Maytag Dishwasher Error Codes: Complete List with Fixes

Maytag dishwashers are built on the Whirlpool Corporation platform and share the same core diagnostic system, but Maytag models feature unique elements like the Dual Power filtration system, PowerBlast cycle with targeted spray jets, the Fingerprint Resistant stainless steel tub, and a heavier-duty wash motor designed for Maytag's "built to last" positioning. When your Maytag dishwasher flashes an error code, this guide covers exactly what it means and how to fix it — from quick DIY solutions to when you need a professional.

How Maytag Dishwasher Error Codes Work

Maytag dishwashers display error codes in two formats depending on the model:

• Digital display models (MDB8959SKZ, MDB9979SKZ): Alphanumeric codes like F1E1 appear on the LED display.
• LED-only models (MDB4949SKZ, older MDB series): Error codes show as a numbered blink pattern. Count the flashes: the first set = the F number, pause, second set = the E number.

To access diagnostic mode on Maytag dishwashers:

1. Ensure the dishwasher is not running. Close the door.
2. Within 6 seconds, press the following button sequence: Hi Temp Wash, Heated Dry, Hi Temp Wash, Heated Dry.
3. All indicator LEDs will illuminate. The display shows stored error codes.
4. Press Hi Temp Wash to scroll through stored codes.
5. To run the automatic test cycle, press Start. The dishwasher will cycle through fill, wash, drain, and dry sequences automatically.
6. To exit, press Cancel/Drain twice or close the door and wait 5 minutes.

On Maytag models with the top-mounted control panel (MDB8959SKZ), the diagnostic button sequence may differ — consult the tech sheet located on the right side wall of the inner door panel.

Basic reset procedure: Turn off the dishwasher circuit breaker for 5 minutes, then restore power. This clears transient errors. If the code returns after the first wash cycle, the underlying problem requires diagnosis.

F1E1 (1-1) — Main Control Board Error

The main control board has detected an internal fault. This is the most serious dishwasher error code and typically requires board replacement.

Common causes:

• Steam damage to the control board — the #1 cause on Maytag and all Whirlpool Corporation dishwashers. Steam from the heated dry cycle vents upward into the door panel where the board is mounted.
• Power surge damage (common in Sacramento area during summer peak demand)
• Component aging after 7–10 years of service
• Water intrusion around the door vent seal

How to fix:

1. Turn off the circuit breaker for 5 minutes, then restore power. If F1E1 was caused by a transient voltage issue, it will clear.
2. If it persists, open the inner door panel (screws around the perimeter of the inner door) to access the control board.
3. Inspect the board for visible moisture, green corrosion at connector pins, burned traces, or swollen capacitors.
4. Check the door vent area for blockages — on Maytag dishwashers, the heated dry cycle creates significant steam that is directed through a vent channel. If the vent is blocked, steam condenses on the control board.
5. If the board shows corrosion or damage, replace it (W11305309, $180–$320). Fix the vent seal/path simultaneously to prevent repeat failure.

Part cost: Main control board $180–$320. Professional repair $300–$450.

F2E1 (2-1) — Stuck Button Error

The dishwasher detects a continuous signal from one or more control panel buttons.

Common causes:

• Food splatter, grease, or water seeping behind the button membrane on top-control models
• Steam condensation from the dry cycle dripping onto the button panel from above
• Physical damage to the button overlay from scrubbing or impact
• UI board failure from moisture intrusion

How to fix:

1. Turn off the circuit 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 — avoid abrasive cleaners that can damage the membrane.
4. On Maytag top-control dishwashers (controls on the top edge of the door), check for water pooling on the top of the door. The dishwasher door gasket should direct water downward — if the gasket is worn or compressed, water reaches the top-mounted controls.
5. If cleaning does not help, replace the user interface assembly (W11305311, $80–$170).

Part cost: User interface assembly $80–$170. Professional repair $150–$250.

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

The thermistor (temperature sensor) or Optical Water Indicator (OWI) turbidity sensor is reading an abnormal value. The OWI measures how dirty the wash water is and adjusts cycle time accordingly.

