There is no blockage to the discharge pipework and no leak into the base. What should I check next?
Hi. The control panel works fine (I can hear contacts making when I push the reset but does not stop the pump) and programme changes when I select the programmes but pump still continues to run. Checked micro switch on flood device, all OK.
Have not had the metering tank and pressure chambers off yet. I am an air conditioning engineer so understand electromechanical principals. How does the controller know when to stop the pump or is it local control i.e via a level sensor etc wired thru the pump?
