Hi there,
On the weekend I noticed that there was water coming out of the expansion overflow pipe in the loft. The boiler was dumping hot water out of the expansion pipe into the tank. Turned the temperature control down on the boiler and it didn't happen again all weekend.
Then this morning the CH & HW came on as normal, but after an hour or so the red light came on to indicate a boiler lock out - had to reset to start boiler again. Boiler starts up, so then I slowly turn the temperature knob down to see if it would turn off. Managed to get it all the way round to the off position without it turning the boiler off.
System is 'C' plan (Gravity HW, pumped CH). Radiators are all getting hot (hotter than normal actually) and all bled. Pump bled too.
So, my assumption is that the temperature sensor is playing up?
Any help much appreciated
