Whirlpool Dishwasher Error Codes: Complete List with Fixes

Whirlpool dishwashers use the same F/E error code format as other Whirlpool Corporation appliances. On models with a digital display, you will see codes like F6E1 or F8E1. On models with hidden controls (common on KitchenAid and higher-end Whirlpool), error codes display as flashing LED sequences — "1-1" for F1E1, "6-1" for F6E1, etc. Some models alternate between "Clean" light blinks and "Start" light blinks to indicate the two-part code. This guide covers every code for Whirlpool (WDT, WDF) and KitchenAid (KDTE, KDTM) dishwashers with step-by-step repair instructions.

How to Read Whirlpool Dishwasher Error Codes

Digital display models: The F/E code appears directly on the display (F1E1, F6E4, etc.).

Hidden control models (LED indicator lights): Count the number of times the Clean light flashes (first number) and the number of times the Start light flashes (second number). For example: Clean flashes 6 times, Start flashes 1 time = F6E1.

How to enter diagnostic mode:

1. Press any 3 keys in sequence (e.g., High Temp, Heated Dry, High Temp, Heated Dry, High Temp, Heated Dry) — pressing each key within 1 second of the previous.
2. All indicator lights illuminate. The display shows "888" or all segments.
3. Press Start to begin the automatic test cycle.
4. Error codes stored in memory appear during the diagnostic entry.

Basic reset: Turn off the dishwasher at the circuit breaker for 5 minutes, then restore power. Run a Normal cycle. If the code returns, proceed with specific troubleshooting below.

F1E1 (1-1) — Main Control Board Error

The main electronic control board has an internal failure. This is the most expensive dishwasher repair and typically requires professional service.

Common causes:

• Steam damage from the drying cycle migrating into the door panel and corroding the board
• Power surge damage (less common than on other appliances due to low power draw)
• Component failure: corroded relay contacts, cracked solder from heat cycling
• Moisture intrusion through a deteriorated door vent seal

How to fix:

1. Turn off the breaker for 5 minutes to reset. If F1E1 clears, monitor for recurrence.
2. Open the inner door panel (remove screws along the interior edge of the door). Inspect the control board for visible corrosion, burn marks, or green oxidation at connector pins.
3. Check the door vent path for blockages — on Whirlpool WDT and KitchenAid KDTE models, steam from the drying cycle vents through a channel at the top of the door. If blocked, steam condenses and drips onto the control board.
4. If the board shows corrosion at connector pins, moisture intrusion is the root cause. Fix the vent seal to prevent repeat failure, then replace the board (W11305309, $180–$320).

Part cost: Main control board W11305309 costs $180–$320. Professional repair runs $300–$450 total.

F2E1 (2-1) — Stuck Button Error

A button on the control panel is stuck or the user interface assembly is malfunctioning.

Common causes:

• Food splatter and grease seeping behind buttons
• Condensation from drying cycles dripping onto the top-edge controls (top-control models)
• Failed user interface assembly (part W11305311)

How to fix:

1. Turn off the breaker for 2 minutes.
2. Press each button firmly several times to free any physically stuck key.
3. Clean the control panel surface with a damp cloth. On top-control models (where buttons are on the door's top edge), water and condensation are common culprits.
4. If buttons respond intermittently or trigger phantom presses, the UI assembly must be replaced (W11305311, $80–$180).
5. On KitchenAid top-control models, apply a thin bead of clear silicone along the top edge of the membrane after replacement to prevent future moisture intrusion.

Part cost: UI assembly W11305311 costs $80–$180.

F3E1 (3-1) — Thermistor / OWI Sensor Error

The water temperature sensor or the Optical Water Indicator (OWI) turbidity sensor is malfunctioning. The OWI measures how dirty the wash water is to optimize cycle time.

Common causes:

• OWI lens coated with food debris or hard water scale (the most common cause)
• Failed thermistor (part WPW10467289)
• Wiring damage in the sump area from water exposure

How to fix:

1. Clean the OWI lens first. Access the sump area at the bottom of the tub — the OWI is near the wash pump. Clean the lens with vinegar and a soft cloth to remove hard water deposits and food film. This resolves the majority of F3E1 codes.
2. If cleaning doesn't help, disconnect the thermistor and measure resistance: approximately 55,000 ohms at 77 degrees F (25 degrees C). Resistance should decrease as temperature increases.
3. Check wiring from the sensor to the main control board for water damage.
4. Replace the sensor assembly if readings are out of range (WPW10467289, $40–$80).

Part cost: Thermistor/OWI sensor WPW10467289 costs $40–$80.

Diagnostic tip: A dirty OWI lens causes excessively long cycles — the dishwasher keeps washing because it thinks the water is still dirty. If your Normal cycle takes over 3 hours, clean the OWI first.

F6E1 (6-1) — Water Inlet Valve Error

The dishwasher is not receiving water or the flow rate is below the expected threshold.

