hi my ravenheat boiler model rfs84et has no hot water boiler will not fire up when on hot water only ok on heating but still no hot water when tap is turned on could this be a diverter valve or micro switch problem any help welcome thanks.

Its likely to be the D/V check the pin is extending fully on to the microswitch

If not energise the switch with a screw driver, boiler should then light
