All,
I have the above boiler, it has now started to fire up (and then stop) intermittently when all controls are off. I have put on a new programmer, this seemed to improve it for one day only (red herring?).
I can stop it running by switching the "economy" switch to "off" or "low" but then the boiler won't fire up when it is switched on.
Because of this it can't be left in the normal "off" state, it has to be switched off at the mains.
Any ideas?
Thanks
Steve
