Problem with timer clock on Vaillant TurboMAX 828

[peca27]

Afternoon all

I've got a Vaillant TurboMAX 828, had it 7yrs now + it's working well......only had to replace a divertor valve + air pressure switch in the time I've had it.

But now I'm finding the timer clock on it is slow, eg over 24hrs it seems to loose 3/4 hrs + therefore doesn't show the true time at all times. Does the clock become faulty over time? I thought it was mechanical, can't figure out how it's got faulty.

Is it simply a case of buying another timer clock?

Many thanks for the help all.

Cheers for that Gordongas..........

Was just checking online + it seems that the cheaper option is another mechanical clock, not a digital?

Unless you mean something else by an 'external digital'?
