Drainage Problems in Your Samsung Dishwasher

Samsung Dishwasher Not Draining

A Samsung dishwasher is a valuable appliance that streamlines your kitchen routine, but when it fails to drain properly, it can be frustrating. If you're facing the problem of a Samsung dishwasher not draining, don't worry! In this troubleshooting guide, we'll explore the possible causes and provide effective solutions to help you resolve the issue and restore your dishwasher's functionality.

Checking the Drain Hose

One of the common culprits behind a dishwasher not draining is a clogged or improperly installed drain hose. Here's how you can address this issue:

  1. Inspect the Drain Hose: Carefully examine the drain hose for any kinks, twists, or blockages. Straighten out any bends and remove any debris or obstructions that may be obstructing the flow of water.
  2. Verify Proper Connection: Ensure that the drain hose is securely connected to both the dishwasher and the sink drain. Check for any loose fittings or leaks that may be impeding the drainage process. Tighten the connections if necessary.

Clearing the Air Gap

If your dishwasher has an air gap, it can also cause drainage problems. Follow these steps to address the issue:

  1. Remove the Cover: Locate the air gap, usually installed on the countertop or sink, and remove the cover.
  2. Clean the Air Gap: Inspect the air gap for any debris or buildup that may be obstructing the flow of water. Clean out any residue using a brush or toothpick. Rinse the air gap thoroughly to ensure it is free from blockages.
  3. Reassemble the Air Gap: After cleaning, reassemble the air gap, making sure it is properly aligned and securely attached. Check if the dishwasher drains correctly after reinstallation.

Cleaning the Filter

A dirty or clogged filter can hinder proper drainage in your Samsung dishwasher. Follow these steps to clean the filter:

  1. Locate the Filter: The filter is typically found at the bottom of the dishwasher. Consult your dishwasher's manual to find the exact location.
  2. Remove and Rinse the Filter: Carefully remove the filter and rinse it under running water to remove any accumulated food particles or debris. Make sure to remove all residue and ensure the filter is clean.
  3. Reinstall the Filter: After cleaning, securely reinstall the filter in its original position. Ensure it fits snugly and correctly. A properly cleaned filter will improve drainage performance.

Inspecting the Drain Pump

A malfunctioning drain pump can prevent your dishwasher from draining effectively. Here's what you can do:

  1. Refer to the Manual: Consult your dishwasher's manual to locate the drain pump. Familiarize yourself with its appearance and location.
  2. Check for Damage or Blockage: Inspect the drain pump for any signs of damage, such as cracks or leaks. Additionally, check for blockages that may be impeding the pump's operation. Clean the pump and ensure it spins freely.
  3. Professional Assistance: If the drain pump appears faulty or damaged, it may need to be replaced. Contact a professional Samsung appliance technician for further assistance.

Verifying the Garbage Disposal

If your Samsung dishwasher shares a drainage line with a garbage disposal unit, ensure the disposal is functioning correctly:

  1. Run the Garbage Disposal: Switch on the garbage disposal and confirm that it is operating normally. If it is clogged or not functioning, it can obstruct the dishwasher's drainage. Refer to the disposal's manual for troubleshooting or seek professional help if needed.

Examining the Check Valve

A malfunctioning check valve can lead to drainage problems. Here's how to address it:

  1. Locate the Check Valve: Identify the check valve's position, usually located at the drain pump or drain hose connection.
  2. Check for Free Movement: Ensure that the check valve moves freely without any obstructions. Clean or replace the check valve if it's damaged or stuck.


By following these troubleshooting steps and checking the drain hose, clearing the air gap, cleaning the filter, inspecting the drain pump, verifying the garbage disposal, and examining the check valve, you can effectively address the issue of a Samsung dishwasher not draining. If the problem persists despite your efforts, it's recommended to contact a professional Samsung appliance technician for further assistance.
