Dacor Dishwasher overflowing

If your Dacor dishwasher is overflowing, start with the most likely cause: a failing water inlet valve that is not shutting off when the tub reaches the proper level. A Dacor dishwasher overfills with water can also be caused by the main control board or control board continuing to send power to the valve, though that is less common. In some cases, what looks like dishwasher overflowing is actually water spraying out because the lower wash arm assembly is cracked, split, or damaged near the bottom of the door. Too much detergent or the wrong type of soap can also create oversudsing and leaking, and a stuck or failed float switch can let the water level get too high. If your dishwasher water level is too high, check for dripping water when the door is open, water collecting in the tub when the machine is off, damage to the wash arm, and signs the float switch is not moving freely. Enter your model number on RepairClinic.com to find the exact Dacor water inlet valve, main control board, control board, lower wash arm assembly, or float switch that fits your dishwasher.

01 - Dacor Dishwasher Water 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.

02 - Dacor Dishwasher Main Control Board

A dishwasher's main control board provides power to nearly every electrical component in the dishwasher. If the control board continues to send power to the water inlet valve during the drain cycle, the dishwasher could overflow. While this is not that common of a problem, you can inspect the board for signs of burning or a shorted-out component. You can also use a multimeter to test the water inlet valve for incoming power during the dishwasher's cycle.

03 - Dacor Dishwasher Lower Wash Arm Assembly

If the lower wash arm has a crack or split on the side it can cause water to splash out the bottom of the door, giving the impression that the dishwasher is overflowing. Inspect the wash arm assembly for any damage and replace if necessary.

04 - Wrong type or incorrect amount of detergent

Make sure to use the proper dishwasher detergent. Use the proper amount of detergent for your water hardness; too much soap in soft water can cause oversudsing and leaking.

05 - Dacor Dishwasher Control Board

A dishwasher's control board provides power to nearly every electrical component in the dishwasher. If the control board continues to send power to the water inlet valve the dishwasher could overflow. While this is not that common of a problem, you can inspect the board for signs of burning or a shorted-out component. You can also use a multimeter to test the water inlet valve for incoming power during the dishwasher's cycle.

06 - Dacor Dishwasher Float Switch

The float switch actuates in order to prevent the dishwasher from overflowing. If the float switch is defective or stuck, it might not stop the dishwasher from overflowing. If the float switch is defective, replace it.
