Baxi combi 105e instant central heating not turning off

squashman · 6 May 2009

Hello,

Wondering if anyone can point me in the right direction. I have the boiler Baxi 105e Instant (combi) and sometime the central heating does not turn off. I get the flashing green light for the hot water? It seems that the thermostat does not kick in sometimes. Any suggestions?

Thanks

check the controls ie the timer and thermostat rather than the boiler
if the controls is calling for heat ,the boiler is only douing it's job

Ive checked the thermostat but what i have found out is that there is a leak under the seal of the diaphragm for the central heat valve (not for the hot water). I was wondering, if the diaphragm has be reptured could this be the cause of the problem?

if the hw demand light is staying on then you wont get heating

most likely cause is the dv
