General Electric Dishwasher overflowing: Common Causes & How to Fix

Repair Instructions:

The water inlet valve is an electronically controlled valve that opens up to let water flow into the General Electric dishwasher. Depending on the General Electric dishwasher model, the valve stays open for a specific duration or until the General Electric dishwasher has enough water. If the water inlet valve doesn't close after the General Electric dishwasher has enough water, it can cause the General Electric dishwasher to overflow. If you notice water dripping into the General Electric dishwasher when the door is open or if water accumulates at the bottom of the General Electric dishwasher when it's not in use, it might be necessary to replace the water inlet valve.

The General Electric dishwasher pressure switch is an important part that tells the water inlet valve to close once enough water has entered the General Electric dishwasher for a wash cycle. If the pressure switch is not working properly, it may not send the signal to close the inlet valve, leading to an overflow. To check if the pressure switch is working correctly, you can use a multimeter to test for continuity. If the switch is shorted or fails the test, it should be replaced with a new one.

How to Replace General Electric Dishwasher Pressure Switch
