Kitchenaid dishwasher error code

In KitchenAid’s HE (high efficiency), errors appear as a light flashing in specific fashions near the Clean label. Whatever error appears on a machine, its control panel will be off until a solution is found.

First, you will see a function code. After two seconds, a specific code, which refers to a particular problem, will appear. Then there will be a five-second pause, and the whole sequence will repeat.

Control Panel Codes

The first two-function series contains codes, which signal malfunctions in the control panel.

1-1 appears, when the control board detects a problem in the relay, which is installed on the circuit board; 1-2 signals corrupted or damaged memory.

Try resetting the machine: turn it off, wait about five minutes and turn it back on. If the code is still there, most likely, the electronic control panel needs to be replaced.

2-2 indicates a stuck key in the panel; 2-2 signifies total loss of contact between the panel and the control board. If there are no keys that work on the panel, or it has signs of damage, most probably, there is a problem in the control board. It may need to be replaced.

Temperature Sensor Codes

Dishwashers feature a temperature sensor (thermistor), which controls temperature and activates protective functions every time temperature falls behind of or exceeds set values. Any code that contains “3” signals an issue in this component or any part that is closely related to it, for example, an optical water indicator (OWI), which detects debris in water. The user manual should have a paragraph on testing the temperature sensor and related components.

To fix these problems, do the following: cut off power, check the wiring near the thermistor and/or OWI using the manual/repair guide. If the wiring is ok, there is a problem in the thermistor/OWI. Replace it.

The 6-6 code signals that the water entering the machine is not hot enough. First, check it with a thermometer. If it is cooler than 110F, and the water heater is ok, replace the thermistor and OWI, or the control board.

Circulation Pump Monitor Codes

The 4-4 code signals that the circulation pump is down. In some cases, it remains functional, but the system reads it as non-functional. Unplug the machine, check the wiring harness for loose or damaged wires. Fix the loose ones, if any. Replace all damaged parts. If the wiring is all right, but the error is still there, the circulation pump motor needs to be replaced.

Door Switch Codes

There are five error codes signaling door switch issues. The 5-1 code means that the door is not latched well. The 5-2 code appears when the door fails to open.

In the first case, press the Start button and close the door immediately. Unplug the machine and check the latch and its wiring. In the second case, check the components first. If there is no visible damage, but the problem persists, replace the door switch.

Water Inlet Valve Codes

Codes, which start with “6” refer to the water inlet valve and, sometimes, the detergent dispenser.

  • 6-1: Water is not coming in
  • 6-2: The water inlet valve is not getting electricity
  • 6-3: The water pump is blocked by air or suds
  • 6-4: The float switch is open

Check the entire water supply system without missing a single component. There should not be suds in the bottom part of the machine. Not unlikely, some of these components need to be replaced.

Heating Element Codes

This error code appears when the heating element is not functioning properly. Unplug the dishwasher and check the heating element and the wiring for damage. Replace the faulty part.

Also, this error may appear when the heating element fails to shut off. Unplug the machine and wait for 5 minutes. The plug it back in and check if the error has appeared again. If it has, it is an electronic control board error, which may require replacement of the control board.

Drain Pump Codes

Codes with the “8” prefix refer to drain pump problems. For example, 8-1 means that the machine is not draining properly, and 8-2 indicates an electrical problem in the pump. Unplug your machine, check the drain pump and the wiring. If the problem continues, replace the pump.

Diverter and Spray Arm Codes

The 9-1 code indicates that the diverter’s position is uncertain. Disconnect the machine and check the diverter – an element, which forces the water through the spray arms. Also, check the wiring and connections. If these are ok, replace the diverter.

The 9-2 error means that the diverter is on and won’t switch off. The 9-3 code indicates that the diverter disk is not there. The 9-4 error means that the lower spray arm may be obstructed. Replace the arm or the disk.

Kitchenaid dishwasher error code 10

Kitchenaid dishwasher error code 10

Codes starting with “10” refer to electrical components:

  • 10-1: dispenser issues
  • 10-2: vent wax motor issues
  • 10-3: drying fan issues

If you see any of these codes, unplug the machine and check the wiring near the respective component.

Codes for Other Models

In other models, motor malfunctions are indicated by a light flashing near the Light/China label. Issues occurring in electrical components are indicated by this light near the Rinse and/or Normal labels. If you see this happen, it means that the flood switch is activated. Disconnect the machine from the mains and contact your local technical maintenance service.

If the light appears near the Rinse and Heavy labels, the machine is not getting water the way it should be. Check the inlet valve and hoses for blockages and remove them, if any.
