Step-by-Step DIY Fix Guide
- SAFETY: Disconnect power at the circuit breaker.
- Reset by restoring power after 60 seconds, then attempt to start a cycle.
- If CE returns, call Samsung Support at 1-800-726-7864.
If the code comes back
- CE returns after a single 60-second power reset
What This Error Means
Error CE on your Samsung dishwasher means: The dishwasher's internal electronic components cannot communicate with each other. A communication breakdown has occurred between the main control board and the display or motor control subsystem, halting the cycle. The dishwasher's self-diagnostic system has flagged this condition and may have paused the current cycle.
The most frequent cause is main control board fault or failure. Work through the causes and steps below before calling a technician.
Samsung's official guidance classifies CE as a technician-only fault. A 60-second power reset is the only DIY step. If the code returns, contact Samsung Support at 1-800-726-7864.
Communication and pump faults require professional diagnosis. A 60-second power reset resolves transient faults caused by power surges or brief interruptions. If the code returns after a reset, a physical component has failed and needs professional replacement.
Most Likely Cause by Symptom
The Samsung dishwasher may stop, pause, or refuse to complete the cycle normally.
Likely cause: Main control board fault or failure
Check first: SAFETY: Disconnect power at the circuit breaker.
The warning may return immediately because the appliance is detecting an internal fault.
Likely cause: Wiring harness connector loose or damaged between control boards
Check first: Reset by restoring power after 60 seconds, then attempt to start a cycle.
Common Causes
- Main control board fault or failure
- Wiring harness connector loose or damaged between control boards
- Power surge corrupting the board communication protocol
- Display board communication failure
What Not to Do
- Do not attempt to reconnect board connectors yourself without confirming the fault location first
- Do not run the dishwasher repeatedly with CE active — a communication fault can indicate a developing board failure

When Not to Keep Troubleshooting
CE returns after a single 60-second power reset
How to Prevent It Recurring
- Use a surge protector on the dishwasher outlet — voltage spikes are a leading cause of control board communication faults
Related Error Codes
3C
The dishwasher's wash pump has failed or is not operating within normal parameters. The pump is responsible for circulating water through the spray arms during the wash cycle. When 3C appears, the pump cannot move water and the wash cycle stops.
bE
The dishwasher's control panel has detected that one or more buttons are continuously pressed. A stuck button prevents the control panel from accepting new inputs, which halts normal operation.
AP
The dishwasher is in Wi-Fi Access Point mode, ready to be connected to the Samsung SmartThings app. AP is a mode indicator, not a fault. The dishwasher is broadcasting its own temporary Wi-Fi network so a phone can connect directly during setup.
