Potterton EP2002 fault



Hi there,

I have a Potterton EP2002 programmer that is causing the boiler to fire up - both DHW & CH - in all modes (except when programming the clock?) Even if i take the programmer off the backplate completely the boiler is still getting power and still firing up.

Any ideas?

Ok, but why if you don't mind my asking? What will i be looking for?

With all due respect guys, thank you for your help. I do know what a motorised valve is. I really can't see why it would be that? I believe the programmer is faulty, i was just seeing if anyone had some prior definite knowledge that could help me diagnose. If you're reading this thinking what an ungrateful cu**, you've got me wrong. Thanks for your help.
