We’ll cover some common reasons and easy steps to help you get your dishwasher back to working like it should. So, let’s dive in and get those dishes cleaned up without any more stress!

Common Causes of Whirlpool Dishwasher Not Draining

If your Whirlpool dishwasher is not draining properly, it can be quite frustrating. Here are some common causes and how you might address them:

1. Clogged Drain Hose

One of the most common reasons for a dishwasher not draining is a clogged drain hose. The hose, which runs from the dishwasher to the drain, can become blocked by food particles or debris. To fix this, you need to check the hose for any visible clogs. Detach the hose from the dishwasher and clean it thoroughly. Reattach the hose and run a cycle to see if the problem is resolved.

2. Blocked Drain Filter

The drain filter is responsible for trapping food particles and preventing them from clogging the drain. If the filter becomes clogged, it can prevent proper drainage. To clean the filter, remove it from the bottom of the dishwasher, rinse it under warm water, and scrub away any debris. Make sure it’s completely dry before placing it back.

3. Faulty Drain Pump

The drain pump helps expel water from the dishwasher. If it’s malfunctioning or damaged, the dishwasher may not drain properly. Listen for unusual noises during the drain cycle, which can indicate a problem with the pump. If you suspect the pump is the issue, you might need to replace it. Consult your dishwasher’s manual for specific instructions or call a professional.

4. Kinked Drain Hose

If the drain hose is kinked or bent, it can restrict the flow of water and prevent drainage. Check the hose for any bends or twists and straighten it out. Ensure that the hose is properly positioned and not obstructed by other items.

5. Broken Check Valve

The check valve prevents water from flowing back into the dishwasher after it has been drained. If this valve is broken or stuck, it can cause drainage issues. Inspect the check valve for any signs of damage or debris. If it’s not working properly, you may need to replace it.

6. Faulty Float Switch

The float switch helps regulate the water level in the dishwasher. If it’s malfunctioning, the dishwasher may not drain correctly. Check the float switch to make sure it moves freely and is not obstructed by debris. If it seems faulty, replacing it might solve the problem.

7. Clogged Air Gap

If your dishwasher has an air gap installed, it helps prevent backflow of water. A clogged air gap can lead to drainage problems. Remove the air gap cover and clean it out. Ensure that there’s no blockage preventing proper drainage.

8. Improper Installation

Sometimes, drainage issues can be traced back to improper installation. Make sure that the dishwasher was installed correctly and that all connections, including the drain hose, are secure and properly positioned.

9. Drain Solenoid Issue

Some dishwashers use a drain solenoid to control the draining process. If the solenoid is malfunctioning, it can prevent the dishwasher from draining. Inspect the solenoid and replace it if it’s not working as it should.

10. Electrical Problems

Finally, electrical issues can also affect drainage. Check for any blown fuses or tripped circuit breakers that might be affecting the dishwasher’s operation. If you suspect electrical problems, it’s best to consult a professional.

Addressing these common causes can help restore proper drainage to your Whirlpool dishwasher and ensure it operates efficiently. If you’re unable to resolve the issue on your own, contacting a professional for further assistance might be necessary.

How to Fix Whirlpool Dishwasher Not Draining

If your Whirlpool dishwasher isn’t draining, here are some simple steps you can follow to fix the problem:

1. Check the Drain Hose

First, you need to check the drain hose. This hose is usually located at the back of the dishwasher. It’s a flexible pipe that connects the dishwasher to your sink’s drain or garbage disposal. To start, make sure the hose is not bent or pinched. If the hose is kinked, water can’t flow through it properly. Carefully straighten out any bends or twists in the hose.

Next, you need to check for blockages. Sometimes food particles or other debris can get stuck inside the hose. To do this, first, turn off the dishwasher and disconnect the hose from the machine. Be prepared for some water to spill out, so have a towel or a small bucket ready.

Once the hose is disconnected, look inside and see if you can spot any clogs. You can use a long brush or a flexible tool to gently clear out any debris. After you’ve cleaned the hose, reconnect it to the dishwasher and make sure it’s securely attached. Turn the dishwasher back on and run a short cycle to see if the water drains properly. If the hose was the problem, this should fix it.

2. Clean the Filter

The next step is to clean the filter. The filter is usually located at the bottom of the dishwasher, so open the dishwasher door and look for a round or rectangular cover. This cover protects the filter from larger food particles and debris. To clean it, first, remove the cover by twisting or lifting it, depending on your dishwasher model. Underneath, you will find the filter.

Take out the filter and rinse it under warm running water. Use your fingers or a soft brush to remove any food particles or debris that might be stuck in it. Be sure to clean both the filter and the area around it.

After cleaning, replace the filter and secure the cover back in place. This helps ensure that water can flow freely through the filter and drain properly. Once you’ve done this, run a short cycle to check if the problem is fixed.

3. Check the Garbage Disposal

If your dishwasher is connected to a garbage disposal, you should check it next. Sometimes, a clog in the garbage disposal can affect the dishwasher’s drainage. Start by making sure the disposal is clear. If it’s not draining properly, it could be causing the issue with your dishwasher.

Turn on the garbage disposal and let it run for a few minutes. This can help clear any blockages that might be causing the problem. If you hear unusual noises or if the disposal isn’t working at all, you may need to clean it or call a plumber.

After running the disposal, go back to your dishwasher and run a short cycle to see if it drains better. If the garbage disposal was clogged, this step might fix the issue.

4. Examine the Drain Pump

The next thing to check is the drain pump. The drain pump helps remove the water from the dishwasher at the end of each cycle. To find it, look at the bottom of the dishwasher, where you will see a cover or panel. Remove the cover to access the pump.

Once you have access to the pump, check it for any blockages. Sometimes, small objects like pieces of broken glass or food scraps can get stuck in the pump. If you find any debris, carefully remove it. Make sure the pump can turn freely and isn’t making any strange noises.

After checking, replace the cover and secure it in place. Turn on the dishwasher and run a cycle to see if it drains properly. If the pump was blocked, this should help fix the problem.

5. Call a Professional

If your dishwasher is still not draining after trying all the above steps, there may be a more serious issue. The problem could be with the drain pump motor, the control panel, or other internal parts. In this case, it’s best to call a professional technician who can diagnose and fix the problem.

A professional will have the tools and experience to handle complex repairs and ensure your dishwasher is working properly. While it can be frustrating, getting expert help can save time and prevent further damage to your appliance.

I hope this guide helps you fix your Whirlpool dishwasher that isn’t draining. By following these steps, you can solve the problem and get your dishwasher working again. If you have any more issues, don’t hesitate to reach out for more help. Happy washing!
