When it comes to convenience in the kitchen, few appliances are as essential as a dishwasher. And for those who own a KitchenAid dishwasher, you’re probably accustomed to reliable performance. However, as with any appliance, problems can arise. Whether your dishwasher is leaving dishes dirty, making strange noises, or refusing to start, it’s important to understand what might be going wrong. This guide walks you through common KitchenAid dishwasher problems, their causes, and how to fix them.
Why Isn’t My KitchenAid Dishwasher Cleaning Properly?
One of the most frustrating KitchenAid dishwasher problems you can face is when your KitchenAid dishwasher doesn’t clean your dishes properly. Dirty dishes after a wash cycle are a sign that something isn’t working as it should. Here’s what could be causing the problem and how to address it:
1. Overloading the Dishwasher
While it might seem like a great idea to squeeze in as many dishes as possible, overloading your dishwasher can actually prevent it from cleaning effectively. When too many items are packed in, water and detergent can’t circulate properly, leaving your dishes dirty. To fix this, ensure that dishes are arranged correctly:
- Place large items like pots and pans on the sides.
- Avoid blocking spray arms.
- Allow space between dishes for water and detergent to flow freely.
2. Dirty Spray Arms
The spray arms are responsible for circulating water throughout the dishwasher. If they are clogged with food debris or mineral buildup, the water won’t reach all the dishes. To resolve this, remove the spray arms and clean them thoroughly. Use a small brush or toothpick to remove any blockages from the spray holes.
3. Insufficient Water Temperature
If the water isn’t hot enough, your dishwasher won’t be able to dissolve detergent properly, leaving behind food particles and grime. The ideal water temperature for washing dishes is around 120°F (49°C). If your water temperature is too low, consider adjusting your water heater to reach this temperature, or run hot water in the sink before starting the cycle.
4. Low-Quality Detergent
Using the wrong or low-quality detergent can result in poor cleaning performance. Make sure you’re using a high-quality detergent that’s suitable for your water type. Hard water, in particular, may require special detergents designed to tackle mineral buildup.
5. Faulty Door Seal
A damaged door seal can allow water to leak out during a cycle, affecting the dishwasher’s ability to clean dishes properly. Inspect the door gasket for any visible cracks or wear. If the seal is damaged, you may need to replace it to prevent leaks and ensure better cleaning performance.
KitchenAid Dishwasher Not Draining
Another common issue is when your KitchenAid dishwasher doesn’t drain properly. This problem can leave water standing at the bottom of the machine after the cycle ends. Here’s what could be causing it:
1. Clogged Filter
A clogged filter is one of the most common reasons a dishwasher won’t drain. Food particles and debris can block the filter, preventing proper drainage. To resolve this issue:
- Remove and clean the filter regularly (at least once a month).
- Check for food buildup or mineral deposits that could cause the clog.
2. Blocked Drain Hose
If the drain hose is kinked or clogged, it will prevent water from draining properly. Check the hose for any visible obstructions and straighten any bends that may restrict water flow.
3. Garbage Disposal Clog
In many homes, the dishwasher drains through the garbage disposal. If the disposal is clogged, water won’t be able to flow into the drain. Make sure to clear the disposal and check for any blockages.
4. Faulty Drain Pump
The drain pump is responsible for pushing the water out of the dishwasher. If the pump is malfunctioning, it may need to be replaced. This requires professional assistance, so consider calling an expert if you suspect a faulty pump.
KitchenAid Dishwasher Not Turning On
A dishwasher that won’t turn on can be frustrating, especially when you have a full load waiting to be cleaned. Here’s what you should check:
1. Power Supply Issues
Ensure that your dishwasher is plugged in and that the power cord is intact. A tripped circuit breaker or blown fuse could also be to blame. To check this:
- Unplug the dishwasher and reset the circuit breaker.
- Test the power outlet with another appliance to confirm it’s working.
2. Door Latch Problems
If the door latch isn’t engaging properly, the dishwasher won’t start. Check the door latch to ensure it’s closing securely. If the latch is broken or faulty, it may need to be replaced.
