I have a problem with my Potterton Promax Combi HE Plus boiler?

Thank you for taking the time to give me some advice.
My gas fitter is really nice and helpful, but he said himself, as the fault is intermittent, he could not be sure it was the fan playing up but as the wiring seemed OK when he checked it, the error code given meant it was probably the fan. I will mention the pressure switch to him. It seems strange that it works fine just for the central heating, but the problem just seems to happen when running the hot water.

i would be cautious as these boilers have a common air pressure switch fault there around £30 and take 5 mins to fit. i fixed alot of these and i would look at replacing this little item before looking at the fan or pcb. a fan can be tested easily and normally when they go its quiet obvious

sounds like you dont have faith in your gas engineer
you might be better off going with a one fixed fee repair with the boiler manufacturer
if they cant fix the boiler then no one can
