The washer's control boards lost communication with each other - a sensor/communication error. The washer usually will not run until this is resolved.

Quick answer: Samsung washing machine error code AE: control board communication failure. The most common cause is loose wiring harness between control boards. Try this first — power-cycle the washer. If that does not clear it, try one restart, then stop. If the code persists, call a qualified technician.

What causes the AE error?

  • Loose wiring harness between control boards
  • Failed main control board
  • Failed sub or sensor board
  • Corroded or damaged board connectors
  • Power surge damaging the electronics

How to fix Samsung AE — step by step

Work through these in order, from simplest and safest first. Stop as soon as the code clears.

  1. Power-cycle the washer
    Unplug the washer or flip its breaker off for 2 to 3 minutes, then restore power and try a cycle. Communication glitches from power dips often clear with a full reset.
  2. Try one restart, then stop
    If AE returns immediately after a proper power cycle, the fault is hardware - a board or harness problem that resets cannot fix.
  3. Note when the code appears
    Record whether AE shows at power-on or mid-cycle and photograph the display. That detail helps the technician identify the failing board.

When to call a technician

Stop and call a qualified technician if any of these apply:
  • AE returns after a full power cycle
  • The board harness needs inspection
  • A control board needs testing or replacement
  • Connectors show corrosion or burn damage

Frequently asked questions

Can I fix AE myself?

Beyond a power cycle, no. The boards and harnesses are inside the machine and diagnosis needs live-voltage testing - technician work.

Did a power surge cause my AE?

Possibly - surges are a common cause of board communication failures. Mention any recent outage to the technician.

Will the washer run at all with AE?

Usually not. The control cannot coordinate the cycle without board communication, so it stays locked out.