Common causes:

• Water supply valve under the sink not fully open
• Clogged inlet valve screen from hard water mineral deposits (extremely common in Sacramento)
• Failed inlet valve solenoid (part WPW10195049)
• Low household water pressure (below 20 PSI)

How to fix:

1. Verify the water supply valve under the kitchen sink is fully open.
2. Check the water supply line for kinks.
3. Turn off the water supply, disconnect the supply line at the inlet valve, and inspect the screen. Sacramento and Bay Area hard water calcifies inlet valve screens within 3–5 years. Unlike washer inlet screens, dishwasher valve screens are often molded into the valve body and cannot be effectively cleaned — replacement is usually necessary.
4. Test the inlet valve solenoid with a multimeter: 500–1500 ohms across the coil. Check for 120V AC at the valve terminals during the fill cycle — no voltage means a control board issue, not a valve problem.
5. Consider installing an inline sediment filter on the supply line ($15–$25) to extend valve life in hard water areas.

Part cost: Water inlet valve WPW10195049 costs $35–$70. Supply line connector W10872255 costs $10–$20.

F6E4 (6-4) — Flow Meter Error

The flow meter that measures the volume of water entering the tub is malfunctioning. The dishwasher may overfill or underfill.

Common causes:

• Hard water deposits on the internal turbine wheel (primary failure mode)
• Debris blocking the turbine inside the flow meter
• Failed flow meter sensor (part WPW10467290)
• Corroded connector pins from water exposure

How to fix:

1. Locate the flow meter on the inlet side of the wash system.
2. Check the connector for corrosion or loose pins.
3. Attempt to clear hard water deposits by running a hot vinegar flush: place 2 cups of white vinegar in a dishwasher-safe bowl on the bottom rack and run a Normal cycle with no dishes or detergent.
4. If the flow meter has an accessible turbine, inspect for debris blocking rotation.
5. Test the flow meter output: it should produce a pulsing signal when water flows through it. Use a multimeter on AC voltage mode.
6. Replace the sensor if cleaning doesn't restore function (WPW10467290, $35–$65).

Part cost: Flow meter sensor WPW10467290 costs $35–$65.

F8E1 (8-1) — Slow Drain Error

The dishwasher could not drain the water within the expected time. This is one of the most common dishwasher codes and is usually DIY-fixable.

Common causes:

• Clogged dishwasher filter at the bottom of the tub
• Garbage disposal knockout plug not removed (the most overlooked cause during installation)
• Kinked drain hose under the sink
• Food debris blocking the drain pump impeller
• Shared drain blockage with the kitchen sink

How to fix:

1. Remove and clean the filter. Twist the cylindrical filter at the bottom of the tub counterclockwise to remove. Rinse under running water and use a soft brush to remove trapped food particles. This filter should be cleaned weekly for optimal performance.
2. Check the garbage disposal knockout plug. When a new disposal is installed, the installer must punch out the dishwasher drain inlet plug inside the disposal. If this wasn't done, water cannot drain from the dishwasher. Look inside the disposal inlet (with the power OFF and unplugged) with a flashlight.
3. Inspect the drain hose under the sink for kinks, especially at the disposal or air gap connection.
4. Run the garbage disposal to clear any shared drain blockage — food backed up in the disposal prevents the dishwasher from draining.
5. Check the drain pump: Remove the filter and sump cover to access the pump impeller. Clear any food debris, glass shards, or small objects blocking it.

Part cost: Drain pump WPW10730972 costs $30–$65. Drain hose kit W10906535 costs $15–$30. Filter replacement varies by model ($10–$25).

F9E1 (9-1) — Diverter Motor Error

The diverter motor that alternates water pressure between upper and lower spray arms has failed. Typically, only the bottom rack gets clean while top rack items remain dirty.

Common causes:

• Failed diverter motor assembly (part WPW10537869)
• Food particles jamming the diverter disc
• Seized motor from hard water mineral deposits
• Wiring damage from water exposure in the sump area

How to fix:

1. Run diagnostic mode and select the diverter motor test to verify operation.
2. Listen for the motor during a wash cycle — a humming sound without corresponding movement means the motor is seized.
3. On KitchenAid KDTM models, food particles can jam the diverter disc. Sometimes disassembly and cleaning restores function without replacing parts.
4. Check the wiring harness from the diverter motor to the main control board for water damage.
5. Replace the diverter motor assembly if it doesn't respond (WPW10537869, $50–$90).

Part cost: Diverter motor assembly WPW10537869 costs $50–$90. Diverter motor gasket W10854427 costs $5–$10.

Diagnostic tip: If the top rack dishes are consistently dirty while the bottom rack cleans well, suspect the diverter motor even if no error code is displayed. The motor may be partially functional — working intermittently or only directing water to the lower arm.

FAE1 (10-1) — Detergent Dispenser Error

The detergent dispenser door mechanism has failed. Detergent is not being released during the wash cycle.

