The over heat switch on my worcester 350 combi boiler cuts in if I use the hot water (taps only the shower is fine). All I have to do is flick the switch back and all is fine again. I got a plumber out to look at the problem and he couldn't work out what was one with the boiler can anyone help me with this problem. I think it overheats as the boiler kettles and then the fan comes on as it cuts out. Is there anyway I can find out what is wrong with the boiler.
