What This Means

Heater engagement fault (out of place); Air hose is out of place causing water leakage during spin cycle; Tub back at the safety bolts fixing part is broken; Water leakage at the front due to too much detergent causing foaming; Connecting hose to the detergent drawer is connected incorrectly; Drain pump filter cover is engaged incorrectly; Water leakage at the drain hose; Duct condensing holding screws are worn; Nozzle-diaphragm is engaged in the opposite direction or rubber packaging is omitted; Screws holding the tub back and front are fastened incorrectly; Water supplied continually because the water level detection does not work; Faulty valve causing continuous water supply

What actually causes this:

A hose connection came loose or the door seal (diaphragm) is not seated properly — using too much detergent can also cause suds to leak from the front

First Thing to Check

Check if you're using too much detergent — use only HE (High Efficiency) detergent and measure carefully. Check the drain pump filter at the bottom front for a loose cap.
