Samsung Dishwasher AE error code

The dishwasher's main control board lost communication with the sub board (the panel electronics) - an internal communication failure. The dishwasher usually will not run a cycle.

Also shown as: AE, AC, AE6

Last updated: October 6, 2026

Quick answer: Samsung dishwasher error code AE: control board communication failure. The most common cause is loose wiring harness between the main and sub boards. Try this first — power-cycle at the circuit breaker. If that does not clear it, try one restart, then stop.

What causes the AE error?

  • Loose wiring harness between the main and sub boards
  • Failed main control board (PBA)
  • Failed sub board or control panel electronics
  • 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 at the circuit breaker
    Switch the dishwasher's breaker off for 2 to 5 minutes, then back on. Communication glitches from power dips sometimes clear with a full reset.
  2. Try one restart, then stop
    If AE returns immediately after a proper reset, the fault is hardware - a board or harness issue. Repeated resets will not fix it.
  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 which board is failing.

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 and reseating
  • The main or sub 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 door and base, and diagnosis needs live-voltage testing - technician work.

Is AE the same as CE?

They are related but different: AE is main-to-sub board communication failing; CE is the control panel failing to talk to the rest of the dishwasher. Both need a technician.

Did a power surge cause my AE?

Possibly - surges are a common cause of board communication failures. Mention any recent outage to the technician, and consider a surge protector.
