A malfunctioning dishwasher can quickly become a homeowner’s worst nightmare, especially when the dishes come out dirty and the water fails to drain. If you’re experiencing the frustrating issue of a Samsung dishwasher not draining, fear not! In this comprehensive troubleshooting guide, we will walk you through the potential causes and offer practical solutions to get your dishwasher back up and running efficiently.

Understanding the Problem

When faced with a Samsung dishwasher not draining, it’s crucial to first assess the situation and understand the potential causes. Several factors can contribute to this issue, including a clogged drain hose, a faulty drain pump, or an obstructed air gap. By identifying the underlying problem, you can take appropriate steps towards resolving it.

Checking the Drain Hose

The drain hose plays a vital role in ensuring proper drainage in your Samsung dishwasher. If the dishwasher is not draining, one possible culprit could be a clogged or kinked drain hose. Begin by disconnecting the hose from both the dishwasher and the sink drain, ensuring you have a bucket or towel to catch any excess water. Carefully inspect the hose for any obstructions or bends that may hinder water flow. If you find any, gently remove the blockage or straighten the hose before reconnecting it.

 Examining the Drain Pump

Another component that can cause a Samsung dishwasher not to drain is a faulty drain pump. The drain pump is responsible for removing the water from the dishwasher during the drain cycle. To assess if the drain pump is functioning correctly, locate it beneath the dishwasher and inspect it for any debris or damage. Clear away any obstructions and ensure the impeller, the small rotating component within the pump, is free from any blockages. If the drain pump appears damaged or fails to operate despite your efforts, it may require replacement.

Clearing the Air Gap

An obstructed air gap can also lead to drainage issues in your Samsung dishwasher. The air gap is a small device typically located on the sink countertop or the back of the dishwasher. It prevents dirty water from flowing back into the dishwasher and instead directs it to the sink drain. To check if the air gap is the problem, remove its cover and clean out any debris or residue that may be causing an obstruction. Reassemble the air gap and run a test cycle to see if the dishwasher now drains properly.

Verifying the Garbage Disposal Connection

If your Samsung dishwasher is connected to a garbage disposal unit, it’s essential to ensure the connection is properly installed. A loose or incorrect connection can obstruct the water drainage, leading to the dishwasher not draining. Confirm that the drain hose is securely attached to the disposal unit and that there are no blockages within the disposal itself. Additionally, make sure the knockout plug, a small plastic piece located inside the disposal’s dishwasher inlet, has been removed. This plug needs to be removed for proper drainage.

Seeking Professional Assistance

If you have exhausted all the troubleshooting steps mentioned above and your Samsung dishwasher still refuses to drain, it may be time to seek professional help. Contact Samsung’s customer support or schedule a service visit from a qualified technician. They have the expertise and tools to diagnose and address complex issues that might require professional intervention.


A Samsung dishwasher not draining can be an inconvenience, but with proper troubleshooting, you can restore its functionality and enjoy sparkling clean dishes once again. By checking the drain hose, examining the drain pump, clearing the air gap, verifying the garbage disposal connection, and reaching out for professional assistance if needed, you can resolve this issue and keep your dishwasher running smoothly. Remember to maintain regular maintenance routines and promptly address any future problems to ensure optimal
