Most Frequent Causes for Dishwasher overflowing

Cause 1Water Inlet Valve

The water inlet valve is an electrically-controlled valve that opens to allow water to enter the dishwasher. Depending on the model, the valve stays open either for a set length of time or until the dishwasher has enough water. However, if the water inlet valve doesn’t shut off after the dishwasher has enough water, the dishwasher will overflow. If water drips into the dishwasher when the door is open, or if water collects at the bottom of the dishwasher while it is not use, you may need to replace the water inlet valve.
