The thermal cutout on my Potterton boiler keeps tripping. I had an engineer out who said he adjusted the gas pressure (?) and it worked ok for a few days but the problem soon returned. The only clue I can give is I can't hear the water circulating when the timer switches on in the morning as I used to but the CH pump seems to be working. I can push the cutout in and everything works ok for an hour or two, but then it trips. Any clues please?

Check all the obvious stuff like pump working, bypass fitted if needed with all trv's system, 2 port valve not shut and system working constant, all controls components function properly, cold feed not blocked header tank full, etc, if all these ok change both over heat stat and boiler stat they are very cheap and have had them cause that fault twice this year with no call backs when new stats fitted.
Also check pump over run is wired correctly

It's a Profile 50e. Sealed system. It's been working ok for 12+ years so i'm sure it's something that's gone wrong with a componant.

...and the pump is pumping, sounds like you answered your own question earlier. Is the pump impellor clear, and are both isolation valves open!

I can feel the vibration on the pump case. Is there any other way of checking? Also, how can I test the motorized valve is working correctly?
