I have an Ariston Euro Combi Boiler SX20 MFFICE
The hot water only works when the heating is on.
I have changed the diaphragm but this has made no difference.
When I switch the micro switches manually the boiler fires up but when the hot water tap is turned on nothing happens. The pin from the diverter valve raises up as it should.
Any ideas please.
