Causes and Solutions for KitchenAid Dishwasher Error Codes

What are KitchenAid error codes? KitchenAid error codes are codes that tell users the type of problem or malfunction their unit is experiencing.

These codes point you in the right direction and stops you from using the trial-and-error method.

KitchenAid Dishwashers come with different error codes and understanding what they mean and how to fix them will help you clear error codes whenever they appear.

In this section, we’ll be looking at the different types of KitchenAid error codes, what triggers them, and how to fix them.

Error Code: 1-1 or F1E1

  • The F1E2 signals something amiss with the control board’s memory.
  • Let’s try an easy fix first – unplug the machine for 5 minutes to reset things. If that doesn’t do the trick, it’s likely time to swap in a new control board.

Error Code: 1-2 or F1E2

  • When F2E1 pops up, it means one of those buttons is sticking.
  • Give the control panel a gentle scrub to loosen any sticky gunk. Still sticking? Unplug and restart the machine. If no luck, the control board may need replacing.

Error Code: 2-1 or F2E1

  • This error code means that there’s a stuck button on the user interface control.
  • To clear this error code, visually inspect the control for food particles, debris, or any sticky residue that can cause the buttons to stick. Clean the control panel with a soft damp cloth and mild soapy water.
  • If the error persists after cleaning, reset the machine by turning off electrical power for five minutes. Still not working? As a last resort, you should consider replacing your electronic control board.

Error Code: 2-2 or F2E2

  • This sneaky code means the connection between the control board and panel is on the fritz.
  • Let’s try resetting the power first. Next, inspect the wiring harness between them – tighten or replace if needed. If that doesn’t work, replacement time for the control board or panel.

Error Code: 3-1 or F3E1

  • When F3E1 appears, the temperature sensor is misbehaving. Unplug the machine and check the sensor wiring.
  • If it checks out, swapping in a new thermistor or OWI (optical water indicator) sensor should do the trick.

Error Code: 3-2 or F3E2

  • This error code means that there’s a shorted thermistor or OWI sensor.
  • To clear the error code, unplug the dishwasher and check the wiring from the control board to the sensors; if the wiring is fine, replace the faulty thermistor or OWI sensor.

Error Code: 3-3 or F3E3

  • This error code means that the OWI failed to calibrate, or the drain hose check valve has failed, causing dirty water to backflow into the dishwasher.
  • To clear the error code, check if water backs up through the drain hose into the dishwasher tub when disconnected; if so, replace the drain hose check valve.
  • Otherwise enter diagnostic mode – if you see high soil levels, clean and recalibrate the OWI sensor by unplugging, cleaning, and running a calibration cycle – if the error persists after calibration, replace the OWI sensor.

Error Code: 4-4 or F4E4

  • This error code means that there’s a communication error between the electronic control board and the circulation pump motor.
  • To clear the error code, unplug the dishwasher and check the water pump wiring harness for loose/damaged connections – tighten loose wires or replace broken wires.
  • If the wiring checks out, replace the circulation pump/motor assembly; if the error persists, the main control board needs replacing.

Error Code: 5-1 or F5E1

  • This error code means that the door switch has failed. It is caused by not closing the door within 4 seconds of starting a wash cycle or a defective latch.
  • To clear this error code, ensure the door is promptly closed when starting the dishwasher. If the code continues despite this, unplug the dishwasher and disassemble the door to check the door switch wiring harness for loose/damaged connections and replace them.
  • If the harness checks out, you may have to replace the faulty door latch assembly as a last resort.

Error Code: 5-2 or F5E2

  • Code F5E2 means the control board can’t tell if the door opened correctly.
  • Check by opening and closing the door. If the problem continues, unplug and restart the cycle. If that works, the latch likely needs swapping.

Error Code: 6-1 or F6E1

  • When F6E1 strikes, the water supply line is disrupted.
  • Check for debris blocking the overfill float and inspect the water inlet valve screen for clogs. If the screen looks clean, verify water supply, check valve wiring, and replace faulty parts as needed.

