Troubleshooting Tips for a Frigidaire Dishwasher Not Draining

Having a dishwasher at home can be a convenient and time-saving appliance, but it can be frustrating when it doesn’t function properly. One common issue that many Frigidaire dishwasher owners face is the dishwasher not draining properly. A dishwasher that fails to drain can leave your dishes dirty and wet, and it requires immediate attention to prevent further problems. In this blog post, we will explore some troubleshooting tips to help you tackle the issue of a Frigidaire dishwasher not draining efficiently.

Understanding the Importance of Proper Drainage

Before delving into the troubleshooting tips, it’s crucial to understand why proper drainage is essential for a dishwasher’s performance. The drainage system in a dishwasher is responsible for removing the dirty water from the appliance after each cycle. When the dishwasher doesn’t drain properly, it can lead to standing water in the tub, food residue buildup, and inefficient cleaning. Addressing this issue promptly can save you time, money, and ensure your dishes come out sparkling clean.

Identifying the Problem

When faced with a Frigidaire dishwasher not draining, the first step is to identify the problem. Several factors could contribute to this issue, such as a clogged filter, a blocked drain hose, or a faulty drain pump. By determining the root cause, you can take appropriate action to fix the problem effectively.

Checking the Filter

The dishwasher filter plays a crucial role in preventing debris and food particles from entering the drain pump. Over time, the filter can become clogged, hindering proper drainage. To check the filter, locate it at the bottom of the dishwasher, typically beneath the lower spray arm. Remove any visible debris or residue and rinse the filter under running water. Ensure it is clean before reinstalling it in the dishwasher.

Clearing the Drain Hose

A blocked or kinked drain hose can impede water flow, leading to drainage problems. Inspect the drain hose for any obstructions, such as food particles or foreign objects. If you find any blockages, use a long, flexible brush or a pipe cleaner to gently clear the hose. Ensure the drain hose is properly aligned and not twisted or bent, as this can restrict water flow.

Verifying the Air Gap

An air gap is a device that prevents wastewater from flowing back into the dishwasher. It is usually located on the countertop or sink near the dishwasher. If the air gap is clogged or obstructed, it can cause drainage issues. Remove the air gap cover and clean any debris that may have accumulated. A small brush or toothpick can be helpful for this task. Once cleaned, reassemble the air gap and check if it improves the dishwasher’s drainage.

Examining the Drain Pump

The drain pump is responsible for expelling water from the dishwasher during the drain cycle. A malfunctioning drain pump can prevent proper drainage. To inspect the drain pump, first, disconnect the dishwasher from the power source. Locate the drain pump, which is usually situated at the bottom of the dishwasher. Check for any signs of damage or debris that might be obstructing the pump’s impeller. If you notice any issues, consider consulting a professional technician for further assistance.

Seeking Professional Help

If the aforementioned troubleshooting steps fail to resolve the drainage problem with your Frigidaire dishwasher, it may be time to seek professional help. Experienced technicians have the expertise and tools to diagnose and repair complex issues. Contact Frigidaire’s customer service or consult a certified appliance repair service to ensure a proper resolution.


A Frigidaire dishwasher not draining properly can be a frustrating issue, but with the right troubleshooting steps, you can address the problem and restore your dishwasher’s functionality. By following the steps outlined in this blog post, you can save yourself from the hassle of hand-washing dishes and enjoy the convenience of a fully functional Frigidaire dishwasher.

Remember, when faced with a Frigidaire dishwasher not draining, start by identifying the problem. Check the filter for any debris and clean it thoroughly. Inspect the drain hose for blockages and ensure it is properly aligned. Verify that the air gap is clear and functioning correctly. Lastly, examine the drain pump for any damage or obstructions.
