I have a Baxi Combi 105e boiler which was fine until a few weeks ago.
If I turn on the central heating or hot water, it warms to about 50 degrees but no more. When it is then switched off, the thermostat light flashes.
The two dials to control the temperature are up full and there is no room thermostat.
I have replaced the thermostat, both the temperature sensors and the heat exchanger but still the problem persists.
Does anyone know what else I can try?
Many thanks in advance.
