Britony Combe SE 100 (Chaffoteaux)

[MrsGee321]

My radiators are overheating. The boiler is a Britony Combe SE 100.
I've just checked it and the "overheating safety" light is on.
Can you suggest anything please ?

Thanks

The thermostat is faulty.

Hi changed thermostat but still having problems.

Timer also not working. The timer turns around but when the boiler was on
the timer doesn't switch off so we use the main off and on switch to switch the boiler off.

This morning I switched boiler on and there was no flame.

The overheat thermostat has been changed as well as two thermisters.

The boiler switches on no problem but the radiatiors still get too hot.

Most of the rdaiators are heating up from the top though and the bottom is cooler.

Any ideas for next step?

Sounds like a lack of flow!

Clean the filter in the CH return!
