Hi I have a sime super 90 combi boiler that has heating but no hot water, could someone help???
I have changed the dhw thermistor only for the problem to still be apparent, if anyone could point me in the right direction it would be very much appreciated.
Check when hot tap opens does pin comes out on divertor valve and activevat micro switch. if not than diaframe in the divertor valve is worn out. If it does than fan should be operating than follow the manual fault findng and that will guide to the fault.
