Clock stopped on boiler.

[managed]

Hi, I have a Worcester Bosch Greenstar 30Si combi boiler, the analog clock has stopped and the On-Timer-Off switch only works on Timer setting,.
So I have set all the little timer switches to ON and the boiler does work then.
Any help or source for a new clock would be great.
TIA

Thanks for replying Shaun. Yes the timer is the Mt10 type.

Will need a gas safe engineer then sorry to say as it means breaking / going past the combustion chamber seal etc
