When your KitchenAid dishwasher displays an error code, the first and most crucial step is to consult your owner’s manual. The manual is your definitive resource for understanding what each specific code signifies for your particular model. It will often provide basic troubleshooting steps that you can perform yourself.
General Steps to Clear a KitchenAid Dishwasher Error Code
Before diving into specific error codes, it’s important to understand the fundamental methods for clearing them. Most KitchenAid dishwashers have a built-in reset function, and often, simply performing a power cycle can resolve temporary glitches.
1. Identify the Error Code
The first step, as mentioned, is to note the exact code displayed on your dishwasher’s control panel. Write it down precisely as it appears. Common codes might be a letter followed by a number (e.g., “A2,” “F9”), or a sequence of flashing lights.
2. Consult Your Owner’s Manual
This cannot be stressed enough. Your owner’s manual is your primary guide. Locate the section on error codes or troubleshooting. Find the code you’ve identified and read the explanation and suggested solutions carefully.
3. Perform a Power Cycle (The Universal Fix)
Many minor electronic glitches that trigger error codes can be resolved by resetting the dishwasher’s power. This is often the simplest and most effective first step for a wide range of codes.
- Locate the circuit breaker: Find the circuit breaker panel in your home that controls the kitchen or the dishwasher specifically.
- Turn off the breaker: Flip the breaker for the dishwasher to the “off” position.
- Wait: Leave the breaker off for at least 5 minutes. Some recommend up to 10-15 minutes to ensure all residual power has dissipated. This allows the dishwasher’s internal computer to fully reset.
- Turn the breaker back on: Flip the breaker back to the “on” position.
- Check the display: Turn on the dishwasher. If the error code is gone and the dishwasher powers up normally, the issue was likely a temporary glitch.
4. Check the Door Latch and Seals
A common cause of error codes, particularly those related to cycle completion or leaks, is a faulty door latch or a poorly sealed door.
- Inspect the latch: Ensure the latch mechanism is clean and free of debris. Check for any visible damage.
- Verify door closure: Make sure the door is closing completely and latching securely. Sometimes, food particles or a misaligned rack can prevent a proper seal.
- Examine seals: Inspect the rubber gasket around the door for any tears, cracks, or debris. A compromised seal can lead to leaks, which might trigger an error.
5. Check Water Supply and Drain Hose
Many error codes relate to the dishwasher’s ability to fill with water or drain it effectively.
- Water supply valve: Ensure the hot water supply valve to the dishwasher is fully open. This valve is usually located under the sink.
- Kinked hoses: Inspect the water inlet hose and the drain hose for any kinks or obstructions. Kinks can restrict water flow in or out.
- Clogged drain: If the dishwasher is not draining, the drain hose might be clogged, or the air gap (if you have one) on your sink might be blocked.
Common KitchenAid Dishwasher Error Codes and Their Solutions
While your manual is the ultimate authority, here are some of the most frequently encountered KitchenAid dishwasher error codes and their typical resolutions. Remember to always perform the power cycle first, as it can resolve many of these issues.
Error Code A0 or A2: Water Fill Issues
These codes generally indicate a problem with the dishwasher not filling with enough water or taking too long to fill.
Possible Causes and Solutions:
- Low Water Pressure: Check the water pressure to your home. If it’s generally low, this could be the cause.
- Closed Water Inlet Valve: As mentioned above, ensure the valve under the sink is fully open.
- Kinked Water Inlet Hose: Inspect the hose leading from the valve to the dishwasher for any bends or kinks that restrict flow.
- Clogged Water Inlet Screen: The water inlet valve often has a small screen to filter debris. This can become clogged over time. You may need to turn off the water supply, disconnect the hose from the dishwasher, and clean this screen.
- Faulty Water Inlet Valve: If the above steps don’t resolve the issue, the water inlet valve itself may be faulty and need replacement.
- Issue with the Float Switch or Water Level Sensor: The dishwasher uses a float switch or sensor to detect the water level. If this is stuck or faulty, it might not signal the dishwasher to fill.
Error Code F0, F1, or F9: Drain Issues
These codes typically signal that the dishwasher is not draining properly, or that water is backing up.
Possible Causes and Solutions:
- Clogged Drain Filter: Most KitchenAid dishwashers have a filter at the bottom of the tub to catch food particles. This is the most common culprit for drain issues. Remove and clean it thoroughly.
- Kinked or Obstructed Drain Hose: Check the drain hose for any kinks. Also, ensure it’s not pushed too far into the drainpipe under the sink, which can create a siphoning effect or blockage.
