Amana Dishwasher Not Draining: Common Causes and Fixes!

You know how annoying it is when your dishwasher stops working. If your Amana dishwasher is not draining, don’t worry, you’re not alone. This problem happens to many people and can be fixed without too much trouble. In this blog post, we’ll show you the easy steps to get your Amana dishwasher draining properly again. No need to call a repair person just yet! Let’s dive into the simple fixes you can try at home to solve the problem.

Common Causes of Amana Dishwasher Not Draining

1. Clogged Drain Hose

A common reason your Amana dishwasher might not be draining is a clogged drain hose. Over time, food particles, grease, and soap scum can build up in the hose, blocking the water flow. To check if this is the issue, you can disconnect the hose and look for any obstructions. If you find any blockages, you can clean the hose with a long brush or run water through it to clear the debris. Regularly cleaning the drain hose can help prevent future clogs and keep your dishwasher draining properly.

2. Blocked Garbage Disposal

Another possible cause is a blocked garbage disposal. If your dishwasher is connected to a garbage disposal, make sure it is not clogged. A clogged garbage disposal can prevent the dishwasher from draining correctly. You can check the disposal by running it to clear any blockages. Additionally, ensure the knockout plug is removed if the dishwasher is newly installed. This small plastic piece can block the drainage if not removed. Keeping your garbage disposal clear will help your dishwasher drain efficiently.

3. Faulty Drain Pump

The drain pump is responsible for pumping out the water from the dishwasher. If the pump is faulty, the dishwasher will not drain properly. You can listen for a humming noise when the dishwasher is supposed to be draining. If you hear the noise but the water is not draining, the pump might be malfunctioning. In this case, you might need to replace the drain pump. Consulting the user manual or a professional technician can help you with this process.

4. Dirty Filter

A dirty filter can also cause drainage problems. The filter traps food particles and debris to prevent them from clogging the drain hose. However, if the filter itself gets clogged, it can restrict water flow. To fix this, you can remove the filter from the bottom of the dishwasher and rinse it under running water to remove any debris. Regularly cleaning the filter can help maintain proper drainage and improve the overall performance of your dishwasher.

5. Check Valve Issue

The check valve in your dishwasher prevents dirty water from flowing back into the dishwasher. If the check valve is stuck or malfunctioning, it can cause drainage issues. You can locate the check valve at the bottom of the dishwasher and inspect it for any obstructions or damage. If the valve is stuck, you can try to clean it or replace it if necessary. Ensuring the check valve is working correctly can help your dishwasher drain more effectively.

6. Air Gap Blockage

If your dishwasher has an air gap, it can sometimes get blocked and cause drainage problems. The air gap is a small device that prevents backflow and is usually located on the sink or countertop. If water is coming out of the air gap, it might be blocked. You can remove the air gap cover and clean any debris inside. Keeping the air gap clear can help ensure proper drainage and prevent water from backing up into the dishwasher.

7. Problem with the Timer or Control Board

The timer or control board regulates the dishwasher’s cycles, including the draining process. If there is an issue with these components, it can prevent the dishwasher from draining. You might notice the dishwasher stopping mid-cycle or not completing the draining cycle. In such cases, you might need to replace the timer or control board. It is advisable to consult the user manual or a professional technician to diagnose and fix the problem accurately.

By checking these common causes, you can identify and fix the issue with your Amana dishwasher not draining. Regular maintenance and cleaning can also help prevent future drainage problems, ensuring your dishwasher runs smoothly.

The Ultimate Guide to Fix Your Amana Dishwasher That is Not Draining

1. Check and Clean the Drain Hose

When your Amana dishwasher does not drain, one of the first things to check is the drain hose. This hose helps move the water out of the dishwasher and into your sink’s drain or garbage disposal. Sometimes, food bits and other debris can get stuck in the hose, causing a blockage. Here is how to check and clean it:

First, make sure the dishwasher is off and unplugged. Safety is important, so do not skip this step. The drain hose is usually found under the sink or behind the dishwasher. You might need to move some things to get to it.

Once you find the hose, you will see it is connected with a clamp. Use pliers to loosen this clamp so you can take the hose off. Be gentle to avoid breaking anything. Now, look inside the hose. You might see food bits or soap buildup. This can stop the water from flowing out properly.

To clean the hose, you can use a long brush, like a bottle brush. Push the brush through the hose to clear out any debris. Another way to clean it is by running water through the hose. Hold one end under the faucet and let the water flow through. This will help push out any clogs.

After cleaning, reconnect the hose and tighten the clamp with your pliers. Make sure it is secure but do not over-tighten. Now, plug the dishwasher back in and run a short cycle to see if the water drains properly.

Regularly cleaning the drain hose can help prevent clogs in the future. It is a good habit to check it every few months. If the hose is damaged or very dirty, you might need to replace it. You can find replacement hoses at most hardware stores or online.

