Hi,
I have a problem with my boiler, a Worcester Greenstar 42CDI installed in 2008.
Ocassionally, it doesn't fire up when the thermostat sends in the signal. The thermostat displays the flame and on the receiver unit next to the boiler, I can see the Heating LED being ON - this goes ON at the same time with the thermostat, so I assume the signal is received properly.
However, the boiler doesn't fire - the flame LED on the boiler doesn't light up and the boiler is not working.
If I manually lower the temperature until the flame is not displayed and then increase it again, effectively re-sending the signal, most of the time it works.
But if I don't do that, it stays in this state and the temperature drops.
Very unpleasant as sometimes the house is really cold in the middle of the night and in the morning and I have to go downstairs to set it off again.
Most of the time, the boiler works though, so the problem is very intermittent.
The hot water is not affected by this, only heating.
Are there any known technical problems/gotchas with this model? Any known solutions? Has anyone else experienced this?
Many thanks,
Mike