Common causes:

• OWI lens coated with hard water deposits or food debris — extremely common in Sacramento and Bay Area homes with hard water
• Failed thermistor (part WPW10467289)
• Wiring damage between the sensor assembly and the main control board
• On Maytag models with Dual Power filtration: food particles that bypass the filter can coat the OWI sensor more quickly than on standard models

How to fix:

1. Locate the thermistor/OWI sensor in the sump area at the bottom of the tub, near the wash pump.
2. Clean the OWI lens with white vinegar and a soft cloth. Hard water scale deposits on the optical window cause the sensor to misread water turbidity — the dishwasher thinks the water is always dirty and runs excessively long cycles.
3. Run a cleaning cycle: place a cup of white vinegar upright on the top rack and run a heavy cycle with no dishes. This dissolves mineral buildup throughout the wash system including the OWI.
4. If cleaning does not restore proper function, disconnect the sensor and measure thermistor resistance: approximately 55,000 ohms at 77F (25C).
5. Replace the sensor assembly (WPW10467289, $30–$60) if readings are out of specification.

Part cost: Thermistor/OWI sensor $30–$60. Professional repair $120–$220.

F6E1 (6-1) — Water Inlet Valve Error

The dishwasher is not filling with water or is filling too slowly. The control board determines the inlet valve is not responding properly.

Common causes:

• Water supply valve under the sink not fully open
• Clogged inlet valve screen — Sacramento hard water calcifies the screen within 3–5 years
• Failed inlet valve solenoid (part WPW10195049)
• Low household water pressure (Maytag requires minimum 20 PSI)
• On Maytag models with the PowerBlast cycle: the PowerBlast feature demands higher water flow. If the inlet valve is partially restricted, normal cycles may work but PowerBlast triggers F6E1

How to fix:

1. Verify the water supply valve under the sink is fully open.
2. Check household water pressure — minimum 20 PSI required. Sacramento and Bay Area water pressure can drop below this during peak usage hours.
3. Turn off the supply valve, disconnect the supply line at the dishwasher inlet valve, and inspect the screen for mineral deposits. Unlike washer inlet screens that are removable, dishwasher inlet 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 — coil should read 500–1,500 ohms. Check for 120V AC at the valve terminals during the fill portion of a cycle — no voltage means the control board is not sending a fill signal.
5. Install an inline sediment filter on the supply line ($10–$15) to extend the life of the new valve in hard water areas.

Part cost: Water inlet valve $35–$70. Inline filter $10–$15. Professional repair $120–$220.

F6E4 (6-4) — Flow Meter Error

The flow meter that measures incoming water volume is not sending a proper signal. The dishwasher cannot determine how much water has entered the tub.

Common causes:

• Hard water deposits on the internal turbine wheel of the flow meter — the turbine stops spinning, so the meter reads zero flow
• Flow meter wiring connector corroded or loose
• Failed flow meter sensor (part WPW10467290)
• Debris from the water supply blocking the turbine

How to fix:

1. Access the flow meter on the inlet side of the wash system.
2. Check the connector for corrosion or loose pins. Clean and reseat.
3. Inspect for debris in the flow meter that could block the turbine wheel.
4. If the flow meter is clear and connected, test the output signal — it should produce a pulsing signal when water flows through it (use a multimeter on AC voltage mode).
5. Replace the flow meter (WPW10467290, $25–$55) if it fails the signal test.

Part cost: Flow meter $25–$55. Professional repair $100–$200.

F8E1 (8-1) — Slow Drain / Drain Error

The dishwasher cannot drain water within the expected time. Standing water remains in the tub after the cycle.

