Hotpoint Dishwasher overflowing

If your Hotpoint dishwasher is overflowing, start with the most likely cause: a bad water inlet valve that is stuck open or dripping water into the tub when it should be shut off. This is a common reason for a dishwasher overfilling with water, especially if you notice water collecting in the bottom between cycles. Next, check the main control board, since a board that keeps sending power to the water inlet valve can also cause a dishwasher water level too high condition. A cracked lower wash arm assembly can also mimic a Hotpoint dishwasher overflowing by spraying water out the bottom of the door, and using too much detergent or the wrong detergent can create oversudsing that looks like an overflow. If those check out, inspect the control board and the float switch, because a stuck or failed float switch may not stop the fill cycle when it should. Enter your model number on RepairClinic.com to find the exact Hotpoint replacement part for your dishwasher, whether you need a water inlet valve, main control board, lower wash arm assembly, or float switch.

01 - Hotpoint 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 - Hotpoint 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 - Hotpoint 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.
