Samsung Washer-Dryer Combo Error Codes: Complete List with Fixes

Samsung combo washer-dryer units — including the Bespoke AI All-in-One (WF53BB8700AT), the WD6500T, and the compact WD-series — combine a full washing machine and a ventless heat-pump or condensation dryer in a single unit. This convenience comes with a more complex error code system that covers both washing and drying functions, plus combo-specific codes that do not appear on standalone machines. This guide covers every error code, explains whether it relates to the wash or dry cycle, and provides step-by-step fixes.

How Samsung Combo Error Codes Work

Samsung combo units monitor everything a standalone washer monitors (water level, drain, motor, door, temperature) plus everything a dryer monitors (exhaust temperature, condenser, heat pump, moisture sensor). Additionally, combo-specific codes address the condenser water tank, the heat exchanger, and the transition between wash and dry cycles.

Error codes appear on the LED display. Some codes are shared with standalone Samsung washers (4C, 5C, UE, dE, etc.) and behave identically. Others are combo-specific (cL, HC, Cd). This guide focuses on the combo-specific codes and the most common shared codes with combo-relevant diagnostic tips.

To reset most Samsung combo error codes:

1. Press Start/Pause to pause the cycle.
2. Press Power to turn off the unit.
3. Unplug for 2 minutes, then restore power.
4. Run a short wash cycle (Quick Wash) to test the washer function, then a short dry cycle (Time Dry 30 min) to test the dryer function.

4C / 4E / nF — Water Supply Error (Wash Cycle)

The unit cannot fill with water during the wash cycle.

Common causes:

• Water supply valves closed or partially closed
• Inlet hose kinked (common in tight combo installations — these units go in closets and tight laundry spaces)
• Inlet screen clogged with mineral deposits (Samsung DC62-00142G valve assembly)
• Low water pressure (below 14.5 PSI) — particularly common in multi-story apartments where combos are popular

How to fix:

1. Check both hot and cold water valves are fully open.
2. Disconnect inlet hoses and clean the mesh filter screens at the valve inlets. Hard water areas like Sacramento and the Bay Area clog these screens in 1–2 years.
3. Check for kinks — combo units are often installed in tight spaces where hoses get pinched.
4. Test water pressure: hold a bucket under the hot water hose with the valve open. It should fill a gallon in under 30 seconds. Slower = low pressure issue.

Part cost: Water inlet valve (DC62-00142G) $25–$50. New braided stainless fill hoses $15–$25/pair. Professional repair $100–$250.

5C / 5E — Drain Error (Wash Cycle)

The unit cannot drain water from the tub during or after the wash cycle.

Common causes:

• Clogged drain pump filter (the #1 cause on all Samsung washers)
• Kinked drain hose (very common in closet installations)
• Drain pump failure (Samsung DC31-00054A)
• Drain hose inserted too far into the standpipe (causes siphoning)

How to fix:

1. Open the small access door at the bottom-front. Place towels and a shallow pan underneath. Slowly turn the filter cap counterclockwise.
2. Clean the filter of lint, coins, hair pins, and debris. Also look inside the pump housing with a flashlight.
3. Check the drain hose — in combo installations, the hose often gets compressed behind the unit. Ensure 6–8 inches of insertion into the standpipe.
4. If the filter is clean and hose is clear, the drain pump motor may be failed. It should hum when powered — no hum = motor failure.

Part cost: Drain pump (DC31-00054A) $25–$50. Professional repair $100–$250.

UE / E4 / Ub — Unbalanced Load

The combo detects an unbalanced drum during the spin cycle.

Common causes:

• Single heavy item (comforter, jeans) bunched on one side
• Combo units are more sensitive to imbalance than standalone washers because they are often installed on pedestals or in closets where vibration tolerance is lower
• Worn shock absorbers (Samsung DC66-00470A) — combo units vibrate more due to the heavier drum assembly
• Unit not level on the floor

How to fix:

1. Open the door and redistribute the load evenly.
2. Add towels if washing a single large item.
3. Check that the unit is level on all four feet. Combo units on pedestals must have both the pedestal and the unit leveled.
4. If UE appears on every load, inspect the shock absorbers — combo units have heavier drums that wear shocks faster than standalone washers.

Part cost: Shock absorber pair (DC66-00470A) $20–$40. Suspension rod kit (DC97-16350C, top-load combos) $15–$30. Professional repair $75–$225.

dE / Ed / dE1 / dE2 — Door Error

The door is not properly closed or the latch has failed.

Common causes:

• Clothing caught in the door gasket
• Door lock assembly failure (Samsung DC64-00519D)
• Door lock wax motor weak — works when warm (afternoon) but fails when cold (morning)
• Door strike plate bent from pulling door open too hard

How to fix:

1. Open the door fully and check the gasket for trapped items.
2. Close firmly until you hear a click.
3. Inspect the door strike and latch receiver for damage.
4. If the lock buzzes but does not engage, the wax motor in the lock assembly is weak — replace the lock assembly (DC64-00519D).