3. Control Lock
Some KitchenAid models feature a control lock to prevent accidental button presses. If the control lock is activated, the dishwasher won’t turn on. To deactivate the lock, refer to the user manual for instructions on how to reset it.
4. Malfunctioning Control Board
A faulty control board can prevent your dishwasher from starting. This is a more complex issue that may require professional repair or replacement of the control board.
Why Is My KitchenAid Dishwasher Not Drying Dishes?
If your dishes are coming out of the dishwasher wet or with water spots, there could be several reasons behind this. Here’s how to fix it:
1. Rinse Aid Usage
Using a rinse aid helps reduce water spots and improves drying performance. If you’re not using a rinse aid, or if the dispenser is empty, consider adding it to improve drying results.
2. Heating Element Problems
The heating element helps to dry the dishes by raising the temperature inside the dishwasher. If the element is broken or malfunctioning, dishes may stay wet. You can check the heating element for any visible damage, but replacing it usually requires professional help.
3. Inadequate Drying Cycle
Ensure that you’re selecting the proper drying cycle for your load. Some cycles use more heat and time to dry, while others may be quicker but less effective. Opt for a longer, more intense drying cycle if your dishes aren’t drying properly.
How to Fix a Leaking KitchenAid Dishwasher
Leaking dishwashers can cause damage to your kitchen floor and cabinets. If your KitchenAid dishwasher is leaking, here’s what to check:
1. Door Seal Inspection
The door gasket or seal is responsible for preventing water from leaking during a cycle. Over time, the seal can wear out or develop cracks. Inspect the gasket for any damage, and if necessary, replace it to stop leaks.
2. Overloading
Overloading the dishwasher can cause water to spill out during the cycle. Make sure you’re not overstuffing the dishwasher, and that dishes are arranged properly to avoid spills.
3. Check for Cracks or Damage
Inspect the dishwasher tub and door for any cracks or damage. A crack in the tub can cause water to leak out. If you find any cracks, the tub may need to be replaced, which is a job best left to professionals.
What to Do When Your KitchenAid Dishwasher Makes Noise
Dishwashers do make some noise during a cycle, but excessive or unusual noises can indicate a problem. Here are the most common reasons for noise:
1. Foreign Objects in the Dishwasher
Check for any foreign objects, like utensils or broken glass, that may have fallen into the dishwasher. These can cause grinding or rattling sounds during the cycle.
2. Loose Spray Arms
If the spray arms are not properly secured, they can make noise while rotating. Make sure the spray arms are attached tightly, and inspect them for any damage.
3. Malfunctioning Motor or Pump
A faulty motor or pump can make loud, grinding noises. If the noise persists and the spray arms are clear, the motor or pump may need to be replaced.
Additional Troubleshooting Tips for KitchenAid Dishwashers
If you’re still facing KitchenAid dishwasher problems after trying the solutions above, here are a few additional tips:
1. Resetting the Dishwasher
Sometimes, a simple reset can fix minor glitches. To reset your KitchenAid dishwasher:
- Turn off the dishwasher and unplug it (or turn off the circuit breaker) for at least 1 minute.
- Plug the dishwasher back in and attempt to start a new cycle.
2. Running the Dishwasher in Diagnostic Mode
Diagnostic mode can help identify specific KitchenAid dishwasher problems. The procedure for entering diagnostic mode may vary depending on the model. Refer to your user manual for the exact steps, and run the diagnostic cycle to check for error codes or malfunctions.
When to Call for Professional Help
If you’ve followed all the troubleshooting steps and your KitchenAid dishwasher is still not working properly, it might be time to call a professional. KitchenAid dishwasher problems like a malfunctioning control board, faulty motor, or a complex plumbing issue require specialized knowledge and parts.

By understanding common issues and knowing how to troubleshoot them, you can save time, money, and frustration. Regular maintenance, like cleaning filters and inspecting seals, will also help ensure your dishwasher continues to perform at its best.
