I have an alpha CB28 boiler. The hot water only works when the CH is on too, and then not always.
From what I have read on here my understanding is that I probably have a problem with the DHW flow micro switch, or the diaphragm inside the diverter valve assembly.
Can someone tell me about the DHW flow microswitch. I have unclipped it, and tried pressing it, with and without a hot water tap on. The switch looks fine, and clicks, when I press it, but it does not ignite the boiler or seem to do anything. (whether the hot water tap is on or not). Does this mean the switch is broken, or could it still be the diaphragm?
Thanks in advance for any help.
