Hi, I'm looking for some advice.
I have a Powermax 140 combi boiler, and for the last few years it's been making a whirring noise when it kicks in. The whirring kicks in for about 5 seconds and then the burner lights up. It then stops when the burner stops.
It sounds like a loud fan which is gradually getting louder.
Any ideas? If it is something like a fan how much is it to replace this on one of these boilers?
Thanks in advance for your help.
