pump blockage, switch power off to washer.drain machine manualy by lowering drain hose into a bowl.remove lower back panel.follow the drain hose into the washer,the pump is on the end of the hose.you will see a black rubber pipe between the drum and the pump.remove that pipe where it joins onto the pump.squeeze together the spring clip to release and pull pipe off.check for any blockage in the pipe and make sure pump turns freely .if all appears ok,then suspect pump issue or associated wiring.only remove the front filter inspection cover as a last resort,if it hasn't been of for a while it will more then likely break.
