How to Fix Common Issues
Not draining
Check the filter and drain hose for clogs first. The pump may need replacement if it hums but does not drain. Inspect the impeller for debris.
E24 error
E24 indicates a drain or water issue. Clean the drain pump filter. Check the drain hose for kinks. Ensure the garbage disposal knockout is removed if applicable.
Spray arm clogged
Remove the lower rack and unscrew the spray arm. Clean the holes with a toothpick or pipe cleaner. Check the filter and clean it.
Door seal leak
Wipe the door gasket regularly. Replace if cracked or leaking. Ensure the door closes fully and the seal sits flat.

Check Drain Hose
Pull the dishwasher out. Inspect the drain hose for kinks or clogs. Ensure it is not looped too high. If connected to a disposal, verify the knockout is removed.
Test Drain Pump
Run a drain cycle. Listen for the pump—it should hum. If it hums but does not drain, the impeller may be jammed. Replace the pump if dead.
Inspect Door Seal
Wipe the door gasket. Replace if cracked or leaking. Ensure the door closes fully and the seal sits flat against the tub.
Run a Test Cycle
Restore power and water. Run a short cycle. Verify draining, spraying, and no leaks.
