Does not drain fully hence red light flashing.Manually drained water from drum via front hose.Checked pump,running fine.Removed drain pipe and cleaned,checked sink trap for blockage.Any suggestions?
is the pump noisey when you run it, if you get sideways movement in the impellar towards the outer edge you have wear in the pump which may not work under load and would need replacement, if ok go back and check sump hose and waste outlet hose for further blockage
