Reasons Why KitchenAid Dishwasher Not Washing

1. Soap dispenser

The Kitchenaid dishwasher not cleaning soap dispenser is a very common problem. Many people have had this problem and it is usually caused by a buildup of soap scum. There are a few things that you can do to clean out the soap dispenser and get it working again.

First, you will need to remove the dispenser from the dishwasher. This can be done by unscrewing the two screws that hold it in place.

Once the dispenser is removed, you will need to clean out the area where the soap dispenser sits. Be sure to remove any soap scum or debris that may be blocking the opening.

Next, you will need to clean the soap dispenser itself. The best way to do this is to soak it in a mixture of vinegar and water. This will help to break down the soap scum and make it easier to clean. After soaking for a few minutes, you should be able to scrub the soap dispenser with a brush or sponge.

Once you have cleaned the soap dispenser, you will need to reattach it to the dishwasher. Be sure to screw it in place securely so that it does not come loose.

After the soap dispenser is attached, you should test it out by running a cycle with detergent. If the dishwasher still does not clean properly, you may need to replace the soap dispenser.

2. Water Inlet Valve

The water inlet valve is an important part of your dishwasher. It controls the flow of water into the dishwasher. If the water inlet valve is not working properly, it can cause the dishwasher to not clean dishes properly.

Water inlet valves can become clogged with sediment over time. This can cause the valve to not open fully, which can reduce the amount of water that flows into the dishwasher.

Sediment can also cause the valve to leak. If your dishwasher is not cleaning dishes properly, it is a good idea to check the water inlet valve for sediment buildup.

You can clean the sediment out of the water inlet valve with a brush or a toothpick. Be careful not to damage the valve while you are cleaning it. If the sediment is difficult to remove, you may need to replace the water inlet valve.

3. Drain reservoir

One of the most common is a clogged drain reservoir. This can be caused by food, grease, or other debris that gets trapped in the reservoir.

How to fix it?

The first thing you should do is clean out the drain reservoir. You can do this by removing the dishwasher from its position and taking off the panel that covers the reservoir.

Once you have access to the reservoir, you can use a brush or other tool to remove any debris that may be blocking it.

4. Detergent old

If your dishwasher isn’t cleaning dishes as well as it used to, there are several things that could be causing the problem.

One possibility is that the detergent you’re using has gotten old and lost some of its effectiveness.

If you think this might be the case, try switching to a new brand or type of detergent and see if that makes a difference.

5. Water temperature too low

If your water is not hot enough, your dishwasher will not clean your dishes effectively. The water should be at least 120 degrees Fahrenheit to properly clean dishes.

You can check the water temperature with a cooking thermometer. If the water is not hot enough, you will need to contact a plumber to fix the issue.

6. Amount of detergent

If your dishwasher doesn’t seem to be cleaning your dishes as well as it used to, one of the first things you should check is whether you’re using the correct amount of detergent.

Over time, dishwashers can become less effective at cleaning if too much or too little detergent is used.

7. Water Pump Belt

If your KitchenAid dishwasher is not cleaning properly, one possible reason is that the water pump belt has broken or become worn out.

This belt helps to circulate water through the dishwasher during the wash cycle. If it is damaged, the water may not reach all of the dishes and they will not come clean.

To check if the water pump belt is the problem, first make sure that there is water getting to the dishwasher. If there is no water at all, then the issue is most likely with the water pump belt.

To check the belt, remove the dishwasher’s lower access panel and locate the water pump. The belt will be looped around the pulley on the water pump. If the belt is broken, you will need to replace it.

If the belt is not broken, but it is worn out, you may be able to tighten it or adjust it to make it work properly again.

8. Center Wash Arm Assembly

The center wash arm assembly is located under the upper dish rack and sprays water directly onto the dishes in the lower dish rack.

If your KitchenAid dishwasher is not cleaning dishes in the lower dish rack, it may be because the center wash arm assembly is clogged with food or grease.

To clean the center wash arm assembly, remove it from the dishwasher and soak it in a sink full of hot water and dish soap.

