My boiler is 3 years old. From long time ago it developed an annoying problem that when you turn on hot water while central heating is on, you get a big bang from the boiler, you can see the pressure gauge oscillating a lot when this happens. The boiler works perfectly for 3 years now but this banging worries me a lot. It seems when diverter valve switching from CH to DHW, the pump is still working, but when it switches from DHW to CH the pump stops for little while and therefore no noise comes out. I would assume it's a pcb problem, like a software bug in the circuits where the pump is not told to stop when diverter switches. Or probably it's only a faulty diverter? But the boiler has been working for 3 years no problem but only the annoying banging.
Searched in the forum, seems some other guys got this problem as well but none of them left message what's the problem in the end. Can someone spare ideas on how to fix this? Will new PCB help? I noticed Ideal released a new version of PCB to replace the original one. Thanks in advance.
