Hi everyone.
Can anyone out there advise me as to whether the micro switch at the end of the diverter valve on my hrm wallstar combi boiler just pulls away from the valve. Or am I going to find a circlip or something similar holding it on.
The reason I ask is because I recently had the diverter valve replaced, and although it has 90% cured my dhw problem, the other 10% of the time I'm still getting cold running water when asking for hot.
I'm wondering if over the years the paddle on the micro switch has worn/bent
Thanks in anticipation
Peter
