What to check first
Stop normal operation while this warning is active. Follow only the documented safe checks or protective-drain instructions for the exact model.
Basic checks
- Pause the cycle if safe and keep hands clear of the drum.
- Check whether laundry or other items are caught at the door opening.
- Close the door firmly and verify the latch area is not visibly damaged.
- Look for clothing, soil, or items at the latch area; if the door still will not close, do not force it.
- Close the door or lid once and listen for a normal latch response; if it does not change, stop retries.
