Washer fills and drains repeatedly without progressing through the cycle.

How to Fix / Troubleshooting

Safety first: Unplug the unit before hose inspection.

Check drain hose height: Ensure the drain hose is installed at the correct height and not sealed tightly into the standpipe, which can cause siphoning.
Inspect pressure hose: Verify the hose from tub to pressure switch is clear and properly connected at both ends.
Replace pressure switch: If the hose is good but behavior persists, the pressure switch may be faulty and should be replaced.

When to call a technician: If the issue remains after these checks, the main control board may require professional diagnosis.
