Not draining

This is a washing-machine fault guide. The code above comes from the washer display; it is not the model number. Model-gated checks for 5C / 5E / nd / SC or water left in the drum.

Stop immediately for smoke, burning odor, sparking, violent movement, or water near electrical parts. Do not touch a wet plug.