Error Code: 6-2 or F6E2

  • This error code means that the water inlet valve in your dishwasher has failed.
  • To clear this error code, unplug the dishwasher and check the valve’s wire harness connections, replace the harness or water supply valve if fault is found.
  • Otherwise, check valve resistance (you should get around 1,400 ohms) – if out of spec, replace the faulty inlet valve, or if the issue persists then the main control board needs replacing.

Error Code: 6-3 or F6E3

  • Excessive suds or low water levels can trigger F6E3.
  • Drain excess suds, ensure proper detergent use, and check that water fills to the normal level. Also inspect for flipped containers holding water back and clean valve screen as needed. If valve or dispenser issue found, replace faulty part.

Error Code: 6-4 or F6E4

  • When F6E4 appears, the overfill float switch stuck open.
  • Check switch operation and clear any debris. Also verify inlet valve shuts off properly when powered down.

Error Code: 6-6 or F6E6

  • This code means the incoming water is too chilly!
  • Use a thermometer to check temperature. If it’s below normal, have the hot water heater adjusted. Otherwise, run a thermistor diagnostic test and replace if needed.

Error Code: 7-1 or F7E1

  • When F7E1 pops up, it indicates the heating element failed.
  • Inspect the element visually and replace if damaged. If it looks good, check element wiring connections and replace any faulty wiring found.

Error Code: 7-2 or F7E2

  • This error code means that the heating element won’t shut or turn off.
  • To clear this error code, try resetting the power (you can do that by turning off power for 5 minutes before turning it on) – if code returns, the control board likely needs replacing.

Error Code: 8-1 or F8E1

  • This pesky code signals a draining issue.
  • Check the drain path for obstructions first and remove any found. If it looks clear, inspect pump wiring and replace any damaged wires. If wiring looks good, replace the faulty drain pump.

Error Code: 8-2 or F8E2

  • This error code means that, the drain pump has encountered an electrical problem.
  • To clear the error code, shut off power to the dishwasher and then shut off water. With power off, check pump wiring and replace any damaged wires. If wiring checks out, pump replacement is needed.

Error Code: 9-1 or F9E1

  • This error code means that the electronic control board in the dishwasher is unable to detect the position of the diverter disk.
  • To clear this error code, unplug the dishwasher and check the wiring harness to the motor for loose/damaged connections; if the wiring checks out, replace the faulty diverter motor since it’s not sending positioning signals.

Error Code: 9-2 or F9E2

  • This error code means that the diverter motor is stuck on. That’s to say that the diverter relay on the electronic control board is defective.
  • To clear this error code, you’ll have to replace the electronic control board.

Error Code: 9-3 or F9E3

  • This error code means that the diverter disc in your machine is damaged or missing.
  • To clear this error code, remove dish racks, turboZone manifold, feed tube and pump outlet to inspect disc. If damaged or missing, replacement is needed.

Error Code: 9-4 or F9E4

  • This error code means that your dishwasher has experienced a lower spray arm error.
  • To clear this error code, check for obstructions blocking the arm and remove if found. Inspect arm motor wiring and replace any damaged wires. If wiring looks good, replace faulty lower spray arm motor.

Error Code: 10-1 or FAE1

  • This error code means that there’s a detergent dispenser error.
  • To clear this error code, Unplug and check wiring between control board and dispenser. Tighten or replace damaged wires if found. Otherwise, the dispenser needs replacing.

Error Code: 10-2 or FAE2

  • This error code indicates a problem, with the connection of the vent wax motor.
  • To resolve this error code begin by disconnecting the dishwasher from power. Open the dishwasher. Inspect the wiring that is connected to the vent wax motor. If you find any damaged wires simply reconnect them securely. Replace them if necessary. If the wiring appears to be in condition it is likely that the vent wax motor itself needs to be replaced.

Error Code: 10-3 or FAE3

  • This error code signifies a malfunction in the drying fan of your machine.
  • To clear this error code start by unplugging the dishwasher and examining the wiring between the control board and drying fan.
  • If you notice any wires gently push them back into place. In case you identify any damaged wires they will require replacement. If everything seems fine with the wiring it is probable that a replacement, for the drying fan is necessary.
