Troubleshooting Guide: Frigidaire Dishwasher Not Draining

Having a dishwasher that refuses to drain can be frustrating, especially when you’re left with a sink full of dirty water and a dishwasher full of unclean dishes. One common issue faced by Frigidaire dishwasher owners is the dishwasher not draining properly. In this blog post, we will explore the possible reasons behind this problem and provide you with a troubleshooting guide to help you resolve it. So, if you’re tired of standing in ankle-deep water while unloading your dishwasher, read on!

Understanding the Importance of Proper Drainage

A dishwasher’s ability to drain water effectively is crucial for its overall functionality. When the dishwasher fails to drain, it can lead to standing water in the tub, which can cause foul odors, mold growth, and unsanitary conditions. Furthermore, dishes may not be properly cleaned resulting.. in wasted time and effort. Therefore, addressing the issue of a Frigidaire dishwasher not draining is essential to ensure the appliance’s optimal performance and maintain a clean kitchen environment.

Check for Clogs in the Drain Hose

The first step in troubleshooting a Frigidaire dishwasher not draining is to inspect the drain hose for any clogs or obstructions. Start by disconnecting the dishwasher from the power supply and locating the drain hose, typically located at the back of the dishwasher. Carefully detach the hose and examine it for debris or blockages. Clean out any accumulated gunk or foreign objects that might be obstructing the water flow. Reattach the hose securely and check if the dishwasher is draining properly.

Examine the Drain Pump and Impeller

Another possible reason for the drainage issue is a malfunctioning drain pump or a broken impeller. The drain pump is responsible for pumping out the water from the dishwasher. Over time, it may get clogged or become defective. To inspect the drain pump, access the dishwasher’s bottom panel and locate the pump. Check for any visible signs of damage or debris in the pump or impeller. Clean out any obstructions and ensure the impeller can rotate freely. If the pump is damaged or the impeller is broken, consider replacing the faulty parts.

Ensure Proper Installation of the Dishwasher

Improper installation can also lead to drainage problems in your Frigidaire dishwasher. Ensure that the dishwasher is installed correctly, with the drain hose properly connected to the sink’s plumbing.. or garbage disposal unit. Check for any kinks or bends in the drain hose that may be impeding the water flow. Additionally, verify that the dishwasher is leveled and securely mounted to avoid any restrictions in the drainage system.

Clean the Air Gap or Garbage Disposal Unit

If your dishwasher is connected to an air gap or a garbage disposal unit, these components may be causing the drainage issue. Start by inspecting the air gap, a small cylindrical device usually mounted on the sink or countertop. Remove the cap and clean out any debris that may have accumulated inside. Similarly, if your dishwasher drains through a garbage disposal unit, ensure it is clear of any food particles or clogs that may be hindering the water flow.


Dealing with a Frigidaire dishwasher not draining can be a frustrating experience, but it’s a problem that can often be resolved with some simple troubleshooting steps. By following.. the guide provided above, you can identify and address the underlying causes of the drainage issue. Remember to check for clogs in the drain hose, inspect the drain pump and impeller, ensure proper installation, and clean the air gap or garbage disposal unit if applicable. By taking these steps, you can restore your dishwasher’s ability to drain effectively and enjoy clean, spotless dishes once again.
