hi got a gloworm 38CXI CH appears OK. hot water startts OK then cuts out to luke warm . filters are OK.
conections ok on boards any easy checks with a multi meter?
have run it with and without CH running doesnt make any difference to the time period before the boiler appears to back off and water gos to luke warm but not not cold
