By SmartHomeBit Staff •  Updated: 06/06/23 •  20 min read


Amana dishwashers can cause draining issues. These can be due to clogged drain hose, filter, or pump. Grease, food, and other particles can collect over time. Faulty pumps or motors may need replacing. Regular maintenance and cleaning can prevent these issues.

Improper installation or kinks in the hose can also lead to problems. Ensuring it’s properly installed and free from obstruction is key. Repair and diagnosis are essential to stop further damage or safety hazards.

Consumer Reports say dishwashers last nine years. But regular maintenance can help extend their lifespan. Taking preventive measures can help to keep it running efficiently for years.

Understanding Amana Dishwasher Not Draining Issues

Got an Amana dishwasher? Have dirty dishes and standing water? It’s time to troubleshoot! Here are five steps to take:

  1. Inspect the drain hose for blockages or kinks.
  2. Clear debris from the garbage disposal.
  3. Clean the filter — it can clog the drain.
  4. Check the pump’s condition.
  5. If those steps don’t work, call an Amana technician.

To prevent future issues, make sure to not overload the dishwasher, and place the dishes correctly. This lets water reach all surfaces, and helps it drain. Keep your home and kitchen hygienic by attending to dishwasher problems quickly!

Potential Causes of Dishwasher Not Draining

If you’re dealing with a dishwasher that won’t drain, you’re not alone. A clogged drain hose or air gap, a faulty drain pump, or a blocked garbage disposal or sink drain could be the culprit. In this section, we will explore the potential causes of a dishwasher not draining, and what could be the possible solution.

Clogged Drain Hose or Air Gap

Is your Amana dishwasher not draining? It could be for several reasons! A clogged drain hose or air gap can stop water from flowing out, leaving standing water inside.

The dishwasher’s drainage cycle is designed to remove wastewater. The drain hose takes it from the dishwasher to the sink, garbage disposal, or drain line. The air gap ensures no backflow occurs. If food particles or objects are in either of these areas, it creates a blockage. Or, if the hose is damaged or installed wrong, this can also cause a problem.

To solve it, you may need to clean with the right tools and chemicals. But if you can’t clear the blockage, you must replace either the drain hose or the air gap.

So, check both the drain hose and air gap if you experience drainage issues. It could be the cause!

Faulty Drain Pump

An Amana dishwasher not draining? It could be the drain pump. This pump pushes water out during the draining cycle. When it doesn’t work, water collects at the bottom.

Maybe a blockage in the impeller or tubes? Or the motor wore out or failed. Electrical damage is another reason.

Other causes of not draining could be out there. Investigate before replacing parts. If all else fails, replacing the drain pump could fix drainage issues and protect your appliance.

Blocked Garbage Disposal or Sink Drain

Are you having trouble draining your Amana dishwasher? It could be due to blocked garbage disposal or sink drain! Here are 6 simple steps to unclog the frustration:

  1. Disconnect the dishwasher from its power source.
  2. Place a bucket to catch any water when loosening the sink trap.
  3. Loosening the nuts on both ends of the trap with pliers and remove it. Be careful not to lose any components inside.
  4. Inspect for blockages, such as food matter or debris.
  5. Use a thin tool, like a wire hanger or long brush, to remove any blockages without damaging any pipes.
  6. Reassemble the sink trap by securing each nut, turn on the water supply and power, then run another cycle.

If this doesn’t solve the issue call a professional repair service. To prevent future blockages, run hot water before starting the cycle. Don’t put large pieces of food waste down the sink which can cause blockages. Clean the garbage disposal unit and general sinks regularly to prevent drainage issues in the dishwasher!

Solutions for Amana Dishwasher Not Draining

If you’re dealing with an Amana dishwasher that won’t drain, don’t panic! In this section, we’ll provide you with some practical solutions to fix the issue and get your dishwasher running smoothly again. We’ll look at a few different possibilities for why your dishwasher isn’t draining, including problems with:

  1. the drain hose or air gap

Let’s get started!

Cleaning Out the Drain Hose or Air Gap

Having trouble with an Amana dishwasher not draining? Cleaning out the drain hose or air gap might provide a solution. When either of these gets clogged with debris, food particles, or any type of blockage, it can restrict the flow of water. Here’s how to clean them out:

Replacing the Drain Pump

If your Amana dishwasher isn’t draining, the drain pump could be at fault. Replacing it is easy – just follow these steps:

  1. Unplug the power to the dishwasher.
  2. Take out the lower rack.
  3. Locate and remove the pump (usually near the bottom).
  4. Swap the old pump for a new one and put everything back together.

It’s important to check other common causes first, such as a blocked drain hose or air gap, blocked garbage disposal or sink drain, and food/debris in the dishwasher.

