Samsung Dishwasher SC Code: Causes & 7 Ways To Fix It Now

Dishwashers have become an indispensable part of modern households, streamlining the tedious task of washing dishes. Samsung dishwashers, known for their efficiency and reliability, are no exception. However, the panel sometimes shows issues like any other appliance, including a water level error.

The SC code is one of the display panel’s most common dishwasher error codes. In this blog, we’ll explore the causes of the Samsung dishwasher SC code, provide seven potential solutions to fix the issue and discuss preventative measures to ensure your dishwasher runs smoothly in the future.

Samsung Dishwasher SC Code
The Samsung dishwasher SC code indicates an issue with the dishwasher’s draining system, which might result from a clogged drain hose, a faulty drain pump, or a blocked filter. Regular maintenance and proper usage can help prevent this error from occurring.

Causes of Samsung Dishwasher SC Code

The Samsung dishwasher SC code error can be caused by various issues related to the draining system, including a clogged drain hose, a faulty drain pump, or a blocked filter, all of which impede the appliance’s ability to remove water during its wash cycle efficiently.

1. Clogged Drain Hose

A clogged drain hose is a common cause of the SC error code on Samsung dishwashers. Over time, as food waste – particles, grease, and other debris accumulate within the hose, the water flow becomes obstructed, causing the dishwasher to display this error code.

The restricted water flow prevents the dishwasher from effectively draining, which may lead to poor cleaning performance and damage the appliance. Regularly checking and cleaning the drain hose can help avoid this issue, ensuring the smooth operation of your Samsung dishwasher and maintaining its overall efficiency.

2. Faulty Drain Pump

Another cause of the SC error code is a malfunctioning drain pump. The drain pump plays a crucial role in the dishwasher’s operation, removing water from the unit. When the pump fails to function correctly, water remains inside the dishwasher, causing the SC code to appear.

This issue affects the appliance’s performance and poses a risk of damage due to water leakage or electrical shorts. It is essential to promptly address a faulty drain pump by repairing or replacing the component to ensure your Samsung dishwasher’s longevity and optimal performance.

3. Blocked Filter

A blocked filter is another cause of the SC error code in  Samsung dishwashers. The filter’s primary function is to trap food waste and other debris, preventing them from entering the drain pump and causing damage.

Over time, if not cleaned regularly, the filter can become clogged, restricting water flow and leading to the appearance of the SC code.

A clogged filter can also compromise the dishwasher’s cleaning performance and cause unpleasant odors. To avoid this issue, inspect and clean the filter routinely; this ensures the proper functioning of your Samsung dishwasher and maintains its overall effectiveness.

How to Fix Samsung Dishwasher SC Code?

To address the Samsung dishwasher SC code, simple steps can be implemented, such as cleaning the drain hose, replacing the drain pump, or cleaning the filter, all of which aim to restore the appliance’s optimal performance by resolving issues related to its draining system.

1. Clean the Drain Hose

Cleaning the drain hose is an effective solution for fixing a clogged drain hose that causes the SC drain error code to appear on your Samsung dishwasher. To do this, start by disconnecting the hose from the dishwasher and carefully inspecting it for any visible obstructions or soap.

Use a long brush or a straightened coat hanger to remove any debris within the hose. You can also run water through the hose to flush out any remaining particles for a more thorough cleaning. Once the hose is free of blockages, reconnect it to the dishwasher, ensuring a proper and secure sink connection.

This simple yet essential maintenance task can significantly improve your dishwasher’s draining performance and prevent the recurrence of the SC code.

2. Replace the Drain Pump

In cases where the drain pump is faulty, replacement may be necessary to resolve the SC error code issue in your Samsung dishwasher. To replace the drain pump, consult your dishwasher’s user manual for specific instructions and safety precautions about drain connection.

If you’re uncomfortable with replacing it, consider contacting a professional technician to handle the task. A trained technician can accurately diagnose the issue, obtain the appropriate replacement part, and install the new drain pump safely and efficiently.

