    Hello,

    We had a small power cut today (about a minute).

    After which the digital timer on the boiler has no display. Ive tried pressing the reset button but it hasnt done anything.

    The boiler is a Remeha Avanta Plus.

    The clock is part number S62432

    Ive phoned Remeha as the boiler is only 14 months old and came with a 5 year warranty, but they say the clock was an optional extra and is not covered.

    Is there anyway to revive the clock or do I have to shell out for a new one?

    Thanks.

    Stew

    I assume that you have checked the mains supply, and any fuses.

    From an electronics point of view, digital timers normally have a small re-chargeable backup battery which can fail if left to totally discharge.

    Also it is possible that the battery terminal voltage has dropped too low for the clock to reset.

    If you can isolate the supply and look inside, you may find a small Nickel Cadmium battery which you may be able to replace.

    Sometimes you can get things to reset by temporarily disconnecting the battery, powering the clock up, and re-connecting the battery.

    If it is totally worn out, then it will not recharge, so replacement of the battery is the only option.

    I just realised I never came back to this.

    I took the battery out and re-inserted it.

    The clock powered up and has been fine ever since.

    Thanks, :D
