Place four thick towels around the washer to catch any leaking water.
Touch "Power" to cancel the currently running cycle. Turn the washer's knob to "Rinse, Drain & Spin" to clear out the washer's water.
Open the washer's door and wipe down the seal with a damp cloth. Detergent buildup causes the washer to leak when the door's seal cannot properly suction to the washer's door opening.
Pull out the washer from the back of the wall. Turn it around to access the water supply line.
Place the wrench around the hot water inlet hose's coupling. Slowly turn the wrench clockwise to tighten the hose's connection.
Repeat the coupling tightening process for the cold water inlet hose. Avoid over tightening the connection as this can cause the coupling to crack. Stop turning the wrench once the coupling stops moving to secure the hose without damaging it.
Turn the cycle knob to the desired wash cycle setting and push "Power" to restart the cleaning cycle.
