Did you get 230volts at the pump?

Have u checked the pump dia or m/s?Very rarely does that light mean that the pump is faulty. It's just giving a general area that the fault lies.

If the micro switch doesn't make via the pump dia/pin then you'll get the pump fault led

after pushing that switch up if it fires you have a diapragm gone or a blockage in the small orifice under it
