A dishwasher is a convenient appliance that helps you save time and effort in the kitchen. However, when it starts running continuously, it can be a puzzling and frustrating issue. If you’re wondering “why is my dishwasher keeps running,” this comprehensive guide will help you identify the potential causes and provide solutions to resolve the problem efficiently.
Common Causes of a Continuously Running Dishwasher
1. Faulty Pressure Switch
The pressure switch monitors the water level in the dishwasher. If it malfunctions, it may send incorrect signals to the control board, causing the dishwasher to run indefinitely without stopping.
2. Stuck Float Switch
The float switch is a safety feature that prevents the dishwasher from overflowing. If the float switch gets stuck, it may falsely indicate a high water level, leading to continuous running.
3. Clogged Drain Pump
The drain pump removes water from the dishwasher. A clogged drain pump can obstruct the water flow, causing the dishwasher to keep running in an attempt to drain the water.
4. Control Board Malfunction
The control board is the brain of the dishwasher. If it malfunctions, it may send erroneous signals to other components, resulting in continuous running.
5. Leaking Water Valve
A leaking water valve can continuously fill the dishwasher with water, causing it to run without stopping.
6. Damaged Door Latch
The door latch ensures that the dishwasher door is securely closed during the wash cycle. If the latch is damaged or misaligned, the dishwasher may think the door is open and continue running to prevent leaks.
7. Power Surge
A power surge can damage the dishwasher’s electronic components, leading to abnormal behavior such as continuous running.

1. Check the Pressure Switch
- Disconnect the dishwasher from the power source.
