How to Fix SC Error Code on Samsung Washer?

A Samsung washer is a reliable appliance, but sometimes, error codes like SC (or 5C) can appear, causing drainage issues. The SC error code on a Samsung washer indicates that the machine is taking too long to drain water due to a blocked drain hose, clogged pump filter, faulty drain pump, or pressure switch malfunction. If left unresolved, this issue can lead to standing water, mold buildup, and potential washer damage.

In this guide, we’ll explain what SC means on a Samsung washer, explore the common causes, and provide step-by-step solutions to fix the error. We will also discuss when to call a technician and how to prevent drainage problems in the future. Follow this detailed troubleshooting guide to get your Samsung washer running smoothly again!

What Does SC Mean on a Samsung Washer?

The SC error code on a Samsung washer indicates a drainage issue. This means your washer is taking too long to drain water during a wash cycle. The SC code is similar to 5C, SE, 5E, nd, 1 5C, and other Samsung washer error codes related to drainage problems.

If left unresolved, the SC error can lead to more serious issues, such as water leakage, mold buildup, or complete washer malfunction. Fortunately, fixing it is relatively simple.

Common Causes of the SC Error Code on Samsung Washers

The SC code on a Samsung washer usually happens due to:

• Clogged drain hose (blockages or improper installation).
• Dirty or blocked pump filter (prevents water from draining).
• Faulty drain pump (obstructions, damage, or electrical failure).
• Malfunctioning pressure switch (incorrect water level detection).
• Temporary control board glitch (can be reset easily).

How to Fix SC Error Code on Samsung Washer?

Here are the step-by-step solutions to fix the Samsung washer SC code error.

1. Clean the Pump Filter (For Front-Loader Washers)

Samsung front-load washers have a pump filter (also called debris filter) that collects dirt, lint, and small objects. A clogged filter can cause drainage issues, leading to the SC error on a Samsung washing machine.

Steps to Clean the Pump Filter:

1. Turn off your washer and unplug it from the power source.
2. Open the pump filter access panel (usually located on the bottom front of the washer).
3. Locate the black rubber drain hose and pull it out.
4. Remove the drain plug and drain any trapped water into a container.
5. Unscrew and remove the pump filter (turn counterclockwise).
6. Clean the filter using warm water and a small brush to remove lint and debris.
7. Put the filter back in place and secure it tightly.
8. Reattach the drain hose and close the panel.

Pro Tip: Samsung recommends cleaning the pump filter once a month or after 40 laundry cycles to prevent drainage issues.

2. Check the Drain Hose for Blockages

A kinked, clogged, or improperly installed drain hose can prevent water from draining, triggering the SC error code on a Samsung washer.

Steps to Inspect and Fix the Drain Hose:

1. Turn off the washer and unplug it.
2. Locate the drain hose (behind the washer).
3. Check for kinks or twists in the hose. Straighten it if needed.
4. Disconnect the hose from the washer and drain system.
5. Use a drain snake or hot water with vinegar to clean out any blockages.
6. Reconnect the drain hose properly:
   • Ensure it is not inserted more than 6 inches into the standpipe.
   • The drain hose height should be between 18-96 inches from the ground.
7. Turn the washer back on and run a drain cycle to test if the SC error is cleared.

3. Inspect the Drain Pump

If the pump filter and drain hose are clear, but the SC error on a Samsung washer persists, the drain pump may be blocked or faulty.

Steps to Check the Drain Pump:

1. Unplug the washer and turn off the water supply.
2. Remove the rear access panel (for front-load washers) or tilt the washer forward (for top-load washers) to access the drain pump.
3. Disconnect the drain pump wiring harness and hoses.
4. Remove any lint, clothing, or debris stuck in the pump.
5. Check the pump impeller:
   • Try spinning the impeller manually.
   • If it doesn’t spin or is damaged, the pump must be replaced.
6. Use a multimeter to test for continuity in the drain pump motor.
7. If the pump fails the continuity test, replace the drain pump.

Pro Tip: If the washer makes a humming noise but doesn’t drain, the drain pump may be stuck or broken.

4. Check the Pressure Switch (Water Level Sensor)

A faulty pressure switch may send incorrect signals to the washer, causing improper drainage and triggering the SC error on a Samsung washing machine.

Steps to Test the Pressure Switch:

1. Unplug the washer and locate the pressure switch (usually near the control panel).
2. Remove the air hose connected to the pressure switch and check for blockages.
3. Use a multimeter to test for continuity in the pressure switch.
4. If it doesn’t show continuity, replace the pressure switch.

5. Reset the Washer to Fix a Control Board Glitch

Sometimes, the SC error code on a Samsung washer is caused by a temporary glitch in the control board. A simple reset may fix it.

Steps to Reset Your Samsung Washer:

1. Turn off the washer and unplug it from the power source.
2. Wait 2-5 minutes for the control board to reset.
3. Plug the washer back in and turn it on.
4. Run a drain cycle to check if the SC error is cleared.

Other Possible Causes of SC Error Code on Samsung Washers

If the drain filter, drain hose, drain pump, and pressure switch are all working properly, but the SC error code still appears, other possible issues include:

• Control Board Failure – The main control board might be malfunctioning and sending incorrect signals. A technician may need to repair or replace the control board.
• Faulty Door Lock/Lid Switch – If the door lock or lid switch is defective, it might prevent the washer from draining properly.
• Worn-Out Washer Timer – A malfunctioning timer can cause drainage issues and should be replaced if necessary.

Conclusion

The SC error on a Samsung washer indicates a drainage problem caused by a clogged pump filter, blocked drain hose, faulty drain pump, or pressure switch issues. Regular maintenance of these components can prevent drainage errors and keep your washer working efficiently.

If none of the troubleshooting steps resolve the issue, contact Samsung support or a qualified appliance repair technician for professional assistance.
