Kitchenaid Dishwasher Not Draining: How to Fix the Issue

1. Drain pump

If your dishwasher doesn’t seem to be draining properly, one possible cause is a faulty drain pump. The drain pump helps expel water from the dishwasher during the draining cycle.

If it’s not working, water can back up into the machine and cause all sorts of problems.

Why does it fail?

Drain pumps can fail for a number of reasons. The most common is simply age and wear and tear.

Over time, the pump can become less effective and eventually stop working altogether. Other causes include blockages in the pump or a problem with the electrical supply.

How to fix it:

Fortunately, replacing a dishwasher drain pump is a relatively simple repair that you can do yourself. Just be sure to unplug the dishwasher before you begin, and follow these steps:

-Remove the dishwasher’s lower access panel. This will give you access to the drain pump.

-Disconnect the wires from the drain pump and remove any clamps or hoses that are attached to it.

-Remove the old drain pump and install the new one in its place.

-Reconnect any hoses or wires that you disconnected and replace the access panel.

-Plug the dishwasher back in and run a test cycle to make sure it’s draining properly.

2. Pump and Motor Assembly

The pump and motor assembly is located at the bottom of your dishwasher. It is responsible for both draining water from your dishwasher and circulating water during the wash cycle. If your dishwasher is not draining properly, the pump and motor assembly may be to blame.

Why does it fail?

The most common reason for the pump and motor assembly to fail is because of a clog. Over time, food particles and grease can build up in the pump, causing it to become clogged.

Another common reason for failure is because of a damaged impeller. The impeller is responsible for circulating water through the dishwasher. If it becomes damaged, it can cause the dishwasher to fail to drain properly.

How do I fix it?

If the pump and motor assembly is the problem, you will need to replace it. This is a relatively easy repair that can be done in about an hour.

Simply unplug your dishwasher, remove the old pump and motor assembly, and install the new one. Be sure to consult your owner’s manual for specific instructions on how to do this.

Have you ever had a dishwasher that wouldn’t drain?

Chances are, it was because of a problem with the pump and motor assembly. This is a relatively easy repair that can be done in about an hour. Simply unplug your dishwasher, remove the old pump and motor assembly, and install the new one.

3. Water Pump Belt

If your dishwasher is not draining, there is a good chance that the water pump belt has come off or broken.

The water pump belt helps to move the water through the dishwasher so that it can be pumped out. If this belt is not working properly, then the dishwasher will not be able to drain properly.

Why does it fail?

There are a few reasons why the water pump belt may come off or break. One reason is that the dishwasher is not level. If the dishwasher is not level, then the water can become trapped in one side of the dishwasher and cause the water pump belt to come off.

Another reason is that the dishwasher needs to be cleaned. If the dishwasher is not cleaned regularly, then the water can become stagnant and cause the water pump belt to break.

How to fix it?

If the water pump belt has come off, then you will need to put it back on. This can be done by unscrewing the dishwasher from its mounting bracket and then removing the dishwasher tub.

Once the dishwasher tub is removed, you will be able to see the water pump belt. Simply put the water pump belt back on and screw the dishwasher back into its mounting bracket.

If the water pump belt has broken, then you will need to replace it.

To fix this, you will need to replace the water pump belt. You can find replacement belts at most hardware stores or online.

Once you have the new belt, simply follow the instructions in your dishwasher’s manual to replace it. With a new belt in place, your dishwasher should be able to drain properly once again.

4. Drain valve

If your dishwasher isn’t draining properly, the first place to check is the drain valve. This is a small valve located near the bottom of the dishwasher that allows water to flow out. If this valve is defective, it can cause your dishwasher not to drain properly.

Why does it fail?

The most common reason for the drain valve to fail is that it gets clogged with debris. This can happen over time as food and other debris build up in the dishwasher. If the drain valve becomes clogged, it won’t be able to open properly and allow water to flow out.

How do you fix it?

If your dishwasher’s drain valve is clogged, you’ll need to clean it out. The best way to do this is to remove the valve and soak it in a solution of vinegar and water.

This will help break down any debris that’s clogging the valve. Once the valve is clean, you can reattach it and your dishwasher should start draining properly.

If your dishwasher’s drain valve is defective, you’ll need to replace it. You can purchase a new drain valve at most hardware stores. Once you have the new valve, simply remove the old one and install the new one in its place. Your dishwasher should then start draining properly.

5. Drain Impeller

The drain impeller is a small, plastic piece with blades that helps to push water through the dishwasher’s drain hose. If the impeller is broken or damaged, it can cause the dishwasher to not drain properly.

Why does it fail?

There are a few reasons why the impeller might fail. The most common reason is that something has gotten caught in the blades, preventing them from turning. Another possibility is that the impeller itself has become damaged or worn out over time.

How to fix it:

If you think that the impeller is the problem, you’ll need to remove it and clean it. First, disconnect the dishwasher from power and water.

Then, remove the hose that leads from the dishwasher to the garbage disposal or sink. Next, use a screwdriver to remove the screws that hold the impeller in place. Finally, clean any debris out of the impeller blades and replace it if necessary.

If the impeller is not the problem, you may need to check the drain hose for blockages. First, disconnect the dishwasher from power and water.

Then, remove the drain hose from the dishwasher and check it for any kinks or blockages. If you find any, clear them out and reattach the hose.

6. Drain Filter

The Drain Filter is located in the bottom of your dishwasher. To clean it, simply remove it and rinse it off with warm water. If your dishwasher has a lot of buildup, you may need to soak it in vinegar or CLR for a few minutes before rinsing.

Why does it fail?

The Drain Filter can become clogged with food and grease, causing your dishwasher to not drain properly.

How often should you clean it?

