What This Error Means

Error AE on your Samsung washing machine means: The washer's internal electronic components cannot communicate with each other. A communication breakdown has occurred between the main control board and one or more subsystems. Also displayed as AE3, AE4, AE5, AE6 on some Samsung models. The washer's self-diagnostic system has detected this condition and paused the current cycle.

The most frequent cause is main control board fault or failure. Work through the causes and fix steps below in order — most Samsung washer errors are resolved without a service call.

Samsung's official guidance classifies AE as a technician-only fault. A 2–3 minute power reset is the only DIY step — if the code returns, contact Samsung Support at 1-800-726-7864.

Electronics and motor faults require professional diagnosis. A 2–3 minute power reset resolves transient faults. If the code returns after a reset, the physical component has failed and will not recover without replacement.

Most Likely Cause by Symptom

The Samsung washing machine may stop, pause, or refuse to complete the cycle normally.

Likely cause: Main control board fault or failure

Check first: SAFETY: Unplug the washer.

The warning may return immediately because the appliance is detecting an internal fault.

Likely cause: Wiring harness fault — connector loose or wire broken between boards

Check first: Reset by unplugging for 2–3 minutes, then restore power and retry.

Common Causes

  • Main control board fault or failure
  • Wiring harness fault — connector loose or wire broken between boards
  • Power surge corrupting board communication
  • Inverter board communication failure

What Not to Do

  • Do not attempt to reconnect board connectors yourself — incorrect handling poses an electrical risk
