Hi, I am after some advice please.
My 10 year old Baxi Combi 105e has recently developed a mind of its own and will not switch the central heating off! It is controlled by a remote, wired Danfoss TP5 controller which will bring heating on at set times but the boiler will not switch off even with controller showing off. I have tried switching the boiler off at boiler on/off/reset switch and swiching to hot water only but the radiators continue to heat up. (In my opinion the radiators seem to be a lot hotter than normal.) The only way to switch off is to switch the boiler fused spur to off, which isn't ideal as my boiler is in the loft. The Fault on Central Heating Sensor Warning light is flashing, can it be as simple as a sensor change?
I don't know if it's linked but over the last few months my hot water supply has been intermittent although I did have a diaghragm replaced.
Also in the last year I did replace the PCB for a separate snag which has not re-appeared.
Any Ideas?
Many thanks.