Common causes:

• Old caked-on detergent physically blocking the dispenser door from opening
• Failed wax motor actuator in the dispenser (identical design to the washer door lock actuator)
• Warped dispenser latch from hot water and steam
• Wiring issue between the dispenser and control board

How to fix:

1. Clean the dispenser thoroughly. Soak the dispenser area with hot water and white vinegar. Use a toothbrush to remove caked-on detergent from the cup, hinge, and latch mechanism. Old detergent is the most common cause — clean before condemning the motor.
2. Run diagnostic mode and activate the dispenser test. You should hear a click and see the dispenser door spring open.
3. If the dispenser doesn't respond to the test, check the wiring from the dispenser actuator to the control board.
4. If the actuator motor has failed, replace the dispenser assembly (WPW10862260, $40–$80).

Part cost: Dispenser assembly WPW10862260 costs $40–$80. Dispenser actuator motor W10854428 costs $20–$40.

Additional Dishwasher Codes

F5E1 (5-1) — Door Switch Error

The control board cannot detect that the door is latched. The dishwasher will not start.

How to fix: Check the door latch for physical damage. The latch strike (the hook on the door that catches the tub-mounted latch) wears over time. Test the door switch for continuity with a multimeter. Replace the door latch assembly if damaged ($25–$55).

F5E2 (5-2) — Door Lock Error

The door lock mechanism cannot engage. Similar to the washer door lock issue — the wax motor actuator that secures the door during operation has failed.

How to fix: Unplug for 3 minutes to reset. If the lock doesn't engage, the wax motor element is likely spent. Replace the door lock assembly ($30–$60).

FBE1 (11-1) — Wash Motor Error

The main wash pump motor is not running or drawing abnormal current.

How to fix: Check for items blocking the wash pump impeller (glass shards, bones, toothpicks are common). Clear any debris. If the pump hums but doesn't turn, the motor bearings are seized. This is usually a professional-level repair as the wash pump is integrated into the sump assembly ($120–$250).

Dishwasher Maintenance to Prevent Errors

1. Clean the filter weekly. The most impactful maintenance task. Food debris in the filter restricts water flow and causes drain and performance errors.
2. Run a vinegar cleaning cycle monthly. Place 2 cups of white vinegar in a bowl on the bottom rack, run Normal with no dishes. Dissolves hard water deposits on sensors, spray arms, and internal components.
3. Inspect spray arm holes quarterly. Toothpicks and hard water deposits clog the small holes in the spray arms. Use a toothpick to clear each hole.
4. Clean the door gasket monthly. Food debris and mold accumulate in the rubber gasket around the door opening. Wipe with a vinegar-soaked cloth.
5. Check the inlet screen annually. In Sacramento hard water areas, the inlet valve screen clogs within 3–5 years. Proactive inspection prevents fill errors.

Frequently Asked Questions

Q: My Whirlpool dishwasher shows a blinking "Clean" light. What does it mean? A: A blinking Clean light by itself (without counting a pattern) usually indicates the previous cycle did not complete successfully — often due to a drain issue. Run the dishwasher empty on a Normal cycle. If the Clean light blinks again, check the drain filter and the garbage disposal connection. If the light blinks in a counted pattern (e.g., 8 blinks, pause, 1 blink), that represents an error code (F8E1 in this example).

Q: My KitchenAid dishwasher has no display. How do I read error codes? A: KitchenAid dishwashers with hidden controls use LED blink patterns. Count the number of times the Clean LED flashes (this is the F number), then count the Start LED flashes (this is the E number). Clean flashes 6 times + Start flashes 1 time = F6E1 (water inlet valve). Enter diagnostic mode by pressing any 3 buttons in the 1-2-3, 1-2-3, 1-2-3 sequence.

Q: Why does my dishwasher leave a white film on glasses? A: White film is hard water mineral deposits (calcium carbonate). This is extremely common in Sacramento and Bay Area homes. Use a rinse aid (fill the rinse aid dispenser), switch to a detergent with a built-in water softening agent, and run a monthly vinegar cleaning cycle. If the OWI sensor is dirty, the dishwasher may not be washing long enough to dissolve detergent properly.

Q: My dishwasher fills with water but the spray arms don't spin. Which code should appear? A: This points to FBE1 (wash motor) or F9E1 (diverter motor). If neither code appears but the spray arms don't spin, check for items blocking the arms — a tall pot or pan on the bottom rack can prevent arm rotation. Also check that the spray arm retaining nut is tight — they can work loose over time and the arm falls off the spray arm tower.

Q: Can I run my Whirlpool dishwasher without the filter? A: Never. Running without the filter allows food debris to enter the drain pump, potentially destroying the impeller and causing F8E1 drain errors. It also allows debris into the wash pump, where glass shards or bones can damage the impeller seals and cause leaks. Always reinstall the filter after cleaning.

When to Call a Professional

Schedule professional service for these dishwasher issues:

• F1E1 with visible board corrosion — Board replacement plus vent seal repair to prevent recurrence.
• FBE1 (wash motor failure) — The wash pump is integrated into the sump and requires specialized removal.
• Persistent F6E1 after valve replacement — May indicate a control board relay failure rather than a valve issue.
• Water leaking from the base — Could be a pump seal, hose connection, or tub crack. Requires removal of the dishwasher from the cabinet for diagnosis.
• Dishwasher trips the GFCI or breaker — Indicates a ground fault in the wiring or motor that poses a shock hazard.
