KitchenAid dishwashers are some of the best on the market. But like all machines, KitchenAid dishwashers can sometimes have technical issues. These issues sometimes result in a beeping noise coming from the dishwasher.

Some of the reasons your KitchenAid dishwasher is beeping include:

  • The door is not closed correctly
  • There are too many dishes in the dish rack
  • There is not enough detergent in the dishwasher
  • The dishwasher has a low water level
  • The filter is dirty

Why is My KitchenAid Dishwasher Beeping?

KitchenAid dishwashers beep for approximately one minute after finishing a cycle

If you hear a beep and it’s not your dishwasher alerting you of a completed cycle, there are a few things to check.

The Door is Not Closed Correctly

If your dishwasher door is not completely latched, it will trigger a 30-second beeping sequence.

After you load your dishwasher and before you begin the wash cycle, ensure the door is closed completely, correctly, and securely latched shut.

If you are having trouble closing your dishwasher door or cannot get it to latch, make sure all the dish racks are pushed back.

If you still can’t close it, your KitchenAid dishwasher may need repair. If your dishwasher is still under warranty, you’ll likely be able to get it fixed for free.

You Have an Error Code

KitchenAid dishwashers that are experiencing a technical error will beep 15 times consecutively

To find the error code, choose any three buttons on your dishwasher and press them in the same sequence three times

Look up the error code in your dishwasher’s user manual or the KitchenAid website to learn what the problem is and perform the necessary troubleshooting steps to fix it.

There Are Too Many Dishes in the Dish Rack

Another common reason KitchenAid dishwashers beep is that too many dishes are in the dish rack, and they’re blocking the spray arm.

The number of dishes that can fit in a KitchenAid dishwasher varies by model. But, you should always use your best judgment to avoid overloading your dishwasher.

Overloading your dishwasher’s rack can prevent your dishes from getting cleaned properly, lead to additional wear, or even cause permanent damage to the moving parts.

There is Not Enough Detergent in the Dishwasher

If there’s not enough dishwashing liquid in your dishwasher’s detergent cup for it to run, it may start to beep. 

KitchenAid dishwashers need about one tablespoon of detergent per load. Ideally, you’ll fill the cup at least halfway. 

If you forget to put detergent in altogether, you’ll hear a beeping sound.

If you hear this beep even when detergent is in the cup, check to ensure the detergent delivery system is working properly. 

The Filter is Dirty

All KitchenAid dishwashers have a filter located underneath the lowest dish rack.

If your dishwasher’s filter is full of food and other residue, your KitchenAid dishwasher will not work properly. This often leads to a beep. 

It’s generally recommended that you clean your dishwasher’s filter once every six months. If it’s particularly dirty, purchase a replacement filter to ensure smooth running in the future.

There is Not Enough Water

In general, KitchenAid dishwashers use six gallons of water per cycle. If your dishwasher can’t get enough water, it might start beeping.

If your dishwasher is continuously having issues stemming from a low water level:

  • Make sure the water valve is turned on
  • Make sure the water level switch is turned on
  • Check that the drain hose is connected and in good condition

If everything looks good but your KitchenAid dishwasher’s water level is still low, it may need to be repaired.

There Has Been a Power Outage or Surge

All KitchenAid dishwashers need power to run. 

If there is a power surge or outage, your KitchenAid dishwasher will beep once the power is restored to alert you of the issue.

To fix this, press and hold the start button to turn the dishwasher off completely for at least five minutes. Then, turn it back on.

If you believe that your KitchenAid dishwasher has retained permanent damage from a power surge or outage, it is best to contact KitchenAid customer service.

Leaks or Water Accumulation

All KitchenAid dishwashers have an anti-flood component to prevent water from leaking out, and a system to prevent water from filling up at the base. 

If either isn’t working properly, you’ll hear the dishwasher beeping and see a light flashing on the display. 

If your KitchenAid dishwasher beeps three times and flashes a light on the display, it is experiencing a water-related issue. You must replace whatever component is causing the leak before running another cycle. The most common culprits are the anti-flood device and the water valve.