Use a toothbrush to scrub away any food or grease that is clinging to the assembly. Rinse the assembly well and reinstall it in the dishwasher. Run a cycle of hot water through the dishwasher to flush out any soap residue.

9. Lower Wash Arm

The lower wash arm of your dishwasher is responsible for spraying water and detergent onto the dishes in the bottom rack.

If your dishes are not getting clean, it could be because the lower wash arm is clogged. Check to see if there is any build-up on the arm and clean it off if necessary.

Why does it fail?

The lower wash arm can become clogged for a number of reasons. Food particles, grease, and detergent can all build up on the arm and cause it to become less effective. Over time, this build-up can harden and make it difficult for water to pass through.

How to prevent it:

You can prevent the lower wash arm from becoming clogged by cleaning it regularly. Depending on how often you use your dishwasher, you may need to clean it once a week or so.

You can clean the lower wash arm with a brush or a toothpick. Be sure to remove any build-up that you see.

10. Lower Wash Arm Assembly

The lower wash arm assembly is located beneath the upper wash arm assembly and is responsible for spraying water and detergent onto the dishes during the washing cycle.

To clean the lower wash arm assembly:

-Remove the lower wash arm assembly by unscrewing it from the bottom of the dishwasher.

-Soak the lower wash arm assembly in a bowl of white vinegar for 30 minutes.

-Rinse the lower wash arm assembly with water and reattach it to the dishwasher.

11. Upper Wash Arm Assembly

It helps circulate water and soap throughout the dishwashing cycle. If this part becomes damaged, it can cause your dishes to come out dirty.

Why does it fail?

There are a few reasons why the upper wash arm assembly might fail. One common reason is blockages.

Over time, debris can build up and cause the holes in the upper wash arm to become blocked. This prevents water from flowing through properly and can leave your dishes dirty.

Another reason this part might fail is because of a broken pump. If the pump that circulates water to the upper wash arm is not working properly, it can cause the upper wash arm to not function correctly.

How do you fix it?

If your upper wash arm assembly is damaged or not working properly, there are a few things you can do to fix it.

One option is to clean the upper wash arm. This can be done by removing it from the dishwasher and using a brush or pipe cleaner to clean out the holes.

Another option is to replace the upper wash arm assembly. This is a more difficult repair and should only be attempted if you are comfortable with doing so.

12. Circulation Pump

The circulation pump is located under the dishwasher. It helps to circulate water throughout the dishwasher and is used to clean the dishes.

If your dishwasher is not cleaning the dishes, it may be due to a problem with the circulation pump. To test the circulation pump, you will need a multimeter.

First, unplug the dishwasher from the power outlet. Then, remove the access panel to the circulation pump. Locate the two wires that go to the circulation pump.

One of these wires will be black and the other will be white. Using your multimeter, test for continuity between these two wires. If there is no continuity, then the circulation pump needs to be replaced.

13. Circulation and Drain Pump Motor

  • Remove the old circulation and drain pump motor.
  • Install the new circulation and drain pump motor.
  • Reconnect the power to your dishwasher and test it out.

14. Pump and Motor Assembly

The KitchenAid dishwasher not cleaning can be caused by a problem with the pump and motor assembly. This is a relatively easy fix that you can do yourself.

First, check to see if there is anything blocking the path of the impeller. If there is, remove it and clean the area thoroughly. Next, check to see if the impeller is damaged. If it is, replace it.

If neither of these solutions solve the problem, then the issue may be with the motor itself. To test this, remove the power supply and check for continuity between the two terminals on the motor. If there is no continuity, then the motor needs to be replaced.

15. Wash Impeller

The wash impeller is a small plastic piece with blades that spins and helps circulate the water during the wash cycle. If your dishwasher isn’t cleaning dishes properly, the wash impeller might be broken or damaged.

To check if the wash impeller is the problem:

-Remove the dishwasher’s lower access panel. This is usually located in the front of the dishwasher, near the floor.

-Locate the wash impeller. It’s a small plastic piece with blades that’s located on the motor shaft.

-If the wash impeller is damaged or broken, you’ll need to replace it.
