The water just keeps running into the washer tub even after it's filled, spilling over onto the floor. There is no error code.

    There are three factors that make cause the water overflowing the tb of you washer.

    1. Water Inlet Valve

    If the top load washer is overflowing even when the power is off, then the water inlet valved is not working. You will need to replace it and make sure its replaced by a  experienced technician.

    2. Pressure Switch

    The pressure switch is attached to a small tube which is attached to the outer wash tub. As the water level rises the air pressure in the tube increases, once the set water level is reached the pressure switch turns off power to the water inlet valve. Check to be sure the air tube to the pressure switch is clear before replacing the switch.

    3. Low Water Pressure from House Supply

    If the washer is overflowing the water pressure to the water inlet valve might be too low. The water inlet valve requires a minimum of 20 psi to shut off properly. If the pressure is lower, the valve may not close fully when the power is shut off. This results in the valve leaking water into the washer and causing it to overflow.
