Samsung washer SC code: causes and how to clear a drain error
By Daniel Brooks, Home maintenance writer and appliance troubleshooting specialist based in Charlotte, NC. Reviewed [date — human adds].
Quick answer
The SC code on a Samsung washer means the machine isn't draining water fast enough within the time it expects, usually because of a clogged pump filter, a kinked drain hose, or the hose being positioned too high. Here's how to check each, in order, and how to deal with standing water safely.
⚠
Safety first: dealing with standing water
Unplug the washer before accessing the drain pump filter, usually behind a small access panel at the bottom front of the machine. Have towels and a shallow pan ready, since the filter housing holds residual water that will come out as soon as you open it.

What to check
SC
Drain error, the washer isn't draining within its expected time window
Clogged drain pump filter, kinked or clogged drain hose, small object stuck in the pump, drain hose positioned above the recommended height
Drain pump filter, drain hose for kinks and blockages, drain hose height
Samsung's own support documentation ties this code to water remaining in the drum after the drain phase should have finished, which almost always traces back to something physically blocking the drain path rather than a bigger mechanical failure (Samsung washer error code support).
Work through it in order
1
Clean the drain pump filter
Open the filter access panel, typically at the bottom front of the machine, and place a shallow pan underneath before you remove the cap. Clean out lint, coins, or any other debris caught in the filter itself.
2
Check the drain hose for kinks
Follow the hose from the back of the washer to the drain point, whether that's a standpipe or a sink drain, and look for tight bends or visible clogs along the way.
3
Confirm the drain hose height
Most washers require the drain hose to sit within a specific height range for the pump to drain properly. The exact figure varies by model, so check your washer's install manual rather than assuming a universal number. A hose routed too high can trigger SC even with no actual clog anywhere in the system.
4
Rule out a failed drain pump
If the filter is clean and the hose checks out on both length and height, the drain pump motor itself may have failed. This points to a technician rather than further DIY troubleshooting.
What to do about the water still in the tub
Most Samsung washers allow a manual drain through the same filter access panel, even if the SC fault happens mid-cycle. Place a shallow pan underneath, open the cap slowly, and let the water drain out gradually rather than all at once, so clothes and water aren't stuck in the tub indefinitely while you work through the steps above.
When to call a technician
Call a technician if SC persists after a clean filter and a clear, correctly routed hose, if the pump makes an unusual grinding sound or no sound at all when the cycle tries to drain, or if water won't drain manually through the filter access either.

FAQ
What does SC mean on a Samsung washer?
SC signals a drain error. The washer detects that water isn't leaving the tub within the expected time during the drain phase and stops the cycle rather than continuing with standing water. It almost always traces to a blocked filter, hose, or pump.
How do I manually drain my Samsung washer if it's stuck with SC?
Most Samsung washers have a small drain pump filter access panel at the bottom front of the machine. Unplug the washer, place a shallow pan underneath, and slowly open the filter cap to let residual water drain before removing the filter fully to check for clogs.
Can a coin or small object cause an SC error?
Yes, this is one of the most common causes. Coins, buttons, hair ties, and similar small items can work their way into the drain pump filter or the pump itself and physically block drainage, which the washer reads as an error even though nothing is mechanically broken.
Does the height of the drain hose matter for the SC code?
Yes. Most Samsung washers require the drain hose to be routed within a specific height range. Too high, and the pump can't push water high enough to drain properly, which can trigger SC even with no actual clog. Check your model's install manual for the exact requirement.
