Baxi Combi 105e problem

Hello

My boiler seems to have developed a fault. The hot water is fine but the central heating doesn't work. No fault lights are on.

    How are you trying to turn the heating on?

    Have you tried putting the timer on constant, also is the CH thermostat (on the boiler) set high, does the room thermostat click when you turn it up, is the mode selector set to CH + HW?

    Mode selector is on CH + HW, timer is on constant and CH thermostat is set to max on boiler. The room thermostat doesn't click anymore.

    The only way to be sure is to check the connector block on the PCB.

    You will need a multimeter or a heating engineer for this.
  • I connected up terminals 1 and 2 together and the CH works!!!:beer:


    Next question is is it the themostat on the wall or the timer?:confused:
