Worcester 350 combi overheating

al.b · 12 Mar 2006

My worcester 350 combi will run up the central heating but then overheats and pops the red button on top of it, needing resetting before it will start again. Any help out there?

pump has gone

Thanks for that. But my rads are getting very hot when the boiler is running.

Could it still be the pump? The system is in a flat supplying 7 radiators.

i think the 350 has 2 pumps. the one for central heating sounds like its gone lazy.

More likely the central heating thermistor.
Turn the temp control knob down to a very low setting if it still does it my money is on the thermistor.
