Water Inlet Valve

If the ice maker 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 ice maker and causing it to overflow. If the water pressure is good, replace the water inlet valve.
