If you’re facing the frustrating situation of your Samsung dishwasher not draining and producing a humming sound, you’re not alone. Many homeowners encounter this issue, which can turn a simple chore into a headache. In this comprehensive guide, we’ll explore the possible reasons behind the problem and provide you with actionable solutions to get your dishwasher back on track.
Understanding the Problem: The Basics of Dishwasher Drainage
Dishwashers are intricate machines designed to handle the messy job of cleaning dishes with ease. However, like any appliance, they can develop issues over time. When your Samsung dishwasher fails to drain, it can lead to pooling water at the bottom, which not only prevents proper cleaning but can also create unpleasant odors. A humming sound typically indicates that the dishwasher’s motor is working but struggling to perform its function effectively.
Common Reasons Your Samsung Dishwasher is Not Draining
To fix the issue, it’s crucial to understand what might be causing the malfunction. Here are some of the most common reasons your Samsung dishwasher may not drain and is making a humming noise:
1. Blocked Filter
One of the first areas to check when your dishwasher is not draining is the filter. Over time, food particles and debris can accumulate, causing clogs that prevent water from draining properly.
Signs of a Blocked Filter:
– Standing water in the bottom of the dishwasher.
– Visible debris on the filter itself.
How to Clean the Filter:
- Open the dishwasher door and remove the bottom rack.
- Locate and twist the filter to remove it.
- Rinse the filter under hot water to remove debris before reinserting it.
2. Clogged Drain Hose
The drain hose is responsible for transporting used water from your dishwasher to the kitchen’s drainage system. If this hose becomes kinked or clogged, drainage will be hindered, leading to humming sounds as the motor runs.
Symptoms of a Clogged Drain Hose:
– Water pooling at the bottom of the dishwasher.
– Humming sound comes and goes, often consistent with the drain cycle.
Steps to Check the Hose:
- Inspect the drain hose for any visible kinks or bends.
- Disconnect the hose and flush it with warm water to remove any blockages.
3. Malfunctioning Drain Pump
The drain pump is crucial for pushing water out of the dishwasher. If the drain pump is defective, you may hear a humming sound without the unit draining any water.
Indicators of a Faulty Drain Pump:
– Humming noise persists even with an empty dishwasher.
– Water remains pooled in the bottom even after multiple cycles.
What to Do if the Drain Pump is Defective:
- Check for any visible obstructions within the pump.
- If the pump shows signs of damage or wear, it may need to be replaced. Consult your Samsung dishwasher manual for detailed replacement instructions.
4. Faulty Water Inlet Valve
The water inlet valve controls the flow of water into the dishwasher. If it’s stuck in the open position, it may cause water to continuously flow, leading to drainage problems. When malfunctioning, it may also trigger a humming noise due to the constant requests from the motor.
Symptoms of a Faulty Water Inlet Valve:
– Water pooling in the bottom of the dishwasher during a cycle.
– Humming sound without the unit filling with additional water.
Checking the Water Inlet Valve:
- Turn off the water supply and disconnect the dishwasher from power.
- Remove the cover and check the valve for any signs of blockage or damage.
Steps to Diagnose and Fix Your Samsung Dishwasher
Now that we’ve outlined the potential causes of your dishwasher’s issues, let’s walk through some detailed steps to diagnose and potentially fix them.
Step 1: Perform an Initial Inspection
Before jumping into repairs, start with a thorough inspection:
– Check for Blockages: Begin with visible signs of debris or food particles in the filter and drain area.
– Listen to the Sounds: Notice if the humming is consistent or if it changes when you manipulate the door or controls.
Step 2: Clean the Dishwasher Thoroughly
Sometimes, a thorough clean can resolve several issues:
– Clean the interior surfaces and check for anything lodged in the spray arms.
– Use a dishwasher cleaner specifically designed to eliminate residues.
Step 3: Test the Drain Function
After performing your inspection and cleaning, conduct a quick test:
1. Run a short cycle without dishes.
2. Observe if the water drains efficiently and if any noises change.
Step 4: Inspect Electrical and Mechanical Components
If the dishwasher is still not draining:
– Use a multimeter to check the continuity of the drain pump and water inlet valve.
