If your Samsung washer is displaying an SC error code, it means the appliance has a drainage problem because the drainage cycle is taking too long to complete. Most of the time, this error code can be resolved by unblocking the drain hose or drain pump filter, but in some cases, the drain pump or the pressure switch may be defective and will need to be repaired or replaced.
Before you get started with our step-by-step guide below, start by turning your washer off for a couple of minutes and then turn it back on and check if the error code is gone and your washer is working again. If a simple reset didn’t work, start with step one below and work your way down the guide until you find the faulty component in your washer and fix it.
This guide applies to all major Samsung washing machine models, including:
Step 1 – Clean the pump filter.
If you have a front-loading Samsung washer, the first step is to clean the pump filter. If you have a top-loading washer, proceed to step 2. The pump filter is located on the front of the washer and is there to catch any loose debris so they don’t end up in the pump. According to Samsung, you should clean the pump filter out every month to prevent it from overflowing and to prevent odors and mold from developing.
Here’s how to clean the pump filter in your Samsung washer:
- Locate the pump filter access panel (you can open it by pressing the cover).
- Once you’ve opened the panel, you should see a drain hose. The hose has a plug in it that you need to remove and then pour any excess water in the hose into a bucket, so it doesn’t leak onto the floor.
- Next, remove the filter. This can be done by either turning it counterclockwise and gently pulling it out or you may need to push it in and turn it slightly before being able to pull it out.
- Once removed, thoroughly clean the filter.
- Place the filter back into position and reattach the hose.
- Close the access panel and test if the error code is gone. If it’s still showing, proceed to step 2.
Step 2 – Check the drain hose.
If your Samsung washer isn’t able to drain and the SC code is showing, it may be the result of the drain hose being blocked or kinked out of shape so water cannot flow through it. To check the drain hose, you will need to disconnect it from your washer which will require you to pull the washer out from the wall.
Here’s how to check the drain hose:
- Switch the power off to your washing machine.
- Turn the water supply off to your washing machine.
- Pull your washer out from the wall (make sure you watch the hoses as they are sometimes not long enough for your appliance to come completely out from the wall).
- Locate the drain hose and disconnect it from the washer (you will probably have to loosen the clamps on it to be able to disconnect it).
- Once the drain hose is removed, pour water through it to check if it’s blocked. If the hose isn’t blocked, wash it out and reattach it to the dishwasher and move on to step 3.
- If blocked, use a piece of wire or a specialist drain snake tool to unblock it and then reattach it to the dishwasher. You can then test if the error code is gone. If not, proceed to step 3.
Step 3 – Test the drain pump.
If the pump filter and the drain pump are not the cause of the error code, the next step is to test the drain pump. The pump is responsible for draining the water out of your washing machine at the end of a cycle. If it becomes defective, your Samsung washer will not drain, and the SC error code will show.
Here’s how to test the drain pump:
- Switch the power to your washing machine off.
- Turn the water off.
- Locate the drain pump. If you have a front-loader washer, you’ll find it behind the rear access panel. If you have a top loader, you’ll find it underneath the washer, so you’ll have to turn it on its side to access it.
- Once located, remove the wire connector from the pump.
- Next, remove the drain hose from the pump (you may have to remove the clamps that hold it in place).
- Unthread the screws that hold the pump in place and then remove the pump completely from the washer.
- Once removed, check the pump for any signs of damage. If damaged, it will need to be replaced.
- Before replacing it, check the pump motor with a multimeter to see if it has continuity.
- If the pump fails the test, replace it. if it passes the test, reattach it to your washer and then proceed to the final step.
- Once the new pump is installed, check if the SC error code is gone from the display screen on your Samsung washer. If the error code is still showing, proceed to the final step.
Step 4 – Test the pressure switch.
The final step is to test the pressure switch. The purpose of the pressure switch is to tell the control board when it should activate the drain pump or the inlet valve to let more water into the washer. If it becomes defective, your washer might not drain, and the SC error code may appear.
Here’s how to test the pressure switch:
- Switch the power off to your washer.
- Turn the water supply off to your washer.
- Locate the pressure switch (it’s located at the top of the washer unit. You may need to check your user manual to find out its exact location in your specific Samsung washer).
- Once located, disconnect the switch, and then remove it from your washer.
- Test the switch with a multimeter to see if it has continuity.
- If it fails the test, replace the switch and check if the error code is gone. If it passes the test, reattach the switch to your washer.
- If the error code is still showing even after replacing the pressure switch and/or checking all the other components, you will need to get a qualified technician to inspect your washer to see if they can find the reason the error code is showing.
