Check for Clogs in the Drainage System

One of the primary reasons for a Samsung dishwasher not draining is clogs in the drainage system. Here’s how to address it:

Step 1 – Inspect the Filter

Start by removing the bottom rack and inspecting the filter. Remove any debris or food particles that may be blocking the drainage. Ensure that you follow these steps meticulously:

  • Open the dishwasher door and pull out the bottom rack.
  • Locate the filter assembly at the bottom of the dishwasher.
  • Carefully remove the filter cover or mesh screen.
  • Check for any debris, food particles, or foreign objects.
  • Use a soft brush or cloth to clean the filter thoroughly.

Step 2 – Examine the Drain Hose

Check the drain hose for kinks, bends, or clogs. If you find any, straighten the hose and clear any obstructions. Follow these steps for a comprehensive inspection:

  1. Disconnect the dishwasher from the power source.
  2. Access the back of the dishwasher to locate the drain hose.
  3. Inspect the entire length of the hose for kinks or damage.
  4. If you find any kinks, gently straighten the hose.
  5. Use a plumber’s snake or a long, flexible brush to remove any clogs.

Step 3 – Clean the Air Gap

Inspect the air gap, which is usually located near the sink. Clean it thoroughly to ensure proper drainage. Here’s how to clean the air gap effectively:

  • Locate the air gap, typically installed on the countertop near the sink.
  • Remove the top cover of the air gap.
  • Rinse the cover and interior with warm, soapy water.
  • Use a small brush or pipe cleaner to clean any debris from the air gap.

Ensure Proper Installation

Improper installation can also lead to drainage issues. Here’s what you should verify:

Check the Dishwasher’s Position

Ensure that your dishwasher is level and securely installed under the countertop. An uneven dishwasher can affect drainage. Follow these installation steps:

  • Use a bubble level to ensure the dishwasher is level from side to side and front to back.
  • Adjust the dishwasher’s leveling feet as needed to achieve a level position.
  • Securely attach the dishwasher to the countertop to prevent movement.

Verify the Drain Hose

Make sure the drain hose is correctly connected to the sink’s drainage system or disposal unit. Follow these steps to verify the drain hose connection:

  1. Trace the drain hose from the dishwasher to its point of connection.
  2. Ensure that the hose is securely connected to the sink’s drain or disposal unit.
  3. Tighten any hose clamps or connectors to prevent leaks.

Examine the Drain Pump

The drain pump is crucial for removing water from the dishwasher. If it’s not functioning correctly, you’ll encounter drainage problems.

Inspect the Drain Pump Impeller

Check the impeller for any damage or debris that might be obstructing its movement. Replace it if necessary. Here’s how to inspect the drain pump impeller:

  • Access the drain pump, usually located at the base of the dishwasher.
  • Remove any debris or foreign objects that may be blocking the impeller.
  • Carefully inspect the impeller for signs of damage, such as cracks or missing blades.

Test the Drain Pump Motor

Run a diagnostic test on the drain pump motor to ensure it’s working as it should. Replace it if it’s faulty. To test the drain pump motor:

  1. Consult your dishwasher’s manual for instructions on running a diagnostic test.
  2. Follow the prescribed steps to initiate the test.
  3. Listen for the sound of the drain pump motor running.
  4. If the motor is silent or makes unusual noises, it may need replacement.

Final Steps to Resolve the Issue

Run a Cleaning Cycle

Running a cleaning cycle with a dishwasher cleaner can help remove any lingering debris and odors. Here’s how to run a cleaning cycle:

  • Purchase a dishwasher cleaner from a reputable brand.
  • Empty the dishwasher of dishes and utensils.
  • Follow the manufacturer’s instructions on using the cleaner.
  • Typically, you’ll place the cleaner in the detergent compartment or in a specific dishwasher-safe container.
  • Run the dishwasher on a hot water cycle to ensure thorough cleaning.

Regular Maintenance

To prevent future drainage issues, adopt a routine maintenance schedule. Clean the filter and drain regularly and ensure there are no blockages in the hose or air gap. Regular maintenance steps include:

  • Cleaning the filter every month.
  • Inspecting the drain hose and air gap for obstructions.
  • Running a cleaning cycle every few months, depending on usage.


A Samsung dishwasher not draining can disrupt your daily routine, but with the right troubleshooting steps, you can resolve the issue and enjoy clean, hassle-free dishes once again. Remember to maintain your dishwasher regularly to avoid future problems.