Part cost: Door lock assembly (DC64-00519D) $25–$50. Door strike plate (DC66-00326A) $10–$20. Professional repair $125–$275.

HC / hE — Dryer Overheating (Dry Cycle)

The dryer section detects exhaust temperature above the safe threshold during the drying phase.

Common causes:

• Condenser lint filter clogged (combo-specific — this filter is separate from the wash drain filter)
• Heat exchanger clogged with lint (on condensation-type combos)
• Ventless heat pump condenser coils dirty (on heat-pump combos like the Bespoke AI)
• Ambient temperature too high for efficient condensation drying

How to fix:

1. Clean the condenser lint filter: On Samsung combo units, there is a separate lint filter accessible from inside the door opening or from a panel at the front-bottom. This filter must be cleaned after every drying cycle.
2. Clean the heat exchanger: On condensation combos, remove the lower access panel and rinse the heat exchanger plates with water. Lint accumulates between the plates and blocks airflow.
3. Clean heat pump coils: On heat-pump combos (Bespoke AI series), access the heat pump coils from the lower front panel. Vacuum lint from the coils gently.
4. Ensure the room has adequate ventilation — ventless combos release humidity into the room and need at least 4 inches of clearance on all sides.

Part cost: Condenser lint filter $15–$30 (if damaged). Heat exchanger cleaning: free. Professional heat pump coil cleaning $100–$200.

tE / EC — Temperature Sensor Error (Either Cycle)

The thermistor for the wash or dry cycle is reading abnormally.

Common causes:

• Wash thermistor failure (Samsung DC32-00007A) — same as standalone washer
• Dry cycle thermistor failure — additional sensor monitoring exhaust air temperature
• Wiring harness issue between sensors and control board
• tE1 = wash thermistor open; tE2 = wash heater thermistor; tE3 = dry cycle exhaust sensor

How to fix:

1. Determine which cycle triggers tE — wash cycle or dry cycle — to identify which sensor is at fault.
2. For wash thermistor: approximately 10–12 k-ohm at room temperature. Test by removing the rear panel.
3. For dry thermistor: access from the lower front panel. Similar resistance range.
4. Check wiring connectors — combo units have more wiring harnesses in a compact space, and connectors can vibrate loose.

Part cost: Thermistor (DC32-00007A) $10–$20. Professional repair $125–$275.

cL — Condenser Water Tank Full (Combo-Specific)

The condensation collection tank that captures water extracted during ventless drying is full and must be emptied.

Common causes:

• Tank not emptied after previous drying cycles (the #1 cause)
• Tank float switch stuck (thinks tank is full when it is not)
• Drain pump for the condensation tank failed (on models with auto-drain)
• Condensation tank not seated properly after cleaning

How to fix:

1. Remove the condensation tank (usually a pull-out drawer at the top or front of the unit). Empty the water and clean the tank.
2. Check the float switch inside the tank — it should move freely. If stuck by mineral deposits, clean with vinegar.
3. On models with auto-drain to the wash drain hose, check that the auto-drain pump is functioning. Run a dry cycle and listen for the drain pump to activate periodically.
4. Reinstall the tank and ensure it is fully seated — a misaligned tank triggers cL even when empty.

Part cost: Float switch $10–$20. Auto-drain pump $25–$50. Professional repair $75–$175.

Cd — Dry Cycle Complete (Not An Error)

This is not an error code — "Cd" indicates the drying cycle has completed successfully. The display shows Cd along with a cool-down period indicator.

No fix needed. Remove your clothes promptly to prevent wrinkles. If the clothes are still damp after Cd appears, the dryer portion is underperforming — check for clogged condenser filter (see HC section) or select a longer drying time.

3C / 3E — Motor Error

The motor cannot turn the drum during either wash or dry cycles. Combo units use a single motor for both functions.

Common causes:

• Hall sensor failure (Samsung DC31-00098A) — the #1 cause, detects motor position
• Motor overloaded (drum too full — combo units have smaller capacity than standalone)
• Motor winding failure (Samsung DC31-00111A)
• Motor control board fault (Samsung DC92-01531A)
• 3E1 = overload; 3E2 = low current; 3E3 = Hall sensor; 3E4 = inverter board

How to fix:

1. Reduce the load. Combo units typically have 2.2–4.5 cu ft capacity — overfilling is the most common cause.
2. Unplug and run a calibration cycle: hold Delay End + Soil Level for 3 seconds on most Samsung models.
3. Check the Hall sensor on the motor (5 thin wires, mounted at the motor rear). Test between adjacent pairs — should read 10–15 ohms.
4. If the Hall sensor tests good, check motor windings: each phase should read 4–8 ohms.

