Reading and Understanding Whirlpool Dishwasher Error Codes

Dishwasher error codes can quickly point you toward the cause of a problem so you can restore normal operation sooner. Whether your Whirlpool dishwasher shows a digital code or blinks a sequence of lights, learning how to interpret those signals makes troubleshooting faster and safer. This guide explains what error codes are, how to read and record them, common meanings, steps you can take at home, and when to contact Whirlpool for support. It also focuses on reading and understanding dishwasher error codes in practical, easy-to-follow ways so you can make sense of fault codes Whirlpool dishwasher models may display.

How to Read and Record Error Codes Safely

Digital display models: Most show the code automatically when a fault occurs. If the screen is idle, wake it by pressing a button. The error code will be displayed as a F#E#
Flashing LED models: If the clean light is flashing, this usually an error code communication. Whirlpool dishwashers use a two-part flashing sequence to communicate specific errors. To read the code correctly, look for a distinct pause in the blinking pattern.
- Count the first set of rapid flashes. This is the Function (F) number.
- Watch for a short pause (about 1–2 seconds).\
- Count the second set of rapid flashes. This is the Error (E) number.
- Watch for a longer pause (about 5 seconds) before the entire sequence repeats. Example: If the light flashes 7 times, pauses, flashes 1 time, pauses, and then repeats—that is an F7-E1 error code

Common Dishwasher Error Codes and Their Meanings

Exact codes vary by model, but many Whirlpool dishwashers follow a similar structure (often an F–E format indicating a fault category and subcategory) or use consistent flashing patterns. The categories below offer plain-language explanations to help interpret what you see on the panel. These summaries support reading and understanding dishwasher error codes quickly at home.

Error Code	Potential Concern	Troubleshooting
F8E4	Water Detected in Drip Tray	Empty Drip Tray Ensure Float Switch is Connected Check Water Connections for Leaks
F7E2	Wash Motor Error	Power Cycle, If the error code returns, schedule service.
F9E1	Long Drain - Not Draining	Filter: Remove the filter and clean it thoroughly under running water. Drain Hose: Check for a kinked, pinched, or clogged hose from the back of the dishwasher to the sink. Sink Disposer: If connected, ensure the disposer is clear and that the knockout plug was removed (for new installations). Air Gap: If used, refer to the manufacturer for instructions on removing the cap and clearing blockages.
F6E1	User Interface Error, Main Control	Power Cycle, If the error code returns, schedule service.
H20	Not Detecting Water	Ensure water supply is turned on to the dishwasher. Check to make sure there are no kinks in the water supply hose.

How to Perform a Power Cycle

Much like a computer, resetting the dishwasher control can sometimes solve the issues you are experiencing. To reset the dishwasher control panel, it needs to be disconnected from the power source for 30 seconds. If your dishwasher is plugged into an outlet, simply unplug the unit for 30 seconds and then plug the unit back in. If the dishwasher is hard wired to the power supply, turn the breaker off at the home electrical panel that powers the dishwasher for 30 seconds and then turn the breaker back on.
