Sorry, been away.
The reset did not work - can you tell me what happens if you turn off at the fused spur for a couple of minutes.
Can you tell me exactly what the boiler does, clicks, fan, etc.
Customer: replied 4 years ago.

it clicks no sound from pump?

Expert:  Andrew Smith replied 4 years ago.
If the room stat is calling, the first thing that should happen is the pump should run and the boiler should fire.
If on hot water only then the boiler should not fire until the hot water flow switch starts the boiler
Customer: replied 4 years ago.

so it could be the pump?

Expert:  Andrew Smith replied 4 years ago.
Can you check if the pump is running? You can check by taking the screw out of the centre and see if the centre is spinning inside?
Customer: replied 4 years ago.

its not spinning, it turns free with boiler off.

Customer: replied 4 years ago.