You should clean the Drain Filter every few months, or as needed.

7. Drain Solenoid Kit

The Kitchenaid dishwasher not draining can be a very frustrating problem. If you have this problem, there is a good chance that it is due to the drain solenoid kit. This is a very simple fix that anyone can do.

Tools Needed:

  • Phillips head screwdriver
  • Flathead screwdriver
  • Wrench
  • Pliers

Instructions:

If your Kitchenaid dishwasher is not draining, the first thing you should check is the drain solenoid kit. This kit is very easy to install and it will fix the problem in most cases. Here are the steps to install the drain solenoid kit:

First, you need to remove the two screws that are holding the dishwasher door in place. Next, you need to remove the dishwasher door.

Once the door is removed, you will see the drain solenoid kit. The kit includes a new drain solenoid and a new gasket.

To install the new drain solenoid, simply remove the old one and replace it with the new one. Make sure that the gasket is in place before you screw the new solenoid in place.

Once the new drain solenoid is in place, you can put the dishwasher door back on and screw it in place. Your dishwasher should now be draining properly.

7. Drain hose

If your dishwasher isn’t draining, the first thing to check is the drain hose. The hose might be clogged, or there might be a problem with the connection.

Why does it fail?

If the dishwasher doesn’t have enough water to reach the pump, it won’t be able to create the suction needed to remove the dirty water. This can happen if the water inlet valve is clogged or not opening properly.

How do you fix it?

If your dishwasher drain hose is clogged, you can try to clear it with a plunger. If that doesn’t work, you may need to replace the hose.

You can also try cleaning the inlet valve. If that doesn’t fix the problem, you may need to replace the valve.

8. Wrong Type of Detergent

If you are using a dishwasher, there is a certain type of detergent that you should use. You might be tempted to save money and use the same dishwashing liquid that you use for hand-washing dishes, but this is a mistake.

Dishwashing liquids are not as effective in dishwashers and can actually cause problems, like leaving a film on your dishes or not rinsing completely. Instead, use a dishwasher-specific detergent that will be more effective and leave your dishes sparkling clean.

Another common problem that can cause your Kitchenaid dishwasher not to drain properly is using too much detergent.

When you use too much detergent, it can actually cause suds to build up in your dishwasher and prevent the water from draining properly. To avoid this, only use the amount of detergent that is recommended by the manufacturer.

9. Garbage disposal

If your Kitchenaid dishwasher is not draining properly, it may be due to a clogged garbage disposal. If the disposer is full of food scraps or other debris, it can cause a blockage that prevents water from flowing through.

To clear the disposer, simply remove any debris and run water through it until the blockage is cleared. You may also need to use a plunger or other tool to remove the blockage.

If your dishwasher still does not drain properly after clearing the disposer, there may be another issue causing the problem. Check the dishwasher’s manual for troubleshooting tips.

10. Air gap

It is a small hole in the counter near the dishwasher. It has a cover that pops off. Mine was full of gunk (food particles, etc) and I had to clean it out.

Why does it fail?

If the air gap becomes clogged, it will cause your dishwasher to not drain properly.

How do you fix it?

Clean it out with a small brush (toothbrush size) and some vinegar. Put the cover back on.

11. Check valve

The check valve allows water to flow in only one direction and prevents the dishwasher from siphoning water out of the tub. If this valve is defective, it may allow water to leak out of the dishwasher.

Why does it fail?

Over time, the check valve may become clogged with debris, preventing it from closing properly.

How to fix it:

To access the check valve, remove the lower kick plate. The check valve is located on the left side of the pump. Inspect the check valve for debris or damage and clean or replace it if necessary.

You can clean the check valve with a toothbrush and white vinegar. First, remove the hose from the valve and then brush any debris away from the opening. Next, pour vinegar into the opening and let it sit for a few minutes. Finally, flush the valve with water and reattach the hose.

If your dishwasher is still not draining properly after cleaning the check valve, you may need to replace it. You can purchase a replacement check valve at most hardware stores. Simply remove the old valve and install the new one in its place. Be sure to follow the manufacturer’s instructions carefully.

12. Check Ball

The check ball is located in the very back of the dishwasher, on the bottom. You will need to remove the lower spray arm and then unscrew the check ball housing to get to it. The check ball itself is clear and made of plastic.

Why does it fail?

The check ball can fail due to a few reasons. The most common reason is that it gets dislodged from its housing and gets stuck in the drain line.

This can happen if you have hard water, as the mineral deposits can build up around the check ball and cause it to become loose. Another reason is that the check ball itself can become worn out and cracked, causing it to leak.

How do you fix it?

If the check ball is dislodged, you will need to remove it from the drain line and put it back in its housing. You may need to use a small wire or a toothpick to help guide it back into place.

If the check ball is cracked or worn out, you will need to replace it. You can find replacement check balls at most hardware stores.

How to prevent it:

The best way to prevent the check ball from failing is to regularly clean the dishwasher and remove any mineral deposits that may build up around it. You should also replace the check ball every few years to ensure that it does not become worn out.

13. Timer

If your dishwasher doesn’t seem to be draining properly, the first thing you should check is the timer. If the timer is not working correctly, it could be causing the dishwasher to not drain properly.

There are a few things that you can do to test whether or not the timer is working correctly. First, you’ll want to make sure that the timer is set for the correct amount of time. If the timer is set for too long, it could be causing the dishwasher to not drain properly.

Next, you’ll want to check to see if the timer is advancing correctly. To do this, you’ll need to start the dishwasher and then open the door. If the timer is not advancing, it’s likely that it’s not working correctly.

If you find that the timer is not working correctly, you’ll need to replace it. You can purchase a new timer from your local appliance store or online.
