Sometimes water stops draining due to a kink in the drain hose. Pull the washer out from the wall, and check for kinks before beginning. If there are no kinks, clearing the drain pump and filter may fix the issue. This is a much more involved process that involves removing the filter panel and carefully dismantling the pieces for inspection and cleaning./
Unplug the washing machine from the electrical outlet. Pull it out from the wall. Tilt the front of the washer up, and brace it by placing blocks under each foot.
Locate the three screws at the bottom of the panel. Remove these screws using a Phillips screwdriver. Place the screws in a secure location. Lift and remove the panel from the machine.
The drain pump is in the middle of the machine and is sealed with a knob attachment. Place the bucket underneath the drain pump to catch overflowing water, and remove the knob attachment.
Turn the knob over, and inspect the filter on the back. Remove any debris with a bristle brush or soft cloth. Rinse the filter with water.
Replace the knob and back panel. Remove the braces from the front of the washer, lowering it to the floor. Plug the washer back in to the outlet.
