• Washer may display a long-drain condition after basic hose and filter checks.

Check Before Replacing

• Disconnect power before servicing.
• Check the accessible drain hose, pump filter, and pump inlet for obstructions, following the washer’s service or owner documentation.
• Visually inspect the pump wiring connector and harness for looseness or damage.