Common causes:

• Clogged dishwasher filter — the most common cause, especially on Maytag models with Dual Power filtration where the two-stage filter catches more debris but needs more frequent cleaning
• Blocked drain hose, especially at the garbage disposal connection
• Garbage disposal knockout plug not removed during installation (the most overlooked cause)
• Failed drain pump (part WPW10730972)
• Kinked drain hose under the sink

How to fix:

1. Remove and clean the dishwasher filter at the bottom of the tub — twist counterclockwise to remove. On Maytag Dual Power filtration models, clean both the upper (fine mesh) and lower (coarse) filter elements. Maytag recommends cleaning these filters monthly.
2. Check the drain hose connection under the sink. If connected to a garbage disposal, ensure the knockout plug inside the disposal inlet was removed during installation. This is the single most common cause of drain issues on newly installed dishwashers.
3. Run the garbage disposal to clear any shared drain blockage.
4. Check the drain hose for kinks — it often gets crimped when pushing the dishwasher back into the cabinet.
5. If all above is clear, the drain pump may have failed. Listen for the pump — a humming sound with no water flow means the impeller is broken. Replace the pump (WPW10730972, $30–$70).

Part cost: Drain pump $30–$70. Professional repair $120–$250.

F9E1 (9-1) — Diverter Motor Error

The diverter motor that directs water between the upper and lower spray arms has failed or is jammed.

Common causes:

• Food particles jamming the diverter disc in the sump assembly
• Failed diverter motor (part WPW10537869)
• Wiring harness between the diverter motor and the main control board damaged
• On Maytag models with PowerBlast: the higher-pressure spray system creates more turbulence in the sump, which can dislodge food particles into the diverter mechanism

How to fix:

1. Enter diagnostic mode and run the diverter motor test to verify whether the motor responds.
2. Listen for the motor — a humming sound without movement indicates a seized motor or jammed diverter disc.
3. Access the sump assembly by removing the lower spray arm and filter assembly. Inspect the diverter disc for food debris or hard water scale.
4. Clean the diverter area thoroughly. On some Maytag models, disassembly and cleaning restores function without needing new parts.
5. If the motor does not respond at all, replace the diverter motor assembly (WPW10537869, $40–$80).

Part cost: Diverter motor $40–$80. Professional repair $130–$260.

FAE1 (10-1) — Detergent Dispenser Error

The detergent dispenser door mechanism failed to open during the wash cycle. Detergent was not released.

Common causes:

• Caked-on detergent physically blocking the dispenser door from opening — the most common cause
• Failed dispenser wax motor/solenoid (part WPW10862260)
• Dispenser door spring or hinge broken
• Control board not sending the release signal at the correct time

How to fix:

1. Inspect the detergent dispenser cup. If old detergent is caked on, soak the dispenser area with hot water and vinegar for 15 minutes, then scrub clean. Old caked-on detergent is the most frequent cause of dispenser failures.
2. Test the dispenser manually: enter diagnostic mode and activate the dispenser test. The door should spring open when the actuator fires.
3. Check the dispenser door hinge and spring for physical damage.
4. If the mechanism is clean but the door does not open during the test, the wax motor actuator has failed. Replace the dispenser assembly (WPW10862260, $40–$80).
5. Prevention: use fresh detergent (pods or liquid, not expired powder), do not overfill the dispenser cup, and wipe the dispenser area clean after loading.

Part cost: Dispenser assembly $40–$80. Professional repair $100–$200.

F7E1 (7-1) — Wash Motor Error

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

Common causes:

• Wash motor seized from food debris or a foreign object (broken glass, toothpick, bones)
• Failed wash motor capacitor (on models with capacitor-start motors)
• Motor winding failure
• Blocked sump preventing water from reaching the pump intake

How to fix:

1. Remove the lower rack, spray arm, and filter assembly. Check the sump area for foreign objects — broken glass, bones, fruit pits, and toothpicks are the most common items that jam the motor impeller.
2. Try rotating the motor impeller by hand (accessible from under the sump cover). It should spin freely. If jammed, clear the obstruction.
3. Listen when starting a cycle — a humming motor that does not pump indicates a seized impeller or failed capacitor. No sound at all suggests a wiring or board issue.
4. If the motor is free but still does not run, test the motor leads for voltage during the wash phase (120V AC expected). No voltage = control board issue. Voltage present but motor does not run = motor failure.

Part cost: Wash motor assembly $100–$200. Professional repair $200–$350.

