Samsung Washer 5C Error Code — What It Means
On Samsung washers, the 5C or SC error code signals a drainage fault. The control system has detected that the tub is not draining within the expected time, so it stops normal operation and may refuse to fill or spin until the condition clears. The washer believes water is still in the tub too long, or it cannot verify that the tub has drained properly.
Samsung user documentation and service summaries consistently treat SC/5C as a drain error tied to the drain system or the pressure-sensing circuit that confirms an empty tub. It is not a wash-motor or door-lock code. The fault can stem from a physical blockage in the drain path or, less commonly, from a pressure-sensing issue that prevents the machine from recognizing that the tub is actually empty.
Before You Replace Anything
Homeowners often replace the drain pump motor or even the control board before checking for physical clogs. Clean the filter, inspect the drain hose, and test the pump impeller for free movement before ordering any parts.
Common Causes
- Clogged drain pump filter or coin trap (~45%) Lint, coins, hairpins, and debris accumulate in the filter and prevent water from reaching the pump.
- Kinked, crushed, or blocked drain hose (~25%) The external drain hose may be bent, inserted too far into the standpipe, or blocked by foreign objects.
- Obstructed or failing drain pump (~15%) Socks, small garments, or debris can jam the impeller, or the pump motor itself may have seized or failed electrically.
- Clogged internal sump or tub-to-pump hose (~10%) An internal hose between the tub sump and the pump housing can collect lint and restrict flow even when the filter appears clean.
- Pressure-sensing hose or sensor fault (~5%) If the tub is actually empty but the code persists, the pressure hose may be kinked, disconnected, or clogged, or the sensor itself may have failed.
Quick Diagnosis
Answer these to narrow it down fast.
Does water drain slowly or not at all when you run a drain/spin cycle?
No: The tub may be draining but the machine cannot confirm it. Check the pressure-sensing hose and sensor for kinks, blockage, or disconnection.
Can you spin the drain pump impeller freely by hand (filter removed, power off)?
No: The impeller is jammed by debris or the pump has seized. Clear the obstruction or replace the pump.
Does the error clear after cleaning the filter and drain hose?
No: Inspect the pump, internal hoses, and pressure circuit. If all check out, the control board or pump may need replacement.
Step-by-Step Fix
- Unplug the washer and turn off the water supply before opening any panels or touching the pump area.
- Open the lower front access door and place a shallow pan underneath. Drain any residual water through the emergency drain hose if your model has one.
- Remove and clean the drain pump filter (coin trap) thoroughly under running water, clearing all lint, coins, and debris.
- Inspect the external drain hose for kinks, crushing, blockage, or incorrect standpipe depth. Straighten or clear as needed.
- Check the drain pump impeller by removing the filter and shining a light into the pump housing. Spin the impeller by hand to confirm it rotates freely and is not obstructed.
- Remove and clear the internal sump hose if the filter and external hose are clean but drainage is still poor. Access this hose by tilting the washer back or removing the pump assembly.
- Test the drain pump electrically with a multimeter if it is mechanically clear but does not run. Consult your model’s wiring diagram for resistance values. Replace the pump if defective.
- Inspect the pressure-sensing hose and air trap if the tub drains completely but the code persists. Look for kinks, blockage, or disconnection. Clean or replace as needed.
- Reassemble all parts, plug in the washer, and run a drain/spin cycle to confirm the code is gone.
Parts Often Needed
| Part | Notes |
|---|---|
| Drain pump assembly | Amazon | Verify your model number; pump connectors and mounting vary by series. |
| Drain hose | Amazon | Measure length and diameter; some models use a corrugated or smooth hose. |
| Pressure hose or air trap | Amazon | Inspect the existing hose first; replacement is only needed if cracked or permanently kinked. |
When to Call a Pro
Call a professional if you have cleaned the filter, cleared the drain hose, verified that the pump impeller spins freely, and tested the pressure circuit, yet the 5C code returns. A technician can test the pump motor and wiring with precision tools, inspect internal hoses that require partial disassembly, and diagnose control-board faults. Also call if you are uncomfortable working around electrical connections or tilting the washer to access internal components. Professional service typically includes a full drainage-system inspection, pump replacement if needed, and a test cycle to confirm the repair.
Rough cost: DIY runs about $15–50 in parts (if pump replacement needed), 30–90 min. A pro service call runs about $150–300 for service call and pump replacement.
