Troubleshooting Guide: Frigidaire Dishwasher Not Draining? Here’s What You Need to Know

A dishwasher is an indispensable appliance in any modern kitchen, designed to make our lives easier by efficiently cleaning and sanitizing our dishes. However, when it comes to convenience, the frustration of a dishwasher not draining can quickly put a damper on your post-meal clean-up routine. If you own a Frigidaire dishwasher and are experiencing drainage issues, don’t fret! In this comprehensive guide, we will walk you through the common causes and troubleshooting steps to get your Frigidaire dishwasher back in perfect working order.

Understanding the Importance of Proper Drainage

Before delving into the troubleshooting process, it’s important to understand the crucial role that proper drainage plays in your Frigidaire dishwasher’s functionality. Efficient drainage ensures that dirty water is effectively removed from the appliance, preventing the redepositing of debris onto your clean dishes. A failure to drain properly not only compromises the cleanliness of your dishes but also puts undue stress on the dishwasher’s components, potentially leading to further damage. With this in mind, let’s explore the reasons behind your Frigidaire dishwasher’s drainage issues.

Clogged Drain Hose:

The drain hose is a crucial component responsible for carrying the wastewater out of your dishwasher. Over time, it can become clogged with food particles, debris, or even mineral deposits. To tackle this issue, start by disconnecting the dishwasher from the power source. Next, locate the drain hose, typically found beneath the dishwasher or connected to the sink’s plumbing. Inspect the hose for any visible clogs or kinks, and gently remove them using a pipe cleaner or a long, flexible brush. Reconnect the hose and test the dishwasher to check if the drainage problem persists.

Blocked Air Gap or Garbage Disposal:

In some setups, dishwashers are connected to an air gap or a garbage disposal unit. These components prevent wastewater from flowing back into the dishwasher. However, if they become obstructed, it can result in poor drainage. To address this issue, inspect the air gap or garbage disposal for any blockages or debris. Clear out any obstructions using a small brush or by flushing it with water. Once cleared, test the dishwasher to see if the drainage problem is resolved.

Clogged Filter or Drain Basket:

Frigidaire dishwashers are equipped with filters and drain baskets to prevent food particles from entering the drain pump and causing blockages. Over time, these filters and drain baskets can accumulate debris, hindering proper drainage. Begin by locating the filters and drain baskets, typically found at the bottom of the dishwasher. Remove them carefully and rinse them under running water to remove any trapped food particles. Ensure that they are completely clean before reinserting them into the dishwasher.

Malfunctioning Drain Pump:

If you have checked all the above components and the dishwasher still fails to drain, it’s possible that the drain pump itself is faulty. A malfunctioning drain pump may not be able to effectively expel the wastewater from the dishwasher. In such cases, it’s advisable to contact a professional appliance repair technician to inspect and replace the drain pump, if necessary.


Dealing with a Frigidaire dishwasher that isn’t draining properly can be a frustrating experience. However, armed with the knowledge of common causes and troubleshooting steps outlined in this guide, you are now well-equipped to tackle the issue head-on. Remember to start with the simplest solutions, such as clearing clogs or debris, before moving on to more complex repairs. In case you’re unsure or uncomfortable with troubleshooting your dishwasher, it’s always best to consult a qualified technician who can provide expert assistance.
