Dishwasher
CE
The CE error code on an LG dishwasher indicates a communication error — typically between the main control board and the motor or other components. It’s a moderately serious fault that often stops the cycle completely, but in many cases it can be resolved without calling an engineer.
What does this error mean?
CE stands for ‘Communication Error’. Your LG dishwasher’s main PCB (printed circuit board) is failing to send or receive signals correctly from one or more components — most commonly the wash motor or the control panel. This is the appliance’s way of saying that its internal ‘conversation’ between parts has broken down, which prevents it from running safely.

🔍 Likely causes
🛠️ Step-by-step fix
Perform a hard reset: switch off the dishwasher at the wall socket, leave it unplugged for 5–10 minutes, then plug back in and restart a cycle. This clears temporary glitches caused by power surges.
Check your home’s consumer unit (fuse box) to confirm the circuit breaker for the kitchen hasn’t tripped. Reset it if needed before retrying the dishwasher.
Open the door and inspect the door latch for visible damage or misalignment. A door that doesn’t click shut firmly can trigger communication faults — realign or replace the latch if worn.
Pull the dishwasher out slightly and inspect the wiring harness at the back for any visible damage, kinks, or loose connectors. Re-seat any connectors that appear loose — do not open any sealed electrical components.
Check the inside of the dishwasher for standing water, which may indicate a drainage issue affecting the motor’s operation. Clear any blockages in the filter and drain hose.
If the CE code persists after all the above steps, stop here — the fault is likely the main PCB or wash motor, both of which require a professional repair.
📞 When to call a professional
If the CE error returns after a hard reset and your checks of the door latch, wiring, and drainage have found nothing obvious, call an appliance repair engineer. Tell them it’s an LG dishwasher showing a CE (communication error) code, and mention whether you noticed any unusual noises before the fault appeared — this helps them diagnose whether the issue is the PCB or the wash motor. Do not attempt to open the control panel or disconnect internal wiring yourself.
⚖️ Repair or replace?
A professional repair for a CE error typically costs £80–£160 depending on whether the fault is the wiring (cheaper) or the main PCB or motor (more expensive). If your LG dishwasher is under 5 years old, repair is almost always worth it. If it’s 8 years or older and the PCB or motor needs replacing, a new mid-range dishwasher (£350–£550) is often better value than a £150+ repair bill.
