Hi: Biasi Riva Compact M90e 24s 2004 Model
CH pressure switch And DHW switch ok
All lights ok green and green flashing getting and switches to hot water ok. Problem is hot water goes on and off boiler screams slightly befor reaching peak scream boiler shuts down and starts 4 seconds later water coming from divertor valve and small release port on top of pump.
Indicates divertor valve. Took out divertor, valve pin pushes ok although plenty light oxide.
Any ideas ie divertor valve repair kit new divertor valve. cheers steve