Fix these issues quickly to prevent bigger problems.

According to Parts Select, people report faulty drainage in their dishwashers all the time. So, if yours isn’t draining, replacing the drain pump may be the answer. And don’t forget to clear your garbage disposal or sink drain to keep your dishwasher running smoothly.

Clearing the Garbage Disposal or Sink Drain

Proper drainage is key for an efficient Amana dishwasher. Clear any blockage in the garbage disposal or sink to prevent water backing up into the dishwasher. Here’s 5 simple steps to clear the blockage:

  1. Switch off the power to the garbage disposal.
  2. Use tongs or pliers to remove any visible debris.
  3. Pour a cup of baking soda down the disposal, followed by a cup of vinegar. Let it sit for 10 minutes.
  4. Flush with hot water for several minutes.
  5. Turn on the power and check if the dishwasher is draining correctly.

Don’t pour grease or oil down the drain as they can solidify and cause blockages. Clean and maintain both units to prevent drainage issues.

Other details to note: use a plunger to clear stubborn blockages in the garbage disposal. Inspect and clean the dishwasher’s spray arms. Run hot water in the sink before starting a cycle. Scrape off the initial food inside the dishwasher. Clean and maintain the units to prevent pricey repairs and improve performance.

Additional Tips for Maintaining Amana Dishwasher and Preventing Future Issues

To keep your Amana dishwasher working in top condition and avoid future issues, it’s important to follow some simple maintenance tips. In this section, we’ll share some additional tips to help you maintain your dishwasher. We’ll cover topics like checking for food or debris in the dishwasher before running it, running hot water in the sink before starting the dishwasher, and regularly cleaning and maintaining the dishwasher.

Checking for Any Food or Debris in the Dishwasher Before Running It

  1. Examine all dishes and utensils for leftover food or debris.
  2. Remove any visible food particles with a paper towel/scraper.
  3. Check the dishwasher’s bottom for blocking objects and remove them.
  4. Clean out the filter and spray arm with soap and water if dirty.
  5. Run hot water in your kitchen sink before starting your Amana.

These precautions can prevent clogged drains, which can be expensive to repair. Taking care of your Amana will increase its lifespan and enhance performance. So, get your sink hot before starting your Amana for a smooth ride.

Running Hot Water in the Sink Before Starting the Dishwasher

Before you start the dishwasher, it is highly recommended that you run hot water in the sink. This can make a huge difference in the washing and cleaning performance. Hot water loosens any greasy food or oil, which can be drained away.

It preheats the dishwasher, which reduces wear and tear. You may even save energy, as it decreases the time to reheat the dishwasher.

Run hot water in the sink at least once a day. It is a simple way to keep dishes clean and free of contaminants. You may notice an improvement in the overall performance of your dishwasher.

A homeowner with an Amana Dishwasher found that pouring boiling water down the drain and around the garbage disposal before starting the dishwasher increased draining efficiency more than before. So, running hot water in the sink before starting the dishwasher is a great way to keep your dishes clean, kitchen hygienic, and dishwasher running smoothly for a long time.

Regularly Cleaning and Maintaining the Dishwasher

Clean and maintain your dishwasher regularly! This will ensure it functions well for a long time. Food particles, grease, and soap residue can accumulate in the dishwasher’s interior and cause problems if not cleaned. Neglecting maintenance can be costly.

Follow this five-step guide:

  1. Scrape off food from dishes before loading.
  2. Remove visible debris with a damp cloth or sponge.
  3. Check and clean filters for adequate water flow.
  4. Run a hot water cycle with a specialized cleaning solution every few months.
  5. Inspect hoses, pumps, and valves for wear/damage.

Old detergent can cause clogged pipes or drainage issues. Always use fresh detergent and store it in a cool, dry place.

To prevent draining issues on an Amana Dishwasher:

  1. Remove large food debris before loading.
  2. Scrape off food from dishes.
  3. Run hot water through sink tap before washing cycle.
  4. Check drain hose for leaks.
  5. Keep garbage disposal free of food scraps.

Cleaning and maintaining your appliances is much more cost-effective than repairing them, so prioritize frequent cleaning and maintenance! Following these tips will make sure your Amana dishwasher leaves no soggy mess behind.

Common Reasons for Amana Dishwasher Not Draining

Did you know that there could be several reasons why your Amana dishwasher is not draining properly? In this section, we will explore the most common culprits that prevent your dishwasher from draining. From a faulty drain impeller to a blocked garbage disposal or sink drain, we will uncover the reasons why your dishwasher might not be draining as it should. Stay tuned to find out how to address these issues and get your dishwasher back to its optimal performance.

