When your Whirlpool dishwasher starts blinking, it can be a frustrating and puzzling experience. The blinking lights may indicate a minor issue or a more serious problem requiring professional attention. This comprehensive guide will delve into the various reasons why your Whirlpool dishwasher may be blinking and provide step-by-step instructions to resolve the issue.
Common Reasons for Blinking Lights
1. Clogged Drain Filter
A clogged drain filter is one of the most common causes of blinking lights on a Whirlpool dishwasher. Food particles, grease, and other debris can accumulate in the filter, obstructing the flow of water.
2. Faulty Door Latch
A faulty door latch can prevent the dishwasher from starting or completing a cycle. The latch may not be properly engaging, allowing water to leak out or preventing the dishwasher from sensing that the door is closed.
3. Water Inlet Valve Problem
The water inlet valve controls the flow of water into the dishwasher. A faulty valve may not open or close properly, resulting in insufficient water supply or flooding.
4. Control Panel Issues
The control panel houses the electronic components that operate the dishwasher. A malfunctioning control panel can cause the dishwasher to blink or behave erratically.
5. Overfill Protection System Activated
The overfill protection system is designed to prevent flooding in case of a faulty water inlet valve or other issues. If the system is activated, the dishwasher will stop filling and blink.
6. Temperature Sensor Malfunction
The temperature sensor monitors the water temperature inside the dishwasher. A faulty sensor may provide incorrect readings, causing the dishwasher to blink or not heat the water properly.
7. Motor Problems
The motor powers the dishwasher’s operation. A faulty motor may not start or may run intermittently, causing the dishwasher to blink.
Troubleshooting Steps
1. Check for Clogs
- Remove the drain filter and clean it thoroughly.
- Inspect the dishwasher hoses for kinks or blockages.
2. Inspect the Door Latch
- Open and close the dishwasher door several times.
- Check if the latch is engaging properly and if the door is securely closed.
3. Test the Water Inlet Valve
- Turn off the water supply to the dishwasher.
- Disconnect the water inlet hose and check for water flow.
- If water does not flow, replace the valve.
4. Reset the Control Panel
- Unplug the dishwasher from the power outlet.
- Wait 30 seconds and then plug it back in.
- Press the “Start” button to reset the control panel.
5. Check the Overfill Protection System
- Locate the float switch under the dishwasher.
- Lift the float switch to reset the system.
6. Test the Temperature Sensor
- Use a multimeter to measure the resistance of the temperature sensor.
- Compare the reading to the manufacturer’s specifications.
- If the resistance is outside the specified range, replace the sensor.
7. Contact a Professional
If the troubleshooting steps above do not resolve the blinking issue, it is advisable to contact a qualified appliance repair technician.

- Ensure that the dishwasher door is properly closed before starting a cycle.
