Common Error Codes and Their Meaning 

When it comes to KitchenAid dishwasher error codes, there are several common ones that you may encounter. It’s important to understand what these codes mean so that you can troubleshoot and fix the issue as quickly as possible. Understanding these codes can help you diagnose and fix the problem, but it’s important to remember that some issues may require professional assistance. If you’re unable to fix the error code on your own, don’t hesitate to contact a professional for help. 

Error Code: 1-1 or F1E1

What it means: 

A relay is stuck on the electronic control board.

What to do: 

Try shutting off power to the appliance for 5 minutes. If the issue persists upon restoring power, it’s time to inspect and repair any damaged wiring connected to the control board. Use your tech sheet as a guide when measuring resistance through all components linked with the board – this can be found behind your machine’s bottom front toe panel. Should you come across any defective parts or wires during the inspection, replace them immediately.

Error Code: 8-1

What it means: 

The dishwasher is not draining properly. It could be due to a clogged drain filter, a blocked drain hose, or a faulty drain pump.

What to do: 

Firstly, check for any blockages in the drain hose or garbage disposal. These areas often become clogged with food particles or other debris over time which can prevent water from flowing freely through your dishwasher. Next, ensure that your dishwasher’s filter is clean and free of any obstructions. A dirty filter will impede proper drainage by preventing water from passing through efficiently.

Error Code: 5-1

What it means: 

The dishwasher’s door latch is not allowing the door to close properly.

What to do: 

Firstly, check the alignment of the door and make sure it is level with the rest of the unit. If this doesn’t work, try adjusting or tightening any screws on both sides of the hinge assembly. Next, check for any damage or wear on either side where they meet at their connection point. If there are signs of damage, such as scratches or dents, replacing these parts may be necessary. 

Lastly, don’t forget about lubrication. A little bit goes a long way when it comes to keeping things moving smoothly. Apply some grease onto all contact points before reassembling everything together again.

Error Code: F6E3

What it means: 

Soap suds have been detected in the dishwasher.

What to do: 

First, start by scooping out as much excess foam as possible using a cup or bowl. Be sure not to use anything sharp that could scratch the interior of your appliance. Next, add one tablespoon of vegetable oil to the bottom of the dishwasher before running another cycle on hot water with no detergent added. This will help break down any remaining bubbles in the system while lubricating its moving parts at the same time. 

Another effective method involves adding vinegar instead – simply pour two cups directly onto the bottom rack during an empty wash cycle (again without any detergent). The acidity helps neutralize alkaline soaps while deodorizing odors too.

Error Code: 3-1 or F3E1

What it means: 

Damage to the thermistor that detects the water temperature or the OWI sensor that detects the amount of debris present in the wash.

What to do: 

Start by unplugging your dishwasher and cutting off the electrical supply. Next, inspect the wiring between the electronic control board and the thermistor/OWI sensor. If you notice any damage or breakage in these wires, get them repaired ASAP. 

In case there are no visible damages in the wiring, consider replacing your thermistor/OWI sensor. This component may be causing issues with the proper functioning of your appliance.

Error Code: 2-1 or F2E1

What it means: 

A button is stuck on the user interface control.

What to do: 

This error code suggests that either the user interface is faulty or the electronic control board is wrongly detecting a stuck button. To troubleshoot your dishwasher, start by ensuring that all buttons on the user interface control are responding. 

If any button fails to work, disconnect the electrical power by unplugging the dishwasher and detach the wire harness of the user interface control. Next, reassemble the door without closing it, and keep the user interface harness disconnected. Now, turn the dishwasher back on, wait 10 seconds for the control board to start, and then close the dishwasher door. 

At this point, your dishwasher will do one of two things. One, your dishwasher will no longer detect a button stuck and will start the drain pump. If this is the case, then the user interface control is faulty and will need to be replaced. 

The other outcome is that the drain pump does not start. This suggests that the problem is the electronic control board which is still detecting a stuck button without the interface control present, in which case it will need to be replaced. 

Error Code: 6-1 or F6E1

What it means: 

The dishwasher is not filling with water.

What to do: 

Check for any obstructions under the overfill float. If this component gets stuck in an upward position, you’ll run into issues with water filling up inside the machine. To avoid potential damage or flooding in your kitchen, take action by unplugging the power and shutting off water supplies before investigating further.

Once disconnected from electrical sources and plumbing lines, inspect the inlet valve screen for blockages that could be preventing adequate water flow through the system. It’s crucial to replace a clogged valve promptly, as debris can cause long-term problems if left unchecked.

What to Do When You Can’t Fix an Error Code 

Sometimes, despite our best efforts, we may be unable to fix an error code on our KitchenAid dishwasher. In such cases, it’s important not to panic or feel defeated. Instead, take a step back and assess the situation. 

Start by checking the user manual for any troubleshooting tips or contact the manufacturer’s customer service for further assistance. If you have exhausted all options and still can’t fix the error code, it may be time to call a professional technician. While this may come at an additional cost, it’s important to remember that error codes suggest your dishwasher needs some attention. Ignoring them may cause further damage to the dishwasher.
