I have a problem with a Ravenheat CSI 85 (26 months old) which intermittently runs the pump even when i have not requested DHW / CH.
It can come on anytime during the day or night stays on from between two and twenty minutes then switches off. The boiler does not try to light and other than this the boiler is working fine.
If I turn the boiler off at the mains then back on this can sometimes stop the pump running and also if I run the hot water for a few minutes to heat the water up then it can stop it, I am not sure if this is relevant but it's not another thermistor problem is it?
Any ideas? - when it comes on at night i wake up and it's driving me mad!
