Understanding the Possible Causes

Before we jump into the troubleshooting steps, it’s important to understand the potential reasons behind a Frigidaire dishwasher not draining. Several factors could contribute to this problem, including a clogged drain hose, a faulty drain pump, or a malfunctioning air gap. By identifying the underlying cause, you can take the appropriate actions to fix the issue promptly.

Identifying a Clogged Drain Hose

One common cause of a Frigidaire dishwasher not draining is a clogged drain hose. Over time, debris such as food particles or mineral deposits can accumulate and obstruct the flow of water. To check for a clogged drain hose, start by disconnecting the dishwasher from its power source. Next, locate the drain hose, typically located at the back of the dishwasher. Remove the hose and inspect it for any blockages. If you find any debris, use a pipe cleaner or a long, flexible brush to gently clear the clog.

Assessing the Drain Pump

Another potential culprit behind a dishwasher not draining is a malfunctioning drain pump. The drain pump is responsible for pumping out the water from the dishwasher during the draining cycle. If it’s not functioning correctly, water may remain stagnant in the dishwasher. To investigate the drain pump, you’ll need to access the pump housing, usually located beneath the dishwasher. Refer to your Frigidaire dishwasher’s manual for specific instructions on how to access the pump. Once you’ve located it, check for any visible signs of damage or obstructions. If necessary, clean or replace the drain pump to restore its proper functionality.

Examining the Air Gap

The air gap is a crucial component in a dishwasher’s drainage system. Its purpose is to prevent the dishwasher’s wastewater from flowing back into the clean water supply. If the air gap becomes clogged or blocked, it can impede the dishwasher’s draining process. Begin by locating the air gap, typically installed on the kitchen countertop or sink. Remove the cap and visually inspect the air gap for any debris or buildup. Use a toothpick or a small brush to clear any obstructions. After cleaning, run a quick test cycle to ensure that the dishwasher drains correctly.

Checking the Filter and Garbage Disposal Connection

Sometimes, a Frigidaire dishwasher may not drain due to a blocked filter or a faulty connection to the garbage disposal unit. Begin by checking the dishwasher’s filter, typically located at the bottom of the dishwasher. Remove the filter and rinse it thoroughly to remove any accumulated debris. Additionally, ensure that the dishwasher’s drain hose is properly connected to the garbage disposal unit. If the connection is loose or blocked, water may not be able to flow out effectively.


Dealing with a Frigidaire dishwasher that won’t drain can be a frustrating experience. However, by following the troubleshooting steps outlined in this guide, you’ll be well-equipped to identify and resolve the issue. Remember to check for a clogged drain hose, assess the drain pump, examine the air gap, and inspect the filter and garbage disposal connection. By systematically troubleshooting these areas, you’ll greatly increase your chances of restoring your Frigidaire dishwasher’s optimal draining functionality.
