Amana Dishwasher Error Codes: Complete Troubleshooting Guide

Amana dishwashers are the practical, affordable choice for rental properties, apartments, and value-minded homeowners. Built on Whirlpool Corporation's dishwasher platform, Amana ADB series units share the same F#E# diagnostic code system used in Whirlpool and Maytag dishwashers — but with fewer cycle options and a simpler control interface. When your Amana dishwasher flashes an error code, this guide walks you through every possible code, what is causing it, and how to fix it without overpaying.

How Amana Dishwasher Error Codes Work

Amana dishwashers display error codes using the LED indicator lights on the control panel. On models with a digital display, the code appears as an alphanumeric sequence (like F1E1). On models with only status LEDs, the error is communicated through a pattern of blinking lights — for example, the Clean light blinking 7 times pausing then blinking 1 time translates to error code 7-1.

Basic reset procedure for all Amana dishwasher error codes:

1. Press Cancel/Drain to clear the current cycle.
2. Turn off the dishwasher at the circuit breaker for 5 minutes.
3. Restore power and attempt a new cycle.

If the code reappears, use the specific troubleshooting steps below.

Common Amana dishwasher model prefixes: ADB (built-in dishwasher). The ADB1400AMS, ADB1400AGS, and ADB1500ADS are the most common models found in rental and apartment installations.

F1E1 (1-1) — Main Control Board Error

The main electronic control board has detected an internal fault that prevents normal operation.

Common causes:

• Control board component failure
• Steam damage from the drying cycle migrating into the door panel where the board is housed
• Power surge or electrical event
• Corroded connector pins from moisture intrusion

How to fix:

1. Turn off the dishwasher at the circuit breaker for 5 minutes, then restore power.
2. If the code returns, open the door and inspect the control board. On Amana dishwashers, the board is inside the door panel — remove the inner door panel screws to access it.
3. Look for signs of moisture damage, corrosion on connector pins, or visible burn marks on the board.
4. Check the door vent and gasket area — steam escaping during the dry cycle is the leading cause of board damage on Amana and all Whirlpool-family dishwashers.
5. If the board shows damage, it must be replaced. Also repair the vent seal to prevent repeat failure.

Part cost: Main control board costs $120-$220. Professional repair runs $220-$380 total.

F2E1 (2-1) — Stuck Button Error

A button on the control panel is stuck or sending continuous signals to the control board.

Common causes:

• Physically stuck button from food splatter or grease buildup
• Water intrusion into the button membrane from above (on top-control models)
• Failed user interface board

How to fix:

1. Turn off the breaker for 2 minutes.
2. Press each button on the control panel firmly several times to free any stuck key.
3. Clean the control panel with a damp cloth — food and grease splatter are the most common causes.
4. On Amana top-control models (buttons on the top edge of the door), check for water dripping onto the button area from the countertop above.
5. If cleaning does not resolve the issue, the UI board behind the panel needs replacement.

Part cost: User interface assembly costs $50-$120. Professional repair runs $120-$220 total.

F3E1 (3-1) — Thermistor / Water Temperature Sensor Error

The water temperature sensor (thermistor) or the optical water indicator (OWI) turbidity sensor is sending abnormal readings to the control board.

Common causes:

• Failed thermistor (shorted or open circuit)
• OWI turbidity sensor lens coated with food debris or hard water scale
• Disconnected sensor wire harness
• Sensor damaged by extremely hot water

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 mineral deposits coat the optical lens over time, especially in Sacramento and Bay Area homes. A dirty lens causes the dishwasher to run extremely long cycles because it thinks the water is still dirty.
3. Disconnect the sensor and measure thermistor resistance: approximately 55,000 ohms at room temperature (77 degrees F). Readings significantly higher or lower indicate failure.
4. Check the sensor wire harness for corrosion or loose connections.
5. Replace the sensor assembly if readings are out of range or if cleaning the OWI lens does not resolve the issue.

Part cost: Thermistor/OWI sensor assembly costs $30-$60. Professional repair runs $130-$230 total. Always try cleaning the OWI lens first — it resolves about half of F3E1 codes.

F6E1 (6-1) — Water Inlet Valve Error

The dishwasher is not filling with water or is filling too slowly.

Common causes:

• Water supply valve under the sink not fully open
• Clogged inlet valve screen (very common with hard water)
• Failed water inlet valve solenoid
• Low household water pressure (below 20 PSI)
• No 120V reaching the valve during the fill cycle (control board issue)

How to fix:

1. Check that the water supply valve under the sink is fully open.
2. Turn off the water supply, disconnect the supply line at the dishwasher inlet valve, and inspect the screen. Hard water minerals clog these screens within 3-5 years.
3. Clean the screen or replace the entire valve if calcified internally.
4. Test the inlet valve solenoid with a multimeter: the coil should read 500-1,500 ohms.
5. During a fill cycle, test for 120V AC at the valve terminals. No voltage means the control board is not sending the fill signal.

Part cost: Water inlet valve costs $25-$50. Professional repair runs $120-$220 total. For homes with hard water, an inline sediment filter extends valve life.

F6E4 (6-4) — Flow Meter Error

The flow meter that measures water volume entering the tub is not sending signals or is sending incorrect data.

Common causes:

• Hard water deposits on the flow meter turbine wheel
• Failed flow meter sensor
• Debris blocking the turbine from spinning
• Corroded or loose connector

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 — reseat firmly.
3. Inspect the flow meter for debris that could block the internal turbine wheel.
4. Test the flow meter: it should produce a pulsing signal when water flows through it. Use a multimeter on AC voltage mode.
5. If the turbine is clear and connected but not producing a signal, replace the flow meter.

