Samsung Top Load Washer Error Codes

🔧 Common Samsung Top Load Washer Error Codes

Below you’ll find the most common Samsung top load washer error codes, their symptoms, and detailed troubleshooting steps for each issue.

1C / 1E Error – Water Level Sensor Fault

Symptom:
The washer displays 1C or 1E on the control panel.

Causes:
Faulty water level sensor, loose wiring, or PBA malfunction.

Troubleshooting Steps:

  1. Check Error History
    • Power on washer → Press Delay End until “17h” appears.
    • Hold Start/Pause for 7 seconds until “AS” appears.
    • Press the first button on the bottom right to view error history.
  2. Run Rinse + Spin Cycle
    • Frequency value (no load) should be 25–26 kHz.
    • Replace the water level sensor if abnormal.
  3. Inspect Wiring
    • Check harness connections and resistance (Pin 1–3 ≈ 15–35Ω).
    • Replace if open.
  4. Check Harness Resistance
    • All wires should be below 2Ω.
  5. If Unresolved: Replace Main PBA.

3C / 3E Error – Motor or Hall Sensor Fault

Symptom:
Washer displays 3C or 3E during spin cycle.

Causes:
Motor, hall sensor, or main PCB connection issue.

Fix Steps:

  1. Check Smart Install mode for recent codes.
  2. Run Spin Only cycle – if error doesn’t occur, advise customer not to overload washer.
  3. Inspect hall sensor and motor wiring.
  4. Remove rotor and check for metal debris or burnt coils.
  5. Replace motor or main PBA if issue persists.

4C / 4E Error – Water Supply Issue

Symptom:
Washer shows 4C or 4E.

Likely Causes:

  • Water faucets not fully open.
  • Hose kinked, clogged, or incorrectly installed.

Fix Steps:

  1. Verify water faucets are open and hoses are straight.
  2. Clean water inlet filters.
  3. Ensure drain hose screws are installed (to prevent auto draining).
  4. Run Rinse + Spin → Check water level frequency (25–26 kHz).
  5. Test valve resistance (≈1KΩ) and wire harness (<2Ω).
  6. If unresolved → Replace Main PCB.

4C2 / 4E2 Error – Hot/Cold Water Reversed

Symptom:
4C2 or 4E2 appears during wash.

Fix:
Ensure hot water faucet connects to hot valve, and cold faucet connects to cold valve. Reconnect hoses properly.

5C / 5E Error – Drain Problem

Symptom:
Water not draining or error code 5C/5E appears.

Causes:
Clogged hose, blocked pump, or defective drain motor.

Fix Steps:

  1. Ensure drain hose height: Min 39″ (99cm) / Max 96″ (245cm).
  2. Clean pump and hose.
  3. Check pump resistance (13–16.5Ω) and voltage (≈120V).
  4. Replace drain pump or main PCB if faulty.
  5. Verify water level sensor hose for kinks or holes.

8C / 8E or 8C1 / 8E1 Error – MEMS Sensor Fault

Symptom:
Vibration or MEMS sensor error displayed.

Fix Steps:

  1. Check wire connection at bottom of tub.
  2. If unresolved, replace MEMS sensor, wire harness, or main PBA.

Note: On some models, MEMS sensor is integrated into PBA.

dC / dE Error – Door Error

Symptom:
Washer won’t start or displays dC/dE.

Fix Steps:

  1. Ensure door is fully closed before pressing Start.
  2. Check door switch wiring (Normal: Closed <2Ω / Open ∞Ω).
  3. Inspect harness (Resistance <2Ω).
  4. Replace Door Switch or Main PBA if needed.

LC / LE Error – Leak Detected

Symptom:
Washer detects water leakage.

Fix Steps:

  1. Check drain hose for holes or improper installation.
  2. Inspect tub, pump, and hose connections for leaks.
  3. Verify water level sensor hose (frequency ≈25–26kHz).
  4. Replace leaking parts or defective sensor.

