I keep gettting an error F21, slow drain time. I have followed the owners manual. to unplug unit, reset the buttons, check drain hose for clogs.
I removed the front cover, opened the tub drain trap. It was clean. I hear the water pump running, and a trickle of water is still draining. Is my water pump going out or is there a possible clog somewhere else?
Check and test all the wires between the pump and the control unit. If they check out, try replacing the pump.
