Hi,

I've got a Halstead Quattro Gold combi boiler, the other day the hot water stopped working but the central heating is still fine. The water does warm ever so slightly but would describe it as luke warm at very best.

Now looking through some of the threads on here, people have suggested the diaphragm on the diverter valve. A plumber friend has had a quick look and shown me that the pin is actually rising to meet the diverter switch (so unlikely to be the diaphragm). He's a bit stumped as he hasn't had much experience with Halsteads.

Does anyone have any other suggestions as to what may be causing the problem?

Thank you!

Some extra info:

When I turn the hot water tap on the boiler does light and stay lit until I turn the tap off again. Someone has suggested this means the microswitch is OK

Thanks for the input a. The micro switch is activated. How do I check if it is defective?

Thanks,

(the pin is actually rising to meet the diverter switch)
check that the pin activates the the micro switch and check micro switch is not defective
