CE
LG Dishwasher
Severity: CriticalWhat Does This Error Mean?
The CE error means your LG dishwasher detected an abnormal motor current. The wash motor is drawing too much or too little electrical current. This is a critical error — the machine stops to prevent motor damage. A blocked spray arm, foreign object in the pump, or a failing motor are common causes.
Affected Models
- LDF5545ST
- LDT5678SS
- LDFN4542S
- LDT7808SS
- Most LG dishwasher models
Common Causes
- Foreign object (broken glass, bone fragment) lodged in the pump impeller
- Blocked or jammed spray arm that is restricting water circulation
- Motor bearing failure causing the motor to draw excessive current
- Wiring harness to the motor is loose, corroded, or damaged
- Control board malfunction sending incorrect power to the motor
How to Fix It
-
Cancel the cycle and unplug the dishwasher from the wall.
Safety first. Never reach into the dishwasher with it powered on. Wait for the machine to fully stop before opening.
-
Remove the bottom rack and check the spray arms.
Spin both the lower and upper spray arms by hand. They should spin freely. If one is stiff or stuck, remove it and clean the holes with a toothpick.
-
Remove the filter and inspect the pump area for obstructions.
Twist out the cylindrical filter at the bottom of the tub. Look for broken glass, food debris, or small objects that could be jamming the pump impeller.
-
Clean the filter and rinse it under running water.
A clogged filter makes the motor work harder, increasing current draw. Clean the filter every 1–2 months to prevent this.
-
Plug the dishwasher back in and run a short cycle to test.
If the CE error returns immediately, the motor or control board needs professional inspection. Do not keep trying to run the machine.
When to Call a Professional
If clearing the pump and spray arms doesn't fix the CE error, call a technician. Motor and control board repairs require professional diagnosis. LG support or a licensed appliance technician can safely inspect and repair the motor. Expect repair costs of $150–$400 depending on whether the motor needs replacing.
Frequently Asked Questions
What is the pump impeller in a dishwasher?
The impeller is a small spinning blade inside the pump. It circulates water through the spray arms during a wash cycle. If a piece of broken glass or food debris jams the impeller, it can't spin. The motor then draws too much current trying to force it, which triggers the CE error.
How often should I clean the dishwasher filter?
Once a month is a good habit if you run the dishwasher frequently. A dirty filter is one of the most common causes of motor and drain problems. Cleaning it takes about 2 minutes and can prevent costly repairs.
Can the CE error damage my dishwasher if I ignore it?
Yes — running the motor under abnormal current loads can burn it out. A burned motor is one of the most expensive dishwasher repairs. Always stop the machine and investigate the cause of the CE error promptly.
