Recently, my Baxi 80E packed up & i wasn't getting any hot water, the CH worked fine with no probs. So i replaced the punctured diaphragm which solved the hot water problem. However, the central heating has now stopped working When I switch on the central heating the boiler comes on for about 10 seconds & cuts out again The red pilot comes on indicating pilot light failure!! I have now discovered that if i keep re-setting the boiler, the central heating, if it feels like it, might kick in, generally it doesnt Urgent help needed in these freezing times!! Does anyone know what the problem could be? Thanks for your time & patience.
