rayburn 480k mkii ciculation pump

[boconnoc]

The circulation pump will not shut off and keeps running. the only way to shut it off is to turn off the electric supply. i am wondering if the pump overrun stat is at fault. if so can it be adjusted or do i need to replace it. Thanks

You can't adjust the pump overrun,if it's faulty then it will have to be replaced. It's behind the thermostat panel.

These machines have a mind of their own! I have one (rather kaput now) and more recently the pump's been going, then it hasn't, the water's boiled then been normal, it short cycles one day then the next it's perfectly normal.

How old is your's (if that's not too personal a question)?
