Standing water in the tub at end of cycle
Filter, then drain hose, then pump — in that order. 70% of 'won't drain' is a filter that's never been cleaned.
Diagnostic flow
- 1
Remove and rinse the filter assembly
Twist the upper cylinder counter-clockwise, lift out, then lift the lower mesh. Rinse under hot water — every 30 days as routine.
- 2
Bail the standing water
Use a sponge / turkey baster until the tub bottom is dry.
- 3
Inspect the drain hose loop
Under the sink, the hose must loop ABOVE the disposal inlet (high-loop) to prevent backflow.
- 4
Test the disposal connection
If you recently installed a disposal, the drain knock-out plug may still be inside — pull it.
- 5
Test the drain pump
Remove pump cover under the filter housing. Spin the impeller by hand — sluggish or stuck = replace pump WD26X23258.
