Having a dishwasher at home is a luxury that helps make the tedious task of dishwashing more manageable. But what happens when your Samsung dishwasher does not evacuate the hot water? This drain issue can be frustrating and prevent the dishwasher from working correctly.
Not only does it leave your dishes wet, but it also affects the cleaning quality.
In this blog, we will guide you through the possible causes of why your Samsung dishwasher may not be draining and provide ten easy solutions to fix the issue. So, let’s dive into the details.
Why is your Samsung Dishwasher Not Draining?
Several factors can cause your Samsung dishwasher not to evacuate water properly. Let’s explore each possible cause in detail:
1. Clogged or Blocked Drain Hose
The hose is responsible for draining the water out of the dishwasher. Over time, food particles, grease, or debris can get clogged or blocked, preventing water from flowing out.
A blocked hose can also cause the water to back up, leading to leaks or water damage.
2. Defective Drain Pump
The responsibility of pumping water out of the dishwasher lies with the drain pump outlet. It can’t drain water if it’s not working correctly, leaving it stagnant in the dishwasher. A clogged drain impeller, a broken or faulty motor, or a malfunctioning drain solenoid can cause this.
3. Malfunctioning Drain Solenoid
A drain solenoid is a dishwasher device that controls the valve’s opening and closing. It’s an electromagnetic device that uses an electrical current to move a plunger or piston to open or close the valve.
When the dishwasher’s cycle is complete, the solenoid receives a signal from the control board to open the valve and allow the water to flow. The solenoid then energizes, creating a magnetic field that pulls the plunger or piston inside, opening the valve and allowing the water to pump out of the dishwasher.
4. Damaged Impeller
The impeller is a small, rotating dishwasher component responsible for pumping water out of the dishwasher during the drain cycle. It’s typically located inside the pump and uses centrifugal force to push the water out of the dishwasher and through the hose.
The impeller has several blades or fins that spin rapidly when the drain pump is activated. As the drain impeller spins, it creates a low-pressure area, which causes the water to be drawn into the pump.
The water then flows through the impeller’s blades, which spin it rapidly, pushing it out of the pump and through the drain hose.
5. Faulty Check Valve
The check valve prevents dirty water from flowing back into the dishwasher. If it’s faulty, it can’t stop the water from flowing back in, causing the dishwasher not to evacuate properly.
6. Overfilled Dishwasher
Sometimes, overloading the dishwasher can cause the water not to pump out properly. Overfilling the dishwasher can prevent the water from circulating correctly, causing it to remain stagnant in the dishwasher.
7. Blocked Garbage Disposal
If you have garbage disposal connected to your dishwasher, it can become clogged by food waste, preventing the water from draining properly. Food particles, grease, and debris can accumulate in the garbage disposal, causing it to clog.
8. Defective Drain Motor
If the drain motor is defective, it won’t be able to pump water out of the dishwasher, even if the hose is clean. The engine might have a broken impeller or a burned-out motor, which can prevent it from functioning correctly.
9. Clogged Air Gap
The air gap is a small device on the countertop or sink that prevents dirty water from flowing back into the dishwasher. If it’s clogged with debris or dirt, it can prevent water from pumping out of the dishwasher.
10. The Dishwasher’s drain filter
Food particles, trash, and other tiny things can become trapped in the dishwasher drain filter as it cycles through its numerous wash and rinse cycles.
Over time, this buildup can reduce the dishwasher’s ability to drain properly and cause water to remain in the dishwasher after the cycle.
How to Fix Samsung Dishwasher Not Draining?
Now that you know the possible causes, let’s explore the solutions to fix the issue. Here are ten easy ways to fix your Samsung dishwasher not draining:
1. Clean the Drain Hose
Cleaning the hose is one of the most common solutions to fixing a Samsung dishwasher, not evacuating. Here are some more detailed steps on how to clean the hose:
- Turn Off the Dishwasher:
Before cleaning the hose, turn off the dishwasher and disconnect the appliance from the electrical outlet. This will ensure that no electrical current is running through the dishwasher and that you can work safely.

The hose is usually located at the back of the dishwasher and can be identified as a flexible plastic or rubber tube. Check the user manual to find the exact location of the dishwasher drain hose in your specific dishwasher model.
- Remove The Drain Hose:
Carefully remove the hose from the dishwasher’s back by loosening the clamps or screws holding it. Be careful not to damage the hose while removing it.
- Clean The Drain Hose:
Once you have removed the hose, use a long brush to clean the inside thoroughly. Start from one end and work your way to the other, ensuring that all blockages, debris, or dirt are removed. You can also run water through the hose to pump out any remaining particles.
- Reattach The Drain Hose:
After cleaning the hose, reattach it to the dishwasher’s back and secure it with the clamps or screws you removed earlier. Ensure that it’s tightly secured to prevent leaks.
- Test The Dishwasher:
Once you’ve cleaned and reattached the drain hose, plug in the dishwasher and turn it on. Run a cycle to test if the dishwasher is draining correctly. If the dishwasher is still not flushing the water out, another issue might need to be addressed.
2. Check the Drain Pump