– Consult a professional if you’re uncomfortable working with mechanical and electrical components.

What could cause my Samsung dishwasher to hum but not drain?
The humming noise from your Samsung dishwasher often indicates that the motor is trying to operate but is facing a blockage. Common culprits include food particles or debris obstructing the drain impeller or filter. It’s essential to check these components regularly; if they are clogged, water can’t flow through appropriately, which results in the humming sound as the motor struggles to drain.
To resolve this issue, begin by unplugging the dishwasher and removing the bottom rack. Take out the filter and inspect it for any buildup, then clean it under running water. Also, examine the drain area for any obstructions. Once everything is clear, reassemble your dishwasher and try running a cycle again to see if the issue persists.
How can I tell if the drain pump is malfunctioning?
A malfunctioning drain pump is often behind the draining issues in your Samsung dishwasher. If you notice continuous humming, this might suggest the pump is trying to work but cannot due to an internal fault. You can perform a quick check by listening closely to your dishwasher during a cycle; if you hear an irregular sound or a prolonged hum, it may point to a pump failure.
To confirm whether the drain pump is faulty, you can access it by removing the lower spray arm and filter. Check for any visible signs of damage or obstructions. If everything looks clean but the dishwasher still won’t drain, the pump may need to be tested with a multimeter to ensure it’s receiving power and functioning correctly. If it’s defective, replacement may be necessary.
Is there a chance the dishwasher is overloading?
While it might seem unusual, overloading your Samsung dishwasher can lead to draining issues. When dishes are packed too tightly, water may not circulate efficiently, preventing proper draining at the end of a cycle. This can create a scenario where dishes remain wet and residual water accumulates inside the unit, which can be accompanied by a humming noise as the drain tries to work.
To rectify this, ensure that you’re loading your dishwasher according to the manufacturer’s guidelines. Make sure to leave sufficient space between dishes for water to flow freely, and avoid stacking items in a way that blocks the spray arms. Running a lighter load can also help you determine if overloading is the underlying issue.
What maintenance should I perform to prevent draining issues?
Regular maintenance is crucial to prevent draining issues in your Samsung dishwasher. Start by routinely cleaning the filter and removing any food debris that may have collected inside. Additionally, it’s a good practice to check the drain hose for kinks or clogs that could hinder water from exiting the machine effectively. Keeping these areas clean will help ensure optimal performance.
You should also periodically run maintenance cycles with cleaning agents designed for dishwashers. This can help remove limescale or grease buildup in the plumbing and components of your dishwasher. Doing so not only enhances the cleaning efficiency but minimizes the chances of hums and drainage problems down the line.
Could a clogged drain hose be the problem?
Yes, a clogged drain hose is a common issue that can cause your Samsung dishwasher to hum instead of draining. The drain hose allows water to exit the unit; if it becomes obstructed due to food debris, soap buildup, or even kinks, it can prevent water from flowing out. As a result, the pump may continue to run, creating a humming noise as it attempts to expel the water.
To check for clogs, inspect the drain hose connected to the sink or garbage disposal for any visible blockages. Detach the hose and run water through it to see if it flows freely. If not, you may need to clean or replace the hose entirely. Once cleared, reattach the hose and run a cycle to see if the draining issue persists.
Should I call a professional if the problem continues?
If you’ve tried troubleshooting and still face issues with your Samsung dishwasher humming and not draining, it may be time to call a professional. Continuous problems could indicate that the issue lies beyond basic clogs or maintenance, such as internal component failures or electrical issues. A professional technician can offer a thorough diagnostic assessment and determine the solution needed to resolve the problem.
Furthermore, attempting complex repairs on your own without proper expertise might lead to more damage or safety hazards. A qualified technician can address issues with the motor, pump, or electronic controls, ensuring the repair is done correctly and restoring your dishwasher’s performance safely.