Faulty Drain Impeller

Amana dishwashers not draining? Could be the drain impeller. It’s a vital part of the drainage system that moves water out. If it’s damaged or malfunctioning, water stays in the dishwasher after a cycle. This can cause bad smells and even damage the dishwasher.

To spot the problem, access the pump assembly of the dishwasher. Check for any obstructions or damages. Replace the drain impeller if you see any issues.

Though not common, a faulty drain impeller can still occur. So, factor it in when diagnosing drainage problems. Address it straight away to avoid further issues.

Faulty Check Valve

Owners of Amana dishwashers: Take heed! A faulty check valve may cause your dishwasher to not drain correctly. This valve is vital – it stops dirty water from going back into the dishwasher once it drains. If it’s not working right, water can stay in your dishwasher, leaving your dishes covered in icky water and bad smells in your home.

To prevent this, keep the check valve clean and inspect it often. Signs of damage can be spotted before a full breakdown. Furthermore, use good detergents, keep parts clean, avoid overloading the washer, and you’ll be set.

In short, a broken check valve can be bad news for your Amana dishwasher, but with care, it can be prevented. Plus, cleaning out the drain hose gives you an excellent arm workout!

Blocked Drain Hose

Do you have an Amana dishwasher? If so, you might find the drain hose is blocked. This stops water leaving and reduces the washing performance, as well as risking damage to your appliance.

Here’s how to fix it:

  1. Turn off the power and close the water supply valve.
  2. Find the drain hose and disconnect it from the sink and dishwasher.
  3. Use a wire hanger or plumber’s snake to remove any blockages.
  4. Reconnect the hose and turn on the power and water supply.
  5. Run a cycle to check it’s draining correctly.

Check the drain hose regularly – making sure it’s securely attached. This problem can be annoying – like Sarah experienced. She looked online and fixed it herself using a few steps.

In conclusion, a blocked drain hose can usually be fixed without a professional. With some effort, you can make dishwashing stress-free again.

Clogged Air Gap

Clogged air gaps are a common problem in Amana dishwashers. The air gap is a small device, usually found on top of the sink, which prevents dirty water from flowing back. But when it clogs, it blocks the water from flowing out, causing drainage issues.

To fix it, first check if there is standing water in the kitchen sink. This could be a sign of a clog. Then, use a thin brush or pipe cleaner to clean it out. Sometimes, it might require dismantling and washing all parts to remove any buildup.

Regularly clean and maintain all parts of your dishwasher. Up to 80% of repair calls are because of clogs and drainage problems. Doing regular maintenance will help you avoid these unnecessary calls and keep your dishwasher running smoothly.

Faulty Drain Pump

A faulty drain pump can cause a dishwasher to not drain properly. This is very annoying for homeowners. The drain pump pumps out water from the tub during the drainage cycle. If it’s not working, water will stay in the tub. This leads to standing or murky water.

Several things can cause a malfunctioning drain pump. Such as: damaged motor blades, a clogged or broken impeller, or debris around the motor shaft. If you press the start button and hear no humming sound, it means you need to replace the pump.

It’s important to fix this issue quickly. Inadequate draining can cause stagnant water in the dishwasher. This leads to bacteria and bad odors. Replacing the motor seal or damaged impeller is easy and fast. You just need access to the dishwasher’s lower panel.

Damaged Drain Solenoid

Amana Dishwashers can have drainage problems. Reasons include: clogged hoses, faulty pumps, blocked disposals or sink drains. Another reason could be a damaged drain solenoid.

If this is the case, the valve won’t open correctly and water won’t flow out of the dishwasher. Here’s how to fix it:

  1. Turn off power and unplug the dishwasher.
  2. Find the solenoid – usually in the motor assembly.
  3. Remove wires with pliers.
  4. Unscrew and remove the old solenoid.
  5. Put the new one in and screw it.
  6. Reconnect wires and test.

Checking for issues like broken parts and solenoids will help fix the draining problem. This ensures a full repair is done.

Blocked Garbage Disposal or Sink Drain

A blocked garbage disposal or sink drain could be the reason behind an Amana dishwasher not draining properly. To fix this, follow these 4 steps:

  1. Shut off the power to the dishwasher.
  2. Check the garbage disposal and sink drain for any obstructions. Remove them using the right tools.
  3. Flush the sink drain with hot water for several minutes.
  4. Turn the power back on and run a cycle to check that it drains.

If the issue persists, professional help may be necessary. Remember that some Amana models have a built-in water softener system. This can help avoid mineral buildup and future drainage problems. So, follow these steps and be aware of your specific model’s features for better maintenance. Put an end to your dishwashing woes!