Part cost: Flow meter sensor costs $25-$50. Professional repair runs $120-$210 total.

F8E1 (8-1) — Slow Drain Error

The dishwasher is not draining water within the expected time after the wash or rinse cycle.

Common causes:

• Clogged filter basket at the bottom of the tub (the most common cause)
• Kinked drain hose under the sink
• Garbage disposal knockout plug not removed (if connected to a disposal)
• Failed drain pump motor
• Food debris in the drain pump impeller area

How to fix:

1. Remove and clean the filter basket at the bottom of the tub. On Amana ADB models, twist the filter counterclockwise and lift it out. Rinse under running water.
2. Check the drain hose under the sink for kinks, especially at the garbage disposal connection.
3. If connected to a garbage disposal, verify the knockout plug inside the disposal inlet was removed during installation. This is the most overlooked cause of F8E1 on all Whirlpool-family dishwashers.
4. Run the garbage disposal to clear any shared drain blockage.
5. If the filter is clean and the hose is clear, check the drain pump. If it hums but does not drain, the impeller may be broken.

Part cost: Filter cleaning is free. Drain pump costs $30-$60. Professional repair runs $120-$230 total.

F8E4 (8-4) — Water Supply Error

The dishwasher detected insufficient water during the wash cycle. This triggers when water level drops during operation rather than during initial fill.

Common causes:

• Water supply interrupted mid-cycle
• Inlet valve sticking intermittently
• Pressure switch or flow meter sending incorrect readings
• Small leak allowing water to escape during the cycle

How to fix:

1. Verify the water supply valve is fully open and was not accidentally bumped.
2. Check under the dishwasher for signs of a leak — wet floor, drip marks on the inlet hose or tub.
3. Inspect the inlet valve for intermittent operation.
4. Check the door gasket for leaks — water escaping past the door reduces tub water level.

Part cost: Door gasket costs $25-$50. Inlet valve costs $25-$50. Professional repair runs $120-$230 total.

F9E1 (9-1) — Diverter Motor Error

The diverter motor that directs water between the upper and lower spray arms is not functioning correctly.

Common causes:

• Failed diverter motor
• Food particles jamming the diverter disc
• Disconnected motor wire harness
• Worn diverter disc or seal

How to fix:

1. Run a diagnostic cycle and listen for the diverter motor — it should make a subtle clicking or rotating sound as it alternates between spray arms.
2. If the motor hums but does not rotate, food particles may be jamming the diverter disc. Disassembly and cleaning sometimes restores function.
3. Check the wiring harness from the diverter motor to the main control board.
4. If the motor does not respond during diagnostic mode, replace the diverter motor assembly.

Part cost: Diverter motor assembly costs $40-$70. Professional repair runs $140-$250 total.

Symptom clue: If top rack dishes come out dirty while the bottom rack is clean, a failed diverter motor is the most likely cause.

FAE1 (10-1) — Detergent Dispenser Error

The detergent dispenser mechanism is not operating correctly.

Common causes:

• Caked-on old detergent physically blocking the dispenser door
• Failed dispenser wax motor or solenoid
• Broken dispenser door latch mechanism
• Control board not sending the dispenser release signal

How to fix:

1. Inspect the detergent dispenser cup and door. Old caked-on detergent is the most common cause — it physically prevents the door from opening.
2. Soak the dispenser area with hot water and white vinegar to dissolve hardened residue.
3. Test the dispenser manually in diagnostic mode. Listen for a click at the dispenser.
4. If the latch is clean but the door does not open, the dispenser actuator motor needs replacement.

Part cost: Dispenser assembly costs $30-$60. Professional repair runs $120-$210 total. Try vinegar soak first — resolves about 40% of dispenser codes.

Amana Dishwasher Diagnostic Mode

Amana dishwashers support a service diagnostic mode:

1. Entering diagnostic mode: With the door closed, press a specific button sequence within a 6-second window. The most common sequence on Amana ADB models is: press any three buttons in sequence 1-2-3, 1-2-3, 1-2-3 (three times). Check the tech sheet for your model's exact buttons.
2. Test cycle: Once in diagnostic mode, the dishwasher runs through each component: fill valve, wash motor, drain pump, heater, dispenser, and diverter.
3. Error history: Displays the last stored error code.
4. Manual control: Advance through steps by pressing Start, or let the full sequence run automatically.

Frequently Asked Questions

Q: How do I reset my Amana dishwasher? A: Press Cancel/Drain, then turn off the circuit breaker for 5 minutes. Restore power and start a new cycle. Most codes clear after the underlying issue is resolved and a complete cycle runs successfully.

Q: Why is my Amana dishwasher not cleaning dishes well? A: Most common causes: dirty filter (clean monthly), hard water buildup on spray arm nozzles (soak in vinegar), low water temperature (should be 120 degrees F at the tap), and coated OWI sensor. Regular maintenance prevents most cleaning problems.

Q: How long do Amana dishwashers last? A: Typically 8-12 years. Lower purchase price and inexpensive repair parts make them a good value. Regular filter cleaning and monthly dishwasher cleaner cycles extend lifespan.

Q: My Amana dishwasher has standing water in the bottom. Is this normal? A: A small amount covering the filter area is normal — it keeps the pump seal lubricated. Water above the filter basket or visible when the door opens indicates a drain problem. Check the filter, drain hose, and garbage disposal knockout plug.

Q: Are Amana dishwasher repairs worth the cost? A: For most repairs, yes. Typical repair costs $120-$250, while a new Amana dishwasher costs $450-$650. The main exception is a wash pump motor replacement ($200-$350 installed) on a unit over 8 years old.

When to Call a Professional

• F1E1 control board failure — Board diagnosis requires electronic testing.
