Does it work on heating?
got the c/h working pressure gauge headed off toward 4 so let the pressure relief off which now wont stop leaking i,ve put some cleaner in the system . it all started with a leak on the 3 way valve all gacked up changed that and the motor valve on top of it as it corroded due to the leak changed the pcb to try and cure the h/w
Sounds like you have a few issues at the moment. Maybe you should get someone in before fitting anymore parts. Was a new PCB just a guess?
You could have a blocked plate heat exchanger and a flat expansion vessel. Also sounds like you need a new PRV now!

You don't need a new boiler, just someone that know what they're doing.
