Dishwasher
CE
The CE error code on a Samsung dishwasher indicates a communication error between the main control board and the motor or other internal components — it’s a moderately serious fault that usually requires investigation beyond a simple reset.
What does this error mean?
CE stands for Communication Error. Your dishwasher’s main PCB (printed circuit board) has lost reliable communication with one or more internal components, most commonly the wash motor or drain motor. The appliance stops as a safety measure because it can’t confirm the hardware is responding correctly.

🔍 Likely causes
🛠️ Step-by-step fix
Reset the dishwasher: switch it off at the wall socket, wait 5 full minutes, then switch back on and run a short cycle. A temporary communication glitch can clear with a hard reset.
Check your home’s fuse box: a partial power trip or blown fuse can cause voltage irregularities that trigger a CE fault. Reset any tripped breakers and try again.
Inspect the door latch: open and firmly close the door, ensuring it clicks securely. A misaligned or worn latch can confuse the control board and generate a communication error.
Pull the dishwasher out slightly and inspect the external wiring at the back — look for any visibly pinched, burnt, or disconnected cables. Do NOT open the main body or touch internal wiring; stop here if you find damage and call an engineer.
Check for standing water in the base of the machine by removing the bottom rack and filter cover. Water pooling near the motor can cause the CE code — clean the filter and sump area thoroughly if dirty or blocked.
If none of the above resolves the fault, the issue is most likely an internal wiring connector, the wash motor, or the PCB — all of which require a qualified appliance engineer to diagnose and repair safely.
📞 When to call a professional
Call an appliance engineer if the CE code returns after a hard reset, if you spot burnt wiring or smell burning, or if the motor makes unusual noises before the error appears. When booking, tell the engineer you have a Samsung dishwasher showing a CE (communication error) code — this helps them bring the right diagnostic tools and likely spare parts.
⚖️ Repair or replace?
A professional repair for a CE error typically costs £80–£180 depending on whether it’s a wiring fix, motor replacement, or new PCB — PCB replacements sit at the higher end. If your Samsung dishwasher is under 5 years old, repair is almost always worth it; over 8 years old with a PCB or motor fault, replacing the appliance is often more economical given new models start from around £350.
