Status Light Indicators
Whirlpool dishwashers typically feature status lights that indicate various operating conditions. The flashing light can be a signal of an error, a warning, or a normal operation. Understanding the different light patterns is crucial for identifying the root cause.
Common Causes of Flashing Light
1. Door Latch Failure: A faulty door latch can prevent the dishwasher from starting or completing a cycle. Check if the door is securely closed and the latch is engaging properly.
2. Overfill Condition: Excess water can trigger the flashing light. Inspect the water inlet valve and hoses for leaks or blockages. Ensure that the drain hose is properly connected and not kinked.
3. Drain Pump Problem: A clogged or malfunctioning drain pump can hinder the dishwasher’s ability to drain water. Check for obstructions in the pump, filter, or drain hose.
4. Heating Element Failure: If the heating element is not functioning correctly, the dishwasher may not be able to reach the desired water temperature. This can lead to a flashing light and incomplete cleaning.
5. Control Board Malfunction: The control board is the brain of the dishwasher. A faulty board can disrupt various functions, including the status light.
6. Sensor Issues: Sensors monitor water levels, temperature, and other parameters. A malfunctioning sensor can send incorrect signals to the control board, causing the flashing light.
7. Power Surge or Outage: A power surge or outage can reset the dishwasher’s control board. This may result in the flashing light and require a reset.
Troubleshooting Steps
1. Reset the Dishwasher: Unplug the dishwasher for a few minutes and then plug it back in. This may reset the control board and resolve the issue.
2. Check the Door Latch: Ensure that the door is firmly closed and the latch is securely engaged. If the latch appears damaged, it may need to be replaced.
3. Inspect for Leaks: Examine the water inlet valve, hoses, and drain hose for any signs of leaks or blockages. Tighten loose connections and replace damaged hoses.
4. Clean the Drain Pump: Remove the drain pump filter and clean it thoroughly. Check the pump for any obstructions and ensure that it is rotating freely.
5. Contact Customer Support: If the above troubleshooting steps do not resolve the issue, contact Whirlpool customer support for assistance. They can provide further diagnostics and repair options.

By understanding the potential causes and troubleshooting steps outlined above, you can effectively address the flashing light issue on your Whirlpool dishwasher.