2. Clear the Garbage Disposal

If your dishwasher is connected to a garbage disposal, it might not drain if the disposal is clogged. A garbage disposal can get blocked by food scraps and other debris, which can affect the dishwasher’s ability to drain. Here is how to clear the garbage disposal:

First, turn off the power to the garbage disposal. This is very important to avoid accidents. You can usually do this by unplugging it or turning off the switch under the sink. Make sure it is completely off before you start.

Next, check if the garbage disposal is clogged. You can do this by looking inside with a flashlight. Be careful not to stick your hand inside. If you see any food scraps or debris, you can use a long spoon or tongs to remove them. Sometimes, turning the disposal with an Allen wrench (usually at the bottom of the unit) can help dislodge any stuck items.

After clearing any visible debris, run the disposal with some cold water. This helps wash away any remaining bits and ensures the disposal is clear. If you have not used the disposal in a while, you might need to run it for a bit longer to clear everything out.

Additionally, if your dishwasher is newly installed, there might be a small plastic piece called a knockout plug inside the disposal inlet. This plug must be removed for the dishwasher to drain properly. Use a screwdriver to pop it out if it is still there.

Once the garbage disposal is clear, you can check if the dishwasher drains properly. Run a short cycle to see if the water is moving out as it should. If the problem persists, you might need to check other parts of the dishwasher, but clearing the garbage disposal often solves the issue.

3. Inspect and Clean the Filter

Another important step in fixing a dishwasher that does not drain is checking and cleaning the filter. The filter traps food particles and debris to prevent them from clogging the drain hose. If the filter is dirty, it can block water flow. Here is how to inspect and clean it:

First, turn off the dishwasher and unplug it. This ensures you can work safely. Then, remove the bottom rack of the dishwasher to access the filter. The filter is usually located at the bottom of the dishwasher tub.

To remove the filter, you might need to twist or pull it, depending on your dishwasher model. Check your user manual if you are unsure how to take it out. Once you have the filter out, rinse it under running water. Use a soft brush, like an old toothbrush, to gently scrub away any food particles or debris stuck in the filter. Be thorough but gentle to avoid damaging the filter.

If the filter is very dirty, you can soak it in warm, soapy water for a few minutes before scrubbing it. This helps loosen any stubborn debris. After cleaning, rinse the filter well to remove all soap and debris.

Reinstall the filter by placing it back in its position and securing it. Make sure it fits snugly and is locked in place. This ensures it will work properly and not come loose during a wash cycle.

Regularly cleaning the filter can help maintain proper drainage and improve the overall performance of your dishwasher. It is a good idea to check and clean the filter every month or so, depending on how often you use your dishwasher.

A clean filter helps the dishwasher drain efficiently and prevents other problems like bad odors or poor cleaning performance. By taking a few minutes to clean the filter regularly, you can keep your dishwasher running smoothly and avoid more significant issues.

4. Check the Drain Pump

The drain pump in your dishwasher is crucial for pumping out water. If it is not working correctly, your dishwasher will not drain. Here is how to check the drain pump:

First, turn off the power to the dishwasher and unplug it. Safety is essential, so make sure there is no electricity running to the appliance while you work on it.

Next, access the drain pump. You might need to remove the bottom panel of the dishwasher to get to it. The drain pump is usually located at the bottom of the dishwasher. Check your user manual for the exact location and how to remove the panel.

Once you have access to the pump, inspect it for any visible damage or obstructions. Look for broken parts, loose wires, or anything that seems out of place. Sometimes, small pieces of food or debris can get stuck in the pump, preventing it from working correctly.

To check if the pump is getting power, you can use a multimeter. This tool measures electrical current and can help you see if the pump is receiving power. If the pump is getting power but not working, it might be faulty and need to be replaced.

If you find that the drain pump is damaged or not working, you might need to replace it. You can buy a replacement pump online or at a hardware store. Follow the instructions in the user manual or consult a professional technician to replace the pump. Make sure to reconnect any wires and secure the pump properly.

After replacing the pump, plug the dishwasher back in and run a short cycle to see if the water drains. A working drain pump should efficiently remove the water from the dishwasher.

Regularly checking the drain pump can help prevent drainage problems. If you notice any strange noises or if the dishwasher is not draining properly, it might be time to inspect the pump. Keeping the pump in good condition ensures your dishwasher works smoothly and drains correctly.

5. Clean the Air Gap

If your dishwasher has an air gap, it can sometimes get blocked and cause drainage problems. An air gap is a small device that prevents dirty water from flowing back into the dishwasher. Here is how to clean it:

First, locate the air gap. It is usually on the sink or countertop near the faucet. It looks like a small cylindrical device with a cover.

Remove the cover of the air gap by gently pulling it off. Inside, you will see the air gap opening. Use a flashlight to look inside and check for any debris or blockages.

To clean the air gap, you can use a small brush or a piece of wire to remove any debris inside. Be gentle to avoid damaging the air gap. Sometimes, running water through the air gap can help clear any remaining debris.

After cleaning, put the cover back on the air gap. Make sure it is secure.

To check if the air gap is clear, run a short cycle on your dishwasher. If the water drains properly, the air gap was likely the issue.
