A properly functioning drainage system is essential for a dishwasher to clean and dry your dishes effectively. If your Frigidaire dishwasher is not draining, it can lead to standing water at the bottom of the tub, foul odors, and unclean dishes. Addressing this problem promptly will ensure your dishwasher continues to work efficiently and prevent potential damage.

Common Causes of a Frigidaire Dishwasher Not Draining

  1. Clogged Drain Hose: A clogged drain hose is one of the primary causes of drainage issues in a dishwasher. Food particles, debris, or mineral buildup can obstruct the hose, preventing proper water flow.
  2. Blocked Air Gap: The air gap is a small device located on the countertop or sink near the dishwasher. Its purpose is to prevent backflow and ensure proper drainage. If the air gap is clogged, it can hinder the dishwasher’s ability to drain water effectively.
  3. Faulty Drain Pump: The drain pump is responsible for removing the water from the dishwasher. If it becomes faulty or damaged, it may not be able to pump the water out properly, resulting in poor drainage.
  4. Improperly Installed Garbage Disposal: In some cases, the dishwasher drain hose is connected to the garbage disposal unit. If the garbage disposal is not installed correctly or has a clog, it can cause drainage problems in the dishwasher.

Troubleshooting Steps to Fix a Frigidaire Dishwasher Not Draining

  1. Inspect the Drain Hose: Start by checking the drain hose for any clogs or kinks. Disconnect the hose from the dishwasher and sink to ensure there are no blockages. Clean the hose with warm water and a brush, removing any debris or food particles. Reconnect the hose securely.
  2. Clear the Air Gap: Remove the air gap cover and clean out any obstructions using a small brush or toothpick. Rinse it with water and ensure it is reinstalled properly.
  3. Test the Drain Pump: Locate the drain pump in your dishwasher. If it appears damaged or worn out, it may need to be replaced. Check the pump impeller for any obstructions and remove them if necessary.
  4. Verify the Garbage Disposal Connection: If your dishwasher is connected to a garbage disposal, make sure the connection is secure and free of clogs. Run water through the disposal to ensure it is functioning correctly.
