on my baxi 105e combi boiler. when i run hot water the boiler doesnt always switch on. it seems that if i open the hot water tap and then close it off, it will then switch on.Sometimes i have to turn the tap on/off several times.
The central heating seems to be ok.
can anyone make any suggestions please?