Additional Quick Reference Codes

• F2E2 (2-2) — UI board communication error. Check ribbon cable between UI and main board.
• F6E2 (6-2) — Water inlet valve stuck open. Shut off water supply immediately if the dishwasher is filling continuously.
• F8E2 (8-2) — Drain pump stuck on. The pump runs continuously. May indicate a water leak sensor activation.
• FAE2 (10-2) — Rinse aid dispenser error. Check the rinse aid reservoir cap and dispensing mechanism.
• Clean light blinking 7 times — On some Maytag models, this pattern indicates a heating element or thermistor fault. Enter diagnostic mode for the specific F/E code.

Maytag Dishwasher Hard Water Tips for Sacramento and Bay Area

Sacramento and Bay Area water is among the hardest in California (15–25 grains per gallon in many areas). Hard water causes calcium and mineral buildup that affects dishwasher performance and triggers error codes:

• F3E1 false triggers: Hard water scale on the OWI sensor causes misreading. Clean the sensor monthly with vinegar.
• F6E1 inlet restriction: The inlet valve screen calcifies. Install an inline sediment filter.
• F8E1 drain issues: Mineral scale narrows the drain passages. Run a monthly vinegar cleaning cycle.
• Cloudy film on dishes: This is mineral deposit, not soap residue. Use a rinse aid (Maytag recommends filling the rinse aid dispenser to level 4 in hard water areas) and a dishwasher cleaner like affresh monthly.

Frequently Asked Questions

Q: How do I reset my Maytag dishwasher after an error code? A: Turn off the circuit breaker for 5 minutes, then restore power. For quick resets on less severe codes, press Cancel/Drain twice, wait 2 minutes, then start a new cycle. Most codes clear after the underlying issue is fixed and a successful cycle completes.

Q: Why does my Maytag dishwasher run for 3+ hours on a normal cycle? A: Excessively long cycles on Maytag dishwashers with the OWI (Optical Water Indicator) sensor are almost always caused by a dirty sensor lens. The OWI measures water clarity to determine when dishes are clean — a fouled lens makes it think the water is always dirty, extending the cycle indefinitely. Clean the OWI lens with vinegar (see F3E1 section above). This single fix resolves 80% of long-cycle complaints.

Q: My Maytag dishwasher is not cleaning the top rack. Is this an error? A: Poor top rack cleaning without an error code usually indicates a failing diverter motor (the F9E1 code may not appear until the motor fails completely). The diverter alternates water pressure between upper and lower spray arms. A partially failed diverter sends most water to the lower arm only. Also check that the upper spray arm is not blocked by tall items on the lower rack.

Q: Does the Maytag Dual Power filtration system require special maintenance? A: Yes — the Dual Power filtration system uses a two-stage filter (coarse + fine mesh) that requires monthly cleaning. Remove the lower rack, twist the filter counterclockwise, and rinse both elements under running water. A clogged filter reduces wash performance, extends cycle times, and can trigger F8E1 drain errors. Maytag recommends cleaning more frequently if you do not pre-rinse dishes.

Q: Are Maytag dishwasher parts the same as Whirlpool and KitchenAid? A: Many internal components (control boards, sensors, pumps, inlet valves) share the same part numbers across Maytag, Whirlpool, and KitchenAid dishwashers since they are manufactured on the same platform. The main differences are in cosmetic parts (door panels, handles, rack designs) and feature-specific components (the Dual Power filter assembly is Maytag-specific). Always verify by model number before ordering parts.

When to Call a Professional

• F1E1 persistent after reset — Control board replacement requires careful handling of the door panel and waterproof connectors. Incorrect reassembly causes steam damage to the new board.
• F6E2 inlet valve stuck open — If the dishwasher fills continuously, shut off the water supply immediately and call a professional. Flooding risk is immediate.
• F7E1 wash motor failure — Motor replacement requires disconnecting the sump assembly and multiple plumbing connections. Incorrect reassembly causes leaks.
• Water on the floor — Any leak from the dishwasher requires professional diagnosis. Leaks can damage flooring, cabinetry, and the subfloor.
• Burning smell from the dishwasher — Disconnect power immediately. This may indicate a failed heating element contacting the plastic tub liner.
