What This Means

Heater engagement fault (out of place); Air hose out of place causing water leakage during spin cycle; Tub back broken at safety bolt fixing point; Water leakage at front from excessive foaming due to too much detergent; Connecting hose to detergent drawer connected incorrectly; Drain pump filter cover engaged incorrectly; Water leakage at drain hose; Duct condensing holding screws are worn; Nozzle-diaphragm engaged in opposite direction or rubber packaging omitted; Screws holding tub back and front fastened incorrectly; Leakage sensor is faulty

What actually causes this:

Water is leaking inside the washer, often from the drain filter not being screwed in tight, a loose hose, or too much detergent causing foam overflow.

First Thing to Check

Check the drain pump filter door at the bottom front of the washer — make sure the cap is screwed on tight and not cross-threaded.
