User Suggested Solutions

Check and clean the drain filter and hose. Disconnect the washer from power, locate the drain filter (usually at the front bottom of the machine), and remove any debris. Also, check the drain hose for blockages.
Clean the door seal and detergent dispenser. Use a mixture of vinegar and water to wipe down the rubber seal and the dispenser, ensuring all mold and residue are removed.
Inspect and replace the water pump if necessary. If the machine is still not draining properly after cleaning, the water pump may need to be replaced. This involves removing the back panel and disconnecting the pump.
