Potterton Suprima 60 - Hot Water won't go off

[KatieNic]

I have a Potterton Suprima 60, whose hot water will not turn off. The heating works (ie goes on and off). The boiler has a constant green flashing light and fires up every 5 to 10 mins. The only way to turn off is by the mains. I am concerned that it may blow the whole system if I leave it on.

Any advise would be great as only spent a fair bit on new pcb 2 1/2 years ago.

Thanks

Kate
