I have Compact 75E combi boiler and the pump is continual on! The heating and the hot water works fine but the pump stay on continually even when not require.
I have two plumbers over and they have not been able as of the to find the fault. Do you have any ideas what could cause the pump to continually run?
thanks
Paul
