Before you call
Safe checks you can make
These are simple, non-hazardous checks only. If anything is unclear, stop and contact a technician.
Check the drain hose for a kink, pinch, or obvious blockage.
Verify the hose is installed at the correct height and is not pushed too far into the standpipe.
Remove any accessible items that are blocking the external drain path.
Run a drain/spin cycle once after correcting an installation issue.
Important safety warning. Stop user-level troubleshooting if the code returns after one safe reset/check cycle or if the washer shows leaking, overheating, electrical, or mechanical symptoms.
