Whirlpool Dishwasher Error Codes Troubleshooting Guide

Is your Whirlpool dishwasher flashing error codes like F9E1 and E15?

When your Whirlpool dishwasher starts flashing error codes or blinking lights in strange patterns, it’s trying to communicate with you. These codes are your dishwasher’s language and way of telling you exactly what’s wrong, so you don’t have to guess.

This guide will cover all of the most common Whirlpool dishwasher error codes to help you understand what they are, what causes them, and how to resolve them.

Whirlpool Dishwasher Error Code Categories 

Whirlpool dishwasher error codes typically follow patterns that indicate the type of problem.

• “E” codes generally indicate sensor or electrical issues
• “F” codes often relate to water flow, drainage, or component failures.

Some codes require immediate attention and professional service, while others can be resolved with simple troubleshooting steps.

Water-Related Error Codes

E1 Error Code – Fill Issues

The E1 error indicates problems with water filling the dishwasher. This code commonly appears when the dishwasher cannot properly fill with water during the wash cycle.

Troubleshooting steps

• Check that the water supply valve is fully turned on
• Ensure the drain hose loop is positioned at least 20 inches above the subfloor to prevent siphoning
• Verify the overfill protection float moves freely and isn’t obstructed by debris
• Reset the dishwasher by disconnecting power for one minute

H2O Error Code – Water Supply Problem

The H2O code pauses the cycle when water supply issues are detected. This straightforward error message indicates insufficient water reaching the dishwasher.

Troubleshooting steps

• Confirm the water supply is turned on
• Check for kinks or blockages in the water supply hose
• Once water supply is restored, press start to resume the cycle

F8E4 Error Code – Water Leak Detection

The F8E4 code is a serious error that means the dishwasher has detected water somewhere it shouldn’t be, most likely in the drip tray or base pan.

For newly installed dishwashers:

Troubleshooting steps

• Verify all water supply connections are properly tightened with rubber washers correctly seated
• Ensure the float switch is properly connected and positioned
• Check that the drip tray is empty and properly installed
• Confirm the fill hose is routed correctly out the rear left side

For established units:

Troubleshooting steps

• Empty the drip tray if water is present
• Check for excessive suds from improper detergent use
• Turn off water supply and press Cancel twice to clear the code

Drainage Error Codes

F9E1 Error Code – Drainage Problems

This code indicates the dishwasher cannot properly drain water, which can lead to standing water and poor cleaning performance.

Troubleshooting steps

• Reset the dishwasher by cycling power for 30 seconds
• If connected to a garbage disposal, ensure the knockout plug has been removed
• Check for food debris or obstructions in the drain or disposal
• Verify the drain hose isn’t kinked or clogged
• Confirm proper drain hose installation and routing
• Look for excessive suds from incorrect detergent use

F9E2 Error Code – Secondary Drainage Issue

Similar to F9E1, this code relates to drainage problems but may indicate a different sensor or component failure.

Troubleshooting steps

• Remove garbage disposal knockout plug if applicable
• Clear drain and disposal obstructions
• Check drain hose for kinks or improper installation
• Ensure correct hose routing within the dishwasher frame

Control and System Error Codes

E3, E6, E7 Error Codes – Control System Issues

These codes typically indicate problems with the dishwasher’s electronic control system or internal sensors.

Troubleshooting steps

• Power cycle the dishwasher by disconnecting it from power for one minute
• If the dishwasher is plugged in, simply unplug and reconnect
• For hardwired units, turn the circuit breaker off and on
• If the error persists after power cycling, professional service is likely needed

F1E1 Error Code – Serious System Fault

This code indicates a significant system problem that requires immediate attention and will prevent normal operation.

Emergency protocol

• The drain sequence will begin, but normal operation stops
• Turn off water supply to the unit if possible
• Press Cancel once to silence the alarm tone
• If water cannot be shut off, do not turn off power and keep the door closed
• Contact professional service immediately

Level and Installation Error Codes

E15 Error Code – Small Leak Detected

The E15 code indicates the dishwasher’s leak detection system has identified a minor water leak.

Immediate action required

• Turn off the water supply to the dishwasher immediately
• Schedule professional service – this typically requires technician diagnosis
• Do not continue operating the dishwasher until repaired

F6E4 Error Code – Leveling Issue

This error occurs when the dishwasher isn’t properly leveled, which can affect the overfill float switch operation.

Troubleshooting steps

• Check that the dishwasher is level from front to back and side to side
• Adjust the dishwasher to level it properly
• Ensure that the way you’ve installed the dishwasher follows the manufacturer specifications correctly

Detergent and Suds-Related Issues

F6E3 Error Code – Excessive Suds Detection

When the dishwasher detects too many suds, it may not operate properly or fill with water adequately.

Troubleshooting steps

• Scoop out visible suds with a plastic cup
• Remove all dishes from the dishwasher
• Add 2-3 tablespoons of vegetable oil to suppress remaining suds
• Run a complete cycle without detergent or dishes
• Follow with another full cycle using proper dishwasher detergent

Prevention

• Only use detergents that are designed to automatic dishwashers
• Make sure to properly replace the rinse aid dispenser cap after filling
• Avoid using excessive amounts of detergent

Advanced Error Codes

F6E1 Error Code – Cycle Inability

This error code means the dishwasher can’t start or resume cycles, but any current running cycles will still be completed.

Troubleshooting steps

• Current cycle continues to completion
• New cycles cannot be started
• Power cycling may resolve the issue
• If error persists, professional service is required

F8E5 Error Code – Critical System Failure

This serious error prevents the dishwasher from working properly, and triggers drainage immediately.

Emergency protocol

• If possible, turn off the water supply ASAP
• Press Cancel once to stop the alarm, and close the door
• Do not turn off power if water cannot be shut off
• If water supply can be controlled, power may be turned off
• Professional service required immediately