Part cost: Hall sensor (DC31-00098A) $10–$25. Motor (DC31-00111A) $60–$120. Professional repair $200–$450.

9C1 / 9C2 — Voltage Error

The power supply voltage is outside the acceptable range.

Common causes:

• Combo units are 240V (like dryers) and require a NEMA 14-30 outlet
• Half-tripped breaker delivering only 120V
• Extension cord voltage drop (never use extension cords for combo units)
• 9C1 = overvoltage; 9C2 = undervoltage

How to fix:

1. Measure outlet voltage — should read 240V AC between the two hot legs.
2. Turn the breaker fully off and fully on.
3. Plug directly into a dedicated wall outlet — combo units draw significant current during the dry cycle heater phase.

Part cost: Typically no parts needed. Power cord replacement $15–$25 if damaged.

Samsung Combo Diagnostic Mode

Samsung combo washer-dryers have specific diagnostic features:

1. SmartThings App Diagnosis (Wi-Fi models): Open SmartThings, select your combo unit, tap Device Care > Self Check. The app tests both wash and dry systems and reports status for each.

2. Calibration Mode: Hold Delay End + Soil Level for 3 seconds (model-specific). The unit runs a calibration cycle that sets motor parameters for the specific installation (important for combo units on pedestals or uneven floors).

3. Component Test Mode: Power on the unit. Press and hold Temp + Rinse for 3 seconds. The unit cycles through: door lock, fill valve, drain pump, motor (low speed), motor (high speed), heater. Observe which component fails.

4. Dry-Only Diagnostic: Run a 30-minute Time Dry cycle with a damp towel. The exhaust should be warm and the towel should be noticeably drier. No heat output points to a dry-side heater or heat pump issue.

5. Condensation Efficiency Test: On ventless models, run a full dry cycle with a known-weight wet load. The condensation tank should capture approximately 80% of the water removed. Significantly less suggests a heat exchanger or condenser issue.

Frequently Asked Questions

Q: My Samsung combo washes fine but does not dry — what code should I look for? A: If no code is displayed, the most common issues are: clogged condenser lint filter (clean it after every dry cycle), clogged heat exchanger plates, or the room being too warm/humid for effective condensation drying. Samsung combos dry using condensation or heat pump technology, not a vented exhaust, so room conditions matter. Optimal drying performance requires room temperature below 80 degrees F and good ventilation.

Q: Why do Samsung combo washer-dryers take so long to dry? A: Ventless drying (condensation or heat pump) is inherently slower than vented drying because it extracts moisture through condensation rather than exhausting hot humid air directly outside. A typical combo dry cycle takes 2–3 hours for a full load compared to 45–60 minutes for a vented dryer. Reduce drying time by: using the highest spin speed during wash (extracts more water), washing smaller loads, and cleaning the condenser filter after every cycle.

Q: Can I stack my Samsung combo washer-dryer? A: Samsung combo units are all-in-one — they do not need stacking because wash and dry happen in the same drum. If you mean stacking with a separate pedestal, yes — Samsung makes matching pedestals (model-specific). Ensure both the pedestal and the unit are perfectly level, as combo units are heavier and more prone to vibration than standalone washers.

Q: Do I need a special outlet for a Samsung combo washer-dryer? A: Yes. Samsung combo washer-dryers require a 240V outlet (NEMA 14-30), the same as a standalone electric dryer. A standard 120V washer outlet will not work. This is the #1 installation surprise for customers upgrading from a standalone washer.

Q: How often should I clean the condenser filter on my Samsung combo? A: After every drying cycle. This is the single most important maintenance task for combo units. A clogged condenser filter is the #1 cause of poor drying performance and the HC overheating code. Unlike a vented dryer's lint screen (which most people clean regularly), the condenser filter is less visible and often forgotten.

When to Call a Professional

Samsung combo washer-dryers combine the complexity of both appliances in a compact space, making some repairs more challenging:

• 3C with free-spinning drum — Motor or inverter board diagnosis in a combo requires testing both wash and dry modes.
• HC after condenser cleaning — If the heat exchanger or heat pump coils are clear but HC persists, the condenser fan or heat pump compressor may be failing.
• tE3 (dry exhaust sensor) — Accessing the dry-cycle sensor in a combo requires more disassembly than in a standalone dryer.
• Repeated cL with empty tank — The auto-drain pump or float switch mechanism needs diagnosis in a tight space.
• Refrigerant-related issues (heat pump models) — The Bespoke AI heat pump uses refrigerant for the drying cycle. Leaks or compressor issues require EPA-certified repair.
• Any error affecting both wash and dry cycles — Likely a control board, power supply, or motor issue that requires professional multi-system diagnosis.
