A GE washer may overfill or overflow because of a malfunctioning water level switch or a broken water inlet valve. Low water pressure from the house supply may also cause a washer to overflow.
Problems in both the water level switch and water inlet valve can be diagnosed by filling the machine half-way with water and unplugging the unit. If the water continues to run after the washer is unplugged, the water inlet valve is malfunctioning. If the water shuts off, the problem may be the water level switch.
When replacing a water inlet valve, the machine is unplugged and disconnected from the water supply. The control panel is unscrewed and removed, and then the water inlet valve is disconnected and lifted out. Next, the replacement water inlet valve is put into position, the hose is attached and clamped securely. The mounting plate is secured, and the wires are connected to the new valve's terminals. Finally, the cabinet, control panel and water supply line are put back into place, and the water supply is reattached and turned on.
The water level switch is replaced by unplugging the machine and removing the dial used to select the load size. The switch is exposed by removing the control panel, and is lifted out after disconnecting the wiring and hose. A new water level switch is then placed into position and securely connected to the wiring and hose. The control panel is reassembled, the dial is replaced, and the machine is plugged back in.
