1. Check if the drain hose is clogged or kinked. If it is, straighten it out.

2. Check if the pump filter is clogged. The pump filter is located at the bottom of the washer and can be accessed by removing the front panel. Clean the filter if necessary.

3. Make sure the drain pump is working properly. If it's not, it may need to be replaced.

4. Check if the drain pump belt is loose or broken. If it is, it will need to be replaced.

5. Ensure that the drain pump is receiving power. If it's not, check the wiring and the control board.

6. Check if the water level pressure switch is working properly. If it's not, it may need to be replaced.

7. Finally, if none of the above steps solve the issue, it may be a problem with the control board and will require professional repair.
