Samsung Washer 5C Error Code — What It Means
On Samsung washers, the 5C error code signals a drainage fault. The machine detects that water is not draining normally or not draining fast enough, so the control system flags a long-drain condition. In practice, this means water remains in the tub longer than expected, triggering the error.
Samsung documentation also describes 5C as a control-board alert when the sensed water-level feedback is outside the expected range, which is consistent with the washer believing water still sits in the drum even after a drain cycle. The code stops the cycle to prevent overflow or damage.
Before You Replace Anything
Many people replace the drain pump assembly before checking the filter and hose. Clean the pump filter and inspect the drain hose for kinks first-those two steps clear most 5C codes without any new parts.
Common Causes
- Clogged pump filter or coin trap (~50%) Lint, coins, buttons, and small debris collect in the filter housing and block water flow to the pump.
- Kinked, crushed, or blocked drain hose (~25%) The drain hose is bent sharply, pinched behind the machine, inserted too far into the standpipe, or clogged internally.
- Drain pump obstruction or pump failure (~15%) Foreign objects jam the pump impeller, or the pump motor itself has failed and no longer spins.
- Internal sump hose clog (~7%) The short hose between the tub and the pump housing is blocked by fabric, sludge, or debris.
- Pressure sensor or wiring fault (~3%) The washer drains normally but the pressure hose, sensor, or control-board connection is damaged, so the machine still believes water remains.
Quick Diagnosis
Answer these to narrow it down fast.
Is there standing water in the drum?
No: Water is draining but the washer still throws 5C. Suspect a pressure-sensor or wiring issue after you confirm the filter and hose are clear.
After cleaning the filter, does a drain/spin test complete without the 5C code?
No: Inspect the drain hose path and then access the pump and sump hose for internal obstructions or pump failure.
Can you hear the drain pump running during the drain cycle?
No: The pump may have failed, or it has lost power due to a wiring or connector problem.
Step-by-Step Fix
- Power off and unplug the washer before any service work to prevent shock or accidental start.
- Manually drain remaining water by pulling the emergency drain hose or slowly unscrewing the pump filter cap into a shallow pan.
- Remove and clean the drain pump filter by unscrewing the access panel (usually lower front), turning the filter cap counterclockwise, and flushing out coins, lint, buttons, and debris under running water.
- Inspect the drain hose from the back of the washer to the standpipe or laundry sink: straighten any kinks, confirm the hose isn’t crushed, check that the standpipe insertion depth matches the owner’s manual (typically no more than 8 inches), and feel along the hose for internal blockage.
- Run a drain/spin test cycle to see if the 5C code clears after cleaning the filter and hose.
- If the code returns, tip or lay the washer forward to access the sump hose (the short internal hose between tub and pump), disconnect it, flush it clear, and check the pump impeller for jammed objects or damage.
- Replace the drain pump assembly if the impeller won’t turn, the motor doesn’t hum, or you find visible damage to the pump housing or wiring connectors.
- Check the pressure hose and sensor if the washer drains completely but still flags 5C: disconnect the small air hose from the pressure switch, blow through it to confirm it’s clear, and inspect the switch connector for corrosion or loose pins.
Parts Often Needed
| Part | Notes |
|---|---|
| Drain pump assembly | Amazon | Match your Samsung model number; many front-load models share the same pump design. |
| Drain hose | Amazon | Measure length and diameter before ordering; some hoses include the elbow fitting. |
| Pump filter cap and housing | Amazon | If the threads are stripped or the cap won’t seal, replace the entire filter assembly. |
When to Call a Pro
Call a professional if you’ve cleaned the filter, cleared the hose, and confirmed the pump runs but the 5C code still appears. At that point the fault may involve internal sump-hose access (requiring the washer to be tipped or partially disassembled), pump replacement with correct hose routing, or diagnosis of the pressure-sensor circuit and control-board connections. Also call if you find water leaking from the pump area during testing, since that can indicate a cracked pump housing or loose clamp that needs hands-on assessment. If you’re not comfortable working with electrical connectors or don’t have a helper to safely tip a front-load washer, a technician can complete the repair in one visit with the correct parts on the truck.
Rough cost: DIY runs about $15–50 in parts if a hose or pump is needed, 30–60 min. A pro service call runs about $150–250.
