I have a Gloworm Flexicon HX30 boiler.
Even though the set temperature is 80 Degrees the boiler fires and continues to run, but will only run at a constant 57 degrees, occasionally it will run up to 80 then it falls back to 57 after a few minutes.
The boiler does not switch off and does not lock out and does not show a fault code, but just runs at the low temperature.
The engineer has replaced the main PCB but that made no difference.
He came back and replaced the thermistors and that has made no difference.
The engineer didn't seem to have any other ideas,and he spoke to his senior engineer and he had no idea either!
Has anyone else had this fault or has anyone got any ideas why it does this?
