Hi everyone and a happy new year to you all,
We have developed a problem with our boiler, It’s Worcester 240 RSF approx 13 yrs old fitted by myself.
A few days ago whilst having a shower the water went to cold and the boiler I think tripped the reset button. Although we have a modern rcd the boiler was still powered up.
On removing the pressure chamber cover, the fitting on the left hand side that has the self vent was leaking at the large nut, dropped some pressure off the CH system, (I don’t know if this is part of the CH sys) and then turned off all ISO’s under the boiler.
Fitted a new fibre washer, pressured everything back up, and mopped up the water from the bottom of the tray in the combustion area.
On first testing all system seemed to be ok.
As the weather has been quite cold I was happy to let the boiler run and it would respond to the controls as it should, then during the next few hours and into the night I noticed the CH was still running the CH would not turn off.
The CH would run and not respond to any command on the room stat or front panel, even with the CH off on the front panel it would still run , if you turned the flame height control to it’s lowest setting it would go off for a few minutes then the boiler would relight.
During this time something electrical either shorted or over heated as there was a smell of insulation/Bakelite burning. The pump does smell a bit but it’s hard to tell.
The demand light does not come on for DH or CH, DH still works but is noisy but has been for some time.
When the fitting was leaking a small amount may have dripped through to the control area but was generally very dry.
My theory
1 pump failure
2 ghosts or other type of super natural intervention.