- Blocked Air Gap (if applicable): If your sink has an air gap, remove its cap and clean out any debris.
- Clogged Sink Drain: If the dishwasher is draining into your sink’s plumbing, a clogged sink drain can prevent proper drainage.
- Faulty Drain Pump: The drain pump is responsible for expelling water. If it’s not working, the dishwasher won’t drain. You might hear the pump attempting to run or no sound at all.
- Issue with the Drain Check Valve: This valve prevents water from flowing back into the dishwasher. If it’s stuck or damaged, it can cause drainage problems.
Error Code D0 or D1: Door Latch Issues
These codes usually indicate that the dishwasher’s door is not latching properly or that the door latch mechanism is faulty.

What does it mean when my KitchenAid dishwasher displays an error code?
An error code on your KitchenAid dishwasher is a signal from the appliance’s internal diagnostic system indicating that it has detected a problem. These codes are designed to help you and service technicians pinpoint the source of the malfunction, whether it’s related to water supply, drainage, heating, or a component failure. Understanding the specific code is the first step toward resolving the issue.
These codes act as a shorthand for more complex technical problems. Instead of a vague “something is wrong,” the error code directs attention to a particular area of the dishwasher’s operation. For instance, a code related to water fill might point to a blocked inlet valve or a faulty water level sensor, while a drainage code could indicate a clogged filter or a problem with the drain pump.
How can I find out what a specific KitchenAid dishwasher error code means?
The most reliable way to determine the meaning of a specific KitchenAid dishwasher error code is to consult your owner’s manual. Most manuals include a troubleshooting section that lists common error codes and provides explanations of their causes and recommended solutions. If you no longer have your physical manual, you can typically find a digital version on the KitchenAid website by entering your appliance’s model number.
If the owner’s manual doesn’t provide sufficient detail or if you’re unable to locate it, you can also search online for your specific model number and the error code. Many appliance repair forums and dedicated KitchenAid support websites offer comprehensive lists of error codes and troubleshooting tips from both professionals and other users. Be sure to cross-reference information from multiple sources to ensure accuracy.
What are the most common error codes for KitchenAid dishwashers?
While the specific codes can vary slightly between models and manufacturing years, some error codes are more frequently encountered. Common examples often relate to issues like water filling problems (e.g., an inlet valve not opening), drainage issues (e.g., the pump not draining water effectively), or heating element malfunctions. You might also see codes indicating sensor errors or door latch problems.
These common codes generally point to issues that are either user-serviceable or require a technician’s intervention. For instance, a simple blockage in the filter might trigger a drainage code, which you can often resolve yourself.

Attempting to bypass the code without repair can lead to further damage to the appliance or unsatisfactory cleaning results.
The act of clearing an error code is often a secondary step performed after the issue has been resolved. For example, after you’ve cleaned a clogged filter that was causing a drainage error, you might then perform a reset procedure to clear the code from the display. However, if the underlying issue persists, the error code will likely reappear.
How do I perform a hard reset on my KitchenAid dishwasher to clear an error code?
A hard reset, often referred to as a power cycle, is a common method to clear temporary electronic glitches and some error codes on KitchenAid dishwashers. To perform this, first, disconnect the dishwasher from its power source. This can be done by unplugging the appliance from the wall outlet or, if it’s hardwired, by turning off the circuit breaker that supplies power to the dishwasher.
Leave the dishwasher unplugged or the breaker off for at least 5 to 10 minutes to allow any residual power to dissipate. After the waiting period, restore power by plugging it back in or flipping the circuit breaker back on. Then, attempt to start a cycle or check the display to see if the error code has been cleared. If the code persists, it indicates a more persistent issue that requires further investigation.
When should I call a KitchenAid dishwasher repair technician?
You should consider calling a KitchenAid dishwasher repair technician when the error code persists after you’ve attempted basic troubleshooting steps outlined in your owner’s manual or found online. This includes situations where the error code indicates a component failure, such as a faulty pump, valve, or heating element, which typically requires specialized knowledge and tools to diagnose and repair safely.
Furthermore, if the problem involves electrical components, plumbing beyond simple filter cleaning, or if you’re uncomfortable performing any troubleshooting steps, it’s always best to err on the side of caution and contact a qualified technician. They can accurately diagnose the issue, order the correct parts, and perform the repair efficiently and safely, ensuring your dishwasher operates correctly.
Are there any safety precautions to take before trying to clear an error code?
