    Boiler
    Hello

    I've recently moved to a new flat and have a Combi Biasi boiler. The hot water becomes too hot then goes cold, I've had it checked thinking the thermostat had gone but the boiler chap said it was fine. Now the hot water turns itself off when running the water and I have to continually press the re-set thermostat button. Would anyone be able to help me decipher what the problem is so I don't have to pay for another call out fee on top of what I'll have to pay to get this fixed.

    Cheers

    Next time it does this check the boiler for a diagnostic light, it sounds like the boiler is locking-out and you are resetting it at the termostat.

    The control is allowing it to overheat causing the limit to trip. Replace the operating control.
