Samsung washing machines display error codes to alert users to specific issues, helping diagnose problems quickly without professional help in many cases. These codes appear on the control panel during operation and vary slightly by model, but common ones are consistent across front-load and top-load units.
Water Supply Errors (4C/4E, 1E, 1C)
The 4C or 4E code indicates a water supply problem, often due to low pressure, kinked hoses, or closed valves. Check that faucets are fully open, straighten inlet hoses, and clean any debris from the inlet filters by unscrewing the hoses and rinsing the screens. If unresolved, inspect the water inlet valve for faults, which may require replacement.
Similarly, 1E or 1C signals issues with water filling, like faulty sensors or blockages. Verify hose connections and pressure; run a test cycle after cleaning. Persistent codes suggest a defective pressure switch or inlet valve needing technician attention.
The 4C2 variant points to hot/cold hose mix-ups—ensure the cold hose connects to the cold inlet and hot to hot.
Drainage Issues (5C/5E, SC)
A 5C or 5E error means the machine can’t drain properly, commonly from clogged pumps, hoses, or filters. Access the front-bottom filter (pull out the lower panel), twist counterclockwise, and clean out lint or debris; run an empty drain/spin cycle afterward. Clear the drain hose of kinks or obstructions at the standpipe.
SC specifically flags drain pump failures alongside clogs. If cleaning doesn’t help, test the pump by listening for humming—replace if silent or faulty. These fixes resolve most drainage errors without tools beyond a towel for spills.
Door and Lid Problems (DC/DE, DC1)
DC or DE appears when the door fails to lock, often from misalignment, debris in the latch, or a worn strike. Ensure laundry isn’t blocking closure, clean the latch area, and realign if needed by adjusting hinges. Restart after 5 minutes to reset.
DC1 may indicate a faulty door lock assembly. Inspect wiring for damage; replacement is straightforward but involves unplugging power first for safety.
Load Balancing Errors (UB, UE)
UB or UE signals an unbalanced load, halting spins to protect the drum. Pause, redistribute clothes evenly (avoid single heavy items), and restart—add towels for small loads. Level the machine on all four feet if vibrations persist.
This prevents motor strain and is the most frequent user-fixable issue during heavy cycles.
Leak and Overflow Codes (LE, OE/OF)
LE detects leaks, shutting down to avoid flooding—check hoses, pump, or tub seals for drips and tighten connections. Tilt the machine to drain excess water safely.
OE or OF means overflow from over-sudsing or sensor faults. Use HE detergent sparingly; run rinse cycles to clear foam. Clean the pressure sensor hose if clogs are suspected.
Motor and Tachometer Errors (3C/3E, LE1)
3C or 3E points to motor overload, wiring issues, or rotor faults. Reduce load size, ensure the drum spins freely by hand (unplugged), and clean debris. Test continuity on motor wires if comfortable with multimeters.
LE1 (or LE) often means a locked/overloaded motor—similar fixes apply, but persistent cases need hall sensor replacement.
Heating Faults (HE, tE, 6E)
HE or HE1 shows heater element or thermistor problems, common in cold climates. Unplug, access the heater (rear panel), and test resistance (should be 25-50 ohms). Clean calcium buildup or replace.
tE1/tE2 indicates temperature sensor errors—reset by cooling; otherwise, replace the NTC thermistor. 6E requires pro service for heating unit issues.
Suds and Detergent Alerts (Sud, nF1)
Sud appears from excess suds slowing drainage—use less detergent (especially non-HE) and run rinse/spin. Avoid fabric softener overload.
nF1 or similar flags incorrect hoses or low suds compatibility.
Electrical and Sensor Codes (UC, bE, AE)
UC signals voltage fluctuations—use a stabilizer or check outlets. bE means stuck buttons—clean panel, avoid pressing too hard.
AE/AE6 is communication errors between modules—power cycle and check wiring harnesses.
Other sensors like CE (cooling fan) need debris clearance.
Advanced Codes (PC, SF, 8E)
Less common: PC/PE for clutch errors in top-loaders; reset or inspect clutch. SF/SF1 series (system faults) often needs firmware updates or board resets via service mode (hold Soil + Power).
8E/8E1 for current/sensor issues—cool down and retry; pro diagnosis likely.
General Troubleshooting Tips
Always unplug before inspections to avoid shocks. Enter diagnostic mode (varies: e.g., hold Spin + Soil) to replay codes. Clean monthly: filter, dispensers, and run tub clean with bleach.
For unresolved issues post-reset, note the model number and contact Samsung support—many fixes are DIY, saving costs. Regular maintenance prevents 80% of codes.
| Error Category | Common Codes | Quick Fix Summary |
|---|---|---|
| Water Supply | 4C/4E, 1E | Check hoses, valves, filters |
| Drainage | 5C/5E, SC | Clean pump/filter/hose |
| Door/Lid | DC/DE | Inspect latch, realign |
| Balance | UB/UE | Redistribute load |
| Leaks/Overflow | LE, OE | Tighten, reduce suds |
| Motor | 3C/3E, LE | Reduce load, check drum |
| Heating | HE, tE | Test element/sensor |
This covers primary codes; consult your manual for model-specific variants. Proper handling restores function fast.
