really as advising on a gas related problem is prohibited as per the rules when you signed up
