My problem is;
The central heating was being put on the other day for the first time since the winter. I found that the motor in the drayton mid position valve was burnt out, I replaced this and fired the system up. Everything appeared to be working ok. However after 40min the pump stops running and the boiler will only fire up for a few minutes at a time, Cutting in and out on the boiler thermostat. This will continue and the radiators upstairs will heat up slightly and the ones downstair will cool down completly.
I checked the connections on the pump and there is no power there.
The water heating works fine.
The boiler is a glowwarm,
The mid position valve is a Drayton lo3030
It uses a drayton timer and room thermostat.
Any help would be great.
Cheers
Stu