OC / OE Error – Overflow or Overfill

Symptom:
Washer fills continuously or displays OC/OE.

Fix Steps:

  1. If water fills when power is off → Replace water valve.
  2. Check water level sensor frequency (25–26kHz).
  3. Inspect sensor hose for holes.
  4. If valve relay is shorted, replace main PBA.

Ur / UB Error – Unbalanced Load

Symptom:
Excessive vibration or “Ur/UB” error during spin.

Troubleshooting:

  1. Ensure washer is installed on solid, level surface.
  2. Level the unit front-to-back and side-to-side.
  3. Avoid drain pans, rugs, or slippery flooring.
  4. Check basket alignment – replace if wobbling.
  5. Inspect motor, clutch, hall sensor, and dampers.
  6. Grease or replace damaged dampers (Grease P/N: 0205-001283).

bC / bE Error – Button Stuck or Control Fault

Symptom:
bC/bE appears and controls don’t respond.

Fix Steps:

  1. Check for stuck buttons or deformed control panel.
  2. Replace Sub PCB if panel is normal.
  3. Verify contact resistance (Normal: 0Ω when pressed).

AC / AE Error – Communication Error

Symptom:
AC/AE displayed on control panel.

Fix Steps:

  1. Reconnect main and sub PCB harnesses.
  2. Replace wire harness if damaged.
  3. Replace sub PCB, then main PCB if error persists.

🧰 Final Tips

  • Always check error history using Smart Install mode before servicing.
  • Keep hoses clear, wiring connected firmly, and ensure all sensors read proper values.
  • Replace Main PBA last, after verifying all other components.

  1. What does the 1C or 1E error code mean on a Samsung top load washer?

    samsung washer level sensor

    The 1C or 1E error indicates a problem with the water level sensor. Check the wiring harness and sensor connections, measure the signal frequency (normally around 25–26 kHz), and replace the water level sensor or main PCB if necessary.

  2. How do I fix the 4C or 4E water supply error on my Samsung washer?

    samsung washer inlet valve

    This error means your washer is not getting enough water. Make sure both water faucets are open, hoses are not kinked, and inlet filters are clean. If water still doesn’t fill, check the inlet valve resistance (around 1KΩ) and wire connections.

  3. Why does my Samsung washer show the 5C or 5E drain error?

    samsung washer drain pump

    The 5C or 5E code indicates a drainage issue. Check for a clogged or kinked drain hose, clean the pump filter, and ensure the drain hose height is between 39 and 96 inches. If the pump resistance isn’t between 13–16.5Ω, replace the drain pump.

  4. What causes the 3C or 3E motor error on Samsung top load washers?

    samsung washer motor

    This error is caused by a malfunctioning motor or hall sensor. Reconnect the motor and PCB wiring, check for metal debris on the rotor, and replace the motor or main PCB if the problem continues.

  5. What does the 8C or 8E sensor error mean on a Samsung washer?

    This means the lid is not properly closed. Make sure it’s shut, check the door switch and harness for continuity (2Ω or less when closed), and replace the door switch or PCB if faulty.

  7. What should I do if my Samsung washer shows LC or LE leak error?

    samsung washer leak hose connection

    The LC or LE error indicates a water leak or overflow. Inspect all hoses and tub for leaks, check the water level sensor and hose for damage or kinks, and replace any faulty components.

  8. What does the Ur or UB unbalanced load error mean?

    samsung washer ub error

    This error means the washer load is unbalanced. Level the washer, avoid washing single heavy items, and ensure it’s on a stable floor. Replace suspension rods or the basket if vibration continues.

  9. How do I fix the bC or bE button error on my Samsung washer?

    samsung washer BE error

    A bC or bE code happens when a control button is stuck or shorted. Free any stuck buttons, inspect the control panel, and replace the sub PCB if needed.

  10. What does the AC or AE communication error mean?

    The AC or AE code indicates a communication failure between the main PCB and sub PCB. Check and reconnect the harness; replace the sub PCB or main PCB if the issue persists.
