Samsung Dishwasher AE/CE Error: Communication Failure

Samsung Dishwasher AE/CE Error: Communication Failure
Quick Answer

The Samsung AE/CE error indicates the control panel cannot communicate with the main control board. Try an extended power cycle first—turn off the breaker for 5+ minutes. This error often follows power surges or outages and may clear after reset. Persistent AE/CE errors typically require professional board inspection or replacement.

Error Code AE / CE (also: None)
Meaning Communication failure between control panel and main board
Difficulty Difficult (4/5)
Time to Fix Diagnosis: 20 min; Repair: Professional
Tools Needed None for basic diagnosis

The AE or CE error code on Samsung dishwashers indicates a communication failure between the control panel (display board) and the main control board. This is an internal electronics issue that often follows power disturbances.

What the AE/CE Error Code Means

When your Samsung dishwasher displays AE (or CE on some models), the two main electronic components cannot communicate:

  • Control panel (display board): Located behind the door controls, handles user input and displays status
  • Main control board: Located in the base or door, controls all dishwasher functions

When these boards can’t communicate, the dishwasher cannot operate and displays AE or CE.

Model Coverage

This guide applies to Samsung dishwashers displaying AE or CE error codes:

  • DW80CG, DW80BB, DW80B series (2022+)
  • DW80R, DW80T series (2019-2022)
  • DW80M, DW80K, DW80J, DW80N series (2015-2020)

AE and CE are interchangeable—Samsung uses different codes on different model generations for the same issue.

Common Causes

The AE/CE error typically results from:

  1. Temporary electronic glitch following power surge or outage (most common)
  2. Loose wire connection between display board and main control board
  3. Power surge damage to one or both control boards
  4. Defective display board (front control panel)
  5. Defective main control board
  6. Water damage to board connections (rare)

Step-by-Step Diagnosis

Step 1: Extended Power Cycle

Communication errors often clear with a longer-than-normal power cycle.

  1. Turn off the circuit breaker for the dishwasher
  2. Wait at least 5 minutes (10 minutes is better)
  3. This extended time allows all capacitors to fully discharge
  4. Restore power at the breaker
  5. Turn on the dishwasher and check for error
Pro Tip

Standard 1-2 minute power cycles often don’t clear AE/CE errors because the control boards retain charge longer than other components. Always use 5+ minutes for communication errors.

Step 2: Check for Recent Power Events

AE/CE errors commonly follow power disturbances.

Consider whether any of these occurred recently:

  • Power outage (even momentary)
  • Lightning strike in the area
  • Circuit breaker trip
  • Plugging in high-draw appliance on same circuit
  • Electrical work in the home

If yes, the extended power cycle is very likely to resolve the issue.

Step 3: Test After Power Restore

After restoring power:

  1. Turn on the dishwasher
  2. Check if AE/CE error is gone
  3. If clear, select a cycle and press Start
  4. Monitor for the first few minutes
  5. If cycle begins normally, the issue was likely a temporary glitch

Step 4: Listen for Control Board Activity

When you power on the dishwasher, listen carefully:

Normal sounds:

  • One or two relay clicks from the control area
  • Display lights up
  • Responds to button presses

Abnormal signs:

  • Rapid clicking (relay chattering)—may indicate voltage or board issue
  • No clicks at all—may indicate board failure
  • Partial display (some segments lit, others not)—display board issue
  • Buttons unresponsive—communication failure continuing

Step 5: Check for Visible Damage (Advanced)

If you’re comfortable accessing the control panel area:

  1. Disconnect power at breaker
  2. Remove screws holding the inner door panel (varies by model)
  3. Carefully access the display board area
  4. Look for:
    • Loose wire connectors
    • Burnt or discolored components
    • Corrosion on connections
    • Water damage evidence
  5. If you find loose connectors, reseat them firmly
  6. Reassemble and test

Note: This requires working inside the door panel and may void warranty. When in doubt, call a professional.

Why DIY Repair Is Limited

AE/CE errors involving actual board failures require:

  • Proper diagnosis to identify which board (display or main) has failed
  • Matching replacement parts for your specific model
  • Correct reassembly of wire harnesses
  • Potential firmware considerations on smart models

Control board replacement involves careful handling of electronic components and proper connector alignment. Professional service is recommended.

Typical Repair Costs

ComponentPart CostTotal with Labor
Display board$75-150$175-275
Main control board$150-250$275-400
Wire harness$30-60$100-175

If both boards need replacement (rare), total costs can approach $500+. At that point, dishwasher replacement may be more economical.

When to Call a Tech

Contact a professional if:

  • AE/CE persists after 10+ minute power cycle
  • The error returns repeatedly (more than 2-3 times in a month)
  • You notice burnt smell from the control area
  • Display shows partial or garbled information
  • Buttons are unresponsive even when display works
  • You’re not comfortable accessing control panel components

What to tell the technician:

  • Exact error code (AE or CE)
  • Any recent power events (outages, surges)
  • Whether power cycle ever clears it temporarily
  • Any unusual sounds or smells
  • Age of the dishwasher

Preventing AE/CE Errors

  • Use a surge protector on the dishwasher circuit if possible
  • Don’t overload circuits—dishwashers draw significant power during heating
  • Address power quality issues—frequent outages or surges indicate electrical problems
  • Keep connections dry—avoid spraying water directly at the control panel

LED-Only Models

On models without digital displays, a communication error may show as all four or more indicator lights blinking simultaneously. The same troubleshooting steps apply.
