Hello ,
I have the above boiler and have no hot water at the sink but the central heating works.
From what I have read is it the diaphragm that operates the micro switch ? I suppose it could also be the micro switch but most of what I have read appears to suggest the diaphragm.
Is there a way to test using a multimeter on the pcb to prove its the diaphragm?
Any advice greatly appreciated.
