1) halsted finest gold - gas
2) diverter pin not moving
3) no recent work/changes
4) problem started 1st jan 2009
5) when hot tap/shower is turned on, DHW pin does not move
6) bled all rads, pressure when CH is on maxes at 1.5 bar-ish
hi experts, i have a halsted finest gold and the pin at the end of the diverter valve that usually presses the DHW microswitch is not moving as expected.
i realise this is typical of a diaphragm failure but i was wondering if there was anything else i should check before calling a plumber or attempting diy (i am an engineer but not a boiler one). i was thinking maybe the expansion tank pressure may be low - would this affect actuation of the diverter?
