Why Is My Dishwasher Running For Hours? Here’s The Solution!

Dishwashers are an essential part of any modern kitchen, saving us precious time and effort. However, when your dishwasher starts running for hours on end, it can be frustrating and perplexing. Understanding the reasons behind this extended runtime is crucial to resolving the issue and restoring your dishwasher’s efficiency.

Common Causes of Excessive Dishwasher Running

1. Dirty Filters

Over time, food particles and grease can accumulate on the dishwasher’s filters, obstructing water flow and reducing cleaning effectiveness. This forces the dishwasher to run longer to compensate for the reduced water pressure.

2. Clogged Drain Hose

A clogged drain hose can prevent water from draining properly, causing the dishwasher to continue running in an attempt to flush out the water. Check for any kinks or blockages in the hose.

3. Faulty Water Inlet Valve

The water inlet valve controls the flow of water into the dishwasher. A malfunctioning valve can cause the dishwasher to run continuously without filling properly.

4. Overloaded Dishwasher

Cramming too many dishes into the dishwasher can prevent water from circulating effectively, resulting in poor cleaning and extended running times. Load the dishwasher according to the manufacturer’s instructions.

5. Incorrect Water Temperature

Dishwashers require hot water to clean dishes effectively. If the water temperature is too low, the dishwasher may run longer to compensate for the lack of heat. Ensure that your water heater is set to the recommended temperature.

6. Faulty Control Board

The control board is the brain of the dishwasher, managing all its functions. A malfunctioning control board can cause the dishwasher to run excessively or not at all.

7. Power Surges

Power surges can disrupt the dishwasher’s electrical system, causing it to malfunction and run continuously. Use a surge protector to safeguard your dishwasher from voltage fluctuations.

Troubleshooting Tips

1. Clean the Filters

Regularly clean the dishwasher’s filters to prevent clogging and ensure optimal water flow.

2. Unclog the Drain Hose

Disconnect the drain hose from the dishwasher and check for any blockages. Clear any obstructions and reconnect the hose securely.

3. Test the Water Inlet Valve

Turn off the water supply and disconnect the water inlet valve. Manually open the valve to check if water flows through it. If no water flows, replace the valve.

4. Load the Dishwasher Properly

Follow the manufacturer’s instructions for loading the dishwasher. Avoid overloading it and ensure there is sufficient space between dishes.

5. Adjust the Water Temperature

Check the temperature of the water supply to the dishwasher. Adjust the water heater to ensure the water temperature is at least 120°F (49°C).

6. Reset the Dishwasher

Unplug the dishwasher for 30 seconds and then plug it back in. This may reset the control board and resolve the issue.

7. Call for Professional Help

If the above troubleshooting steps do not resolve the issue, it is recommended to contact a qualified appliance repair technician.

Wrapping Up: Ensuring Dishwasher Efficiency

Understanding the reasons why your dishwasher is running for hours is essential for resolving the problem and maintaining its efficiency. By following the troubleshooting tips outlined above, you can restore your dishwasher to its optimal performance and avoid unnecessary frustration. Remember to clean the filters regularly, check for blockages, and ensure proper loading and water temperature to prevent future issues.
