The Kenmore dishwasher F4 error code indicates that the dishwasher has failed to drain within the expected time. After a wash or rinse cycle, the dishwasher activates the drain pump to remove water. If water remains in the tub after the pump runs for the maximum allowed time, the F4 error is triggered.
Common Causes of the F4 Error
- Clogged drain filter or sump strainer
- Blocked or kinked drain hose
- Clogged garbage disposal or sink drain (if connected)
- Faulty drain pump motor
- Check valve stuck in closed position
Troubleshooting Steps
- Remove and clean the filter/strainer assembly at the bottom of the dishwasher tub.
- Check the drain hose under the sink for kinks or blockages.
- If connected to a garbage disposal, ensure the disposal is clear and the knockout plug has been removed.
- Reset the dishwasher and run a drain/cancel cycle.
- If water remains, the drain pump requires professional service.
