User Suggested Solutions

Check and clean the drain filter. Locate the filter access panel, usually at the front bottom of the machine. Open the panel, remove the filter, and clean it under running water. Ensure no debris is blocking the filter housing.
Inspect the drain hose for kinks or blockages. Follow the hose from the back of the machine to the drain outlet. Ensure it is not bent or pinched and that water can flow freely through it.
Test the pump operation. Access the pump by removing the back panel of the washing machine. Check for any obstructions in the pump and test the motor with a multimeter to ensure it is receiving power.
