Why Is Your Jenn Air Dishwasher Not Draining?

1. Clogged Sump Filters

Jenn Air Dishwashers usually have a course and fine filter to ensure proper water flow and washability.

However, if these filters get clogged, it can result in low water flow and poor wash performance.

Remove and clean the filters using soap, warm water, and a brush to fix this issue.

2. Faulty Drain Pump

The drain pump in your dishwasher is responsible for expelling the water from the appliance.

If the drain pump is malfunctioning, it can cause your dishwasher not to drain.

To determine if it’s the drain pump causing the issue, check for any unusual sounds or issues when the dishwasher is supposed to be draining.

If necessary, you may need to replace the drain pump.

3. Clogged Dishwasher Drain Hose

The dishwasher drain hose can become clogged over time, preventing proper drainage.

To unclog the drain hose, remove it from both the dishwasher and the sink drain, then clean it out carefully.

The drain hose is most commonly clogged near the garbage disposal or dishwasher drain branch tailpiece.

4. Damaged Drain Impeller

The drain impeller is another critical component in your dishwasher’s draining process.

If it’s damaged or broken, it might not be able to direct water through the drain lines effectively.

Inspect the drain impeller for any signs of wear or damage and replace it if necessary.

How To Fix A Jenn Air Dishwasher Not Draining

Here are the best ways to fix a Jenn Air dishwasher not draining.

1. Drain pump and motor assembly

First, check the drain pump and motor assembly.

A faulty or clogged drain pump can prevent the dishwasher from draining properly.

You can inspect the drain pump for any blockages or damage and replace it if necessary.

If the motor assembly is not functioning correctly, it will need to be replaced as well.

2. Thermal fuse

Another component to examine is the thermal fuse.

If the thermal fuse has blown, your Jenn Air dishwasher might not drain.

To fix this issue, you’ll need to replace the thermal fuse.

3. Check the model

It’s essential to know which dishwasher models you have to ensure compatibility with replacement parts.

Remember to refer to your dishwasher’s model number when purchasing parts such as the Dishwasher Chopper Assembly, Dishwasher Pump, Dishwasher Drain Pump, and others.

4. Chopper Assembly

The Dishwasher Chopper Assembly plays a vital role in your dishwasher’s draining process.

Ensure the chopper assembly isn’t clogged or damaged and, if necessary, replace it to improve drainage.

Regularly clean your Jenn Air Dishwasher Filter Assembly to prevent clogging issues.

You can wash the filter using soap, warm water, and a brush.

Additionally, you can run a cycle with white vinegar to help break down any lingering debris and mineral deposits.

5. Check the hose clamp

Inspect the hose clamp to see if it’s loose or damaged.

A leaky hose clamp can lead to drainage issues.

Tighten or replace the hose clamp as needed.

6. The check valve

The check valve is another essential element in preventing water from flowing back into your dishwasher.

If your check valve is not functioning correctly, it might need replacement.

How To Prevent The Problem

To avoid future issues with your Jenn Air Dishwasher not draining, consider implementing the following measures:

1. Regularly clean the drain filter

Ensure you clean the drain filter regularly to prevent the buildup of food particles.

This will help maintain smooth water flow and ensure that the dishwasher can go through its wash cycles without hindrance.

2. Check the drain hose

Make sure the drain hose is not kinked or blocked, as this can restrict water flow during the drain cycle.

Keep the hose elevated and properly secured to prevent it from becoming tangled or caught on any nearby objects.

3. Monitor the air gap

The air gap helps prevent clogs by allowing air to enter the dishwasher during the drain cycle.

It’s essential to clean it regularly to maintain proper water flow.

If you notice a clog, remove the chrome cover and plastic cap, then clear out any debris.

4. Maintain proper water pressure

Your dishwasher needs adequate water pressure to function correctly during its wash and drain cycles.

Ensure that there’s sufficient water flow from your main water supply by checking for any leaks and making sure that all valves are open.

5. Check your garbage disposer

Ensure that your garbage disposer is not clogged and the drain plug is removed before connecting your dishwasher.

A clogged garbage disposer can cause issues with the drainage of your dishwasher.

If you recently installed the garbage disposer, make sure that you removed the solid plug before connecting the dishwasher drain hose.
