hi my combi 80 heating is staying on when the timer is off, the only way to turn the heating off is to switch off completely from the wall, can anyone help?
if your boiler is a baxi 80 echo, then the 3 way microswitch on the water valve is stuck in open position. do not use boiler until you change!!!!! boiler thinks hot water on all the time, will cause many problems including divertor valve, p.c.b. peterbow
