Dishwasher 5

If you’ve ever found yourself asking, “Why is my Jenn-Air dishwasher not draining?”, you’re not alone. This is a common issue that many homeowners face. It can be frustrating and inconvenient, but don’t worry – there are several reasons why this might be happening, and many of them are relatively easy to fix.


Your Jenn-Air dishwasher might not be draining due to several reasons such as a clogged drain hose, issues with the garbage disposer, clogged air gap, a faulty drain pump, or improper installation. To troubleshoot, check and clean the drain hose, inspect the garbage disposer and air gap for clogs, examine the drain pump, and look for obstructions in the dishwasher. If the issue persists, consult a professional technician. Regular maintenance can help prevent such drainage issues.

Understanding Your Dishwasher’s Drainage System

Firstly, it’s important to understand how the drainage system in your Jenn-Air dishwasher works. The dishwasher pumps out the used water after the washing and rinsing cycles are completed. The water drains down to the basin, where a pump propels the water out of the dishwasher. This drained water typically goes into the pipes under your sink or into your garbage disposal.

The dishwasher is connected to a drain hose, which links the dishwasher to the sink drain or garbage disposal. The drain hose should be installed correctly, without any kinks or obstructions, for proper drainage.

Common Causes of Drainage Issues

There are several common reasons why a Jenn-Air dishwasher might not drain completely. These include:

  • Clogged Drain Hose: Food particles, debris, and grease can accumulate in the hose, causing blockages.
  • Garbage Disposer Issues: A clogged garbage disposer can prevent the dishwasher from properly draining.
  • Air Gap Issues: The dishwasher air gap allows air in so that the dishwasher can drain without creating a vacuum. If an air gap gets clogged, it can impact the appliance’s ability to drain.
  • Faulty Drain Pump: The drain pump uses an impeller to force water through the drain hose. If the pump motor is not working, the water won’t drain from the dishwasher.
  • Improper Installation: If your dishwasher has not been installed correctly, it can lead to improper draining and water pooling at the bottom of the machine.

Troubleshooting Your Dishwasher

If your Jenn-Air dishwasher is not draining, here are some steps you can take to troubleshoot the issue:

  1. Check the Drain Hose: Remove it from both the dishwasher and the sink drain, and clean it out.
  2. Inspect the Garbage Disposer: Ensure the knockout plug has been removed from the disposer inlet. Also, check for any food or obstructions caught in the garbage disposer and run the disposer to clear the obstruction.
  3. Examine the Air Gap: If your dishwasher has an air gap, check it for any clogs or blockages.
  4. Inspect the Drain Pump: You may need to replace the drain pump if it’s not functioning correctly.
  5. Look for Obstructions in the Dishwasher: Check for any food or obstructions caught in the dishwasher’s drain or filter. Clean the filter if necessary.

When to Seek Professional Help

If you’ve tried these steps and your dishwasher still isn’t draining, it’s best to consult a professional technician for further assistance. Damaged components, such as the drain pump or check valve, can cause drainage problems and require professional help to fix.

Maintaining Your Dishwasher

Regular maintenance can prevent drainage issues in your Jenn-Air dishwasher. Clean the dishwasher interior monthly, ensure the air gap and vent are free from clogs, unclog the drain hose regularly, and use the correct detergent. Also, remove the garbage disposer knockout plug if the dishwasher is connected to a garbage disposer, and check for obstructions in the drain or garbage disposer.

By understanding the common causes of drainage issues and how to troubleshoot them, you can keep your Jenn-Air dishwasher running smoothly and efficiently. Remember, when in doubt, it’s always best to consult a professional.

Frequently Asked Questions

What are signs of a clogged drain hose in my Jenn-Air dishwasher?

Signs of a clogged drain hose may include water not draining completely from the dishwasher, water pooling at the bottom of the dishwasher, or the dishwasher making unusual noises during the drain cycle.

How often should I clean the drain hose of my Jenn-Air dishwasher?

The frequency of cleaning can depend on how heavily you use your dishwasher and the type of food you often wash off your dishes. However, a good rule of thumb is to check and clean your dishwasher’s drain hose every three to six months to prevent clogs and buildup.

Can I use any detergent for my Jenn-Air dishwasher?

It’s recommended to use a detergent specifically made for dishwashers. Regular dish soap can produce too many suds, which can cause the dishwasher to overflow or not drain properly.

What is the role of a garbage disposer in my dishwasher’s drainage system?

If your dishwasher is connected to a garbage disposer, the dishwasher drains water and food particles into the disposer. The disposer then grinds up and eliminates the food waste, allowing the water to flow freely into your home’s drainage system.

How do I know if the drain pump in my Jenn-Air dishwasher is faulty?

If your dishwasher isn’t draining and you’ve ruled out other common causes like a clogged hose or garbage disposer, the drain pump might be the issue. Signs of a faulty drain pump include unusual noises, the dishwasher not draining, or visible damage to the pump. Always consult with a professional if you suspect a faulty drain pump.