3. Clean the Filter

Cleaning the filter is another practical solution for fixing the SC error code on the control board caused by a blocked drain filter in your Samsung dishwasher. To clean the filter, first, remove it from the dishwasher according to the manufacturer’s instructions.

Next, clean the drain pump filter thoroughly by rinsing it under running water for a few minutes to remove any loose debris. For stubborn particles, use a soft brush to scrub the filter gently, not using too much power to damage it. Once the drain pump filter is clean, reinstall it in the dishwasher, ensuring it is securely in place.

4. Check for a Kinked Drain Hose

A kinked or bent drain hose can lead to the SC code appearing on your Samsung dishwasher, which hinders the proper water flow during draining. Locate the drain hose to address this issue, typically connected to the dishwasher’s rear or under the sink.

Carefully inspect the hose for any kinks, bends, or pinched sections obstructing the water flow. If you find any, gently straighten the hose, not damaging it. Restoring the proper shape of the drain hose can improve drainage, resolve the SC drain error code issue, and enhance the overall performance of your dishwasher.

5. Reset the Dishwasher

Resetting the dishwasher can resolve the SC code issue, allowing the appliance to reset its internal systems and clear any temporary glitches. To perform a reset, first, turn off your Samsung dishwasher and unplug it from the power source.

Wait for approximately 10 minutes to ensure the appliance is fully powered down. Afterward, plug the dishwasher back into the power source and turn it on. This process allows the dishwasher to reset its internal components, potentially resolving the SC code and any other minor issues that may have arisen.

6. Inspect the Drain Check Valve

The drain check valve plays a crucial role in your Samsung dishwasher’s draining system, preventing water from flowing back into the dishwasher once drained. A stuck or malfunctioning drain check valve can cause the SC dishwasher error code to appear, indicating a problem with the draining process.

To address this issue, locate the drain check valve in your dishwasher, typically at the bottom of the unit near the drain pump. Inspect the valve for any visible damage or obstructions, and ensure it functions correctly. If the valve shows signs of damage or is stuck, replace it with a new one.

7. Clean the Air Gap

If your dishwasher has an air gap installed, it may cause the SC code. The air gap prevents water from siphoning back into the dishwasher and can become clogged with debris over time. Remove its cover to clean the air gap and clear out any debris or buildup.

Once cleaned, reassemble the air gap and check if the SC code has been resolved.

Preventing Samsung Dishwasher SC Code

To prevent the Samsung dishwasher SC error code from occurring, adopting proactive measures such as regular maintenance, proper dish loading, and using the correct detergent can help maintain the machine’s optimal performance and prevent issues related to any potential leak.

1. Regular Maintenance

Regular maintenance prevents the Samsung dishwasher SC error code and ensures optimal performance. By periodically cleaning essential components such as the filter, drain hose, and spray arms, you can prevent debris buildup that may lead to clogs or other issues in the draining system.

Additionally, routine maintenance helps extend the lifespan of your dishwasher and reduces the risk of more severe problems developing in the future.

2. Scrape Dishes Before Loading

Scraping dishes of excess food before loading them into the dishwasher is another effective preventative measure against the SC code. By removing larger food particles, you can significantly reduce the likelihood of clogs forming in the dishwasher drain hose or filter.

This simple yet essential step can significantly improve the dishwasher’s overall performance and prevent issues such as poor cleaning results, unpleasant odors, or the dreaded SC code (that you don’t want to see on the control panel).

Taking a few moments to scrape your dishes before loading them into the dishwasher can help maintain the appliance’s efficiency and prolong its service life. Take the pressure off your dishwasher by performing this simple task.

3. Use the Correct Detergent

Using the correct dishwasher detergent is essential in preventing clogs and maintaining the smooth operation of your Samsung dishwasher. The suitable detergent can help break down food particles, grease, and other debris more effectively, reducing the risk of blockages in the draining system.

To determine the best detergent for your dishwasher, consult your appliance’s user manual for recommended products. By selecting the correct detergent, you not only prevent the SC code from appearing but also ensure that your dishes are consistently cleaned to a high standard.
