Samsung Error Code 5C: What It Means and How to Fix
If you see a 5C error on your Samsung washer, the machine is telling you it can’t drain water properly. The code usually points to a blocked drain pump filter, a clogged or kinked drain hose, or a failed pump. Most of these issues you can fix yourself in under 30 minutes without special tools. A quick way to narrow it down: if the code appears within the first two minutes of the drain phase, the filter is the most likely culprit. Start with the first check below before going deeper.
First Check: Simple Pass/Fail Checks Before Diving In
Run through these five checks before taking anything apart. Each one gives a clear pass or fail result and points you to the right next step.
- Drain hose kinked or pinched? – Walk behind the washer and inspect the full hose run. If it’s twisted, crushed against the wall, or pushed more than 6 inches into the standpipe → Fail. Straighten it or reposition the hose, then retest.
- Standpipe or sink drain clear? – Pour a bucket of water into the drain pipe. If water backs up → Fail. Your home drain is clogged, not the washer. Call a plumber.
- Washer overloaded? – Open the door and see if the drum is packed tight. If clothes fill more than ¾ of the drum → Fail. Remove half the load and run a drain-only cycle.
- Power cycle performed? – Unplug the washer for 60 seconds and plug back in. Run a rinse & spin cycle. If the code clears → Pass, but the underlying cause may still be present (see next step).
- 5C error returns after reset? – After the power cycle, if the code reappears mid-cycle → Fail. The problem is mechanical, not a temporary glitch.
If all checks pass and the code persists, move to the step-by-step fixes below. Here’s a branching point: if you cleared the code with a power cycle but it returns during the next drain phase, skip the reset step and go straight to cleaning the drain pump filter. That pattern confirms a physical blockage, not an electrical glitch.
Step-by-Step Fix: How to Clear the 5C Error
What you need: a flat-head screwdriver (or coin), a small towel or shallow pan, and a pair of pliers. No multimeter is required for this first round of fixes.
Step 1: Clean the Drain Pump Filter
The filter is behind a small hatch at the bottom front of the washer. This is the most common cause of the 5C error, and cleaning it resolves the issue in about 80% of cases.
- Open the hatch – you may need to press a tab or slide a panel.
- Place the towel or pan underneath to catch any water (expect up to a cup).
- Turn the filter cap counterclockwise and pull it out.
- Pick out lint, coins, hairpins, or debris that may be blocking water flow.
- Rinse the filter under hot water and reinstall it (hand-tighten only – overtightening cracks the housing).
- Close the hatch and run a rinse & spin cycle.
Common mistake: Forgetting to empty the water first. If you don’t place a towel, water will spill onto the floor. Also, some Samsung models have a small drain hose next to the filter; pull that hose into the pan, remove the plug, and let the water drain before opening the filter.
Step 2: Inspect the Drain Hose for Blockage
If the filter was clean but the code remains, the hose itself may be clogged.
- Disconnect the hose from the back of the washer (behind the rear panel or at the pump outlet).
- Use pliers to loosen the clamp, then pull the hose off. Look inside for a sock, small cloth, or built-up debris.
- Straighten the hose and flush it with a garden hose or by pouring water through it.
What to expect: A fully blocked hose will often cause the 5C code within the first two minutes of the drain phase. If the hose is clear, the problem is likely the drain pump or its electrical connection.
Step 3: Check the Drain Pump for Obstruction
The pump is mounted near the bottom of the washer, accessible after removing the front kickplate or the rear access panel.
- Unplug the washer first.
- Remove the pump’s inlet hose (the one coming from the tub).
- Look inside the pump housing for foreign objects – a bra wire or piece of plastic can jam the impeller.
- Spin the pump impeller by hand; it should turn freely. If it grinds or won’t move, replace the pump.
Stop signal: If you find a broken impeller blade or the pump motor feels hot to the touch after a short run, stop troubleshooting and replace the pump. Attempting to clean a motor that has failed electrically will not fix the code.
Step 4: Verify the Fix Before Moving On
After completing any of the steps above, run a short rinse & spin cycle (no laundry). Listen for the pump to start within 30 seconds of the cycle beginning. You should hear a steady humming sound, not a clicking or grinding noise. When the cycle ends, open the door and confirm no standing water remains in the drum. If water is still present or the 5C code reappears, the issue is not resolved – proceed to the deeper checks below. If the cycle finishes cleanly with the code clear, the fix worked.
Common Causes and Quick Fix Summary
| Symptom | Most Likely Cause | What to Check | Best Fix |
|---|---|---|---|
| Code appears immediately after starting a drain cycle | Clogged filter | Remove and inspect the drain pump filter | Clean or replace filter |
| Code appears several minutes into the cycle | Obstruction in the drain hose or pump impeller | Disconnect hose, inspect pump inlet | Remove debris or replace pump |
| Code appears after the load has been sitting full of water for hours | Swollen drain hose or faulty pump solenoid | Check hose for kinks; test pump electrical continuity with a multimeter | Straighten hose or replace pump |
According to Samsung’s safety guidelines, always disconnect the washer from the power outlet before performing any diagnostic checks or repairs. Even when the machine is off, capacitors can hold a charge.
When the Quick Fixes Don’t Work
If you’ve cleaned the filter, checked the hose, and confirmed the pump spins freely but the 5C error still appears, the issue may be electrical or electronic. These three scenarios require a different approach:
Pressure switch failure – The machine uses a pressure sensor (air tube) to know when the tub is empty. If the tube is cracked or disconnected, the control board never gets the “drum empty” signal and kills power to the pump. Check the plastic hose from the bottom of the tub to the pressure chamber; reconnect or replace it. For similar sensor-related issues, see our guide on understanding the 4c error code on samsung washing machines.
Control board fault – A failed relay or burnt trace on the main PCB can stop the pump from receiving voltage. This is less common but plausible after a power surge. If you have a multimeter, measure for 120V at the pump connector during the drain cycle. No voltage means a board issue. After replacing a pump or completing a repair, you may need to know how to reset samsung washer after error code.
Failed drain pump – Even if the impeller turns freely, the pump motor windings could be shorted. Use a multimeter set to ohms; a working pump should read between 10 and 100 ohms across the two terminals. Open circuit (OL) means a dead pump. For a different brand scenario, refer to our guide on understanding the 5d error code on whirlpool washing machines.
For any of these, consider whether the cost of a service call (typically $150–$250 plus parts) justifies replacing the machine, especially if the washer is over eight years old.
Frequently Asked Questions
Q: Can I reset the 5C error by unplugging the washer?
A short reset (unplug for 60 seconds) will clear the code from the display, but if the underlying drain problem is not fixed, the error will return once the machine tries to drain. Use the reset only as a diagnostic step, not as a permanent fix.
Q: Is it safe to run the washer with the 5C error if I let it sit?
No. Running the washer when it can’t drain can cause water to overflow inside the cabinet, damage the motor (which may overheat if it keeps trying to turn the tub in standing water), or flood your floor. Always resolve the drain issue before using the machine again.
Q: Should I replace the drain pump myself?
Yes, if you are comfortable removing a few screws and disconnecting two hoses and a wiring harness. Samsung pumps are modular and cost $30–$70. Watch the orientation of the rubber boot seal when reassembling to avoid leaks. If your model has a molded pump housing that requires disassembling the entire washer, consider hiring a pro.
