27 error codes

CodeMeaning
AE stands for Aqua Error. It signals that the anti-flood float switch located in the drip pan at the bottom of the dishwasher has detected accumulated water and triggered an automatic shutdown to prevent further water damage to surrounding cabinetry and flooring.
highintermediate
1EThe pressure sensor that monitors water level in the tub is sending a signal the control board doesn't recognize. Either the tube feeding it is blocked, the sensor diaphragm has failed, or there's a wiring issue between the sensor and the main board.
moderateintermediate
6EThe dishwasher's optical soil sensor can't get a clean reading. Either the infrared beam is blocked by grease or mineral scale on the lens, the wiring connector has come loose, or the sensor's internal LED has actually burned out and the board's not getting any signal at all.
moderateintermediate
AEAE means the leak detection float switch in the base pan has been triggered by standing water. The control board cuts the wash cycle, fires up the drain pump, and won't let the machine run again until that tray is bone dry and the float drops back down.
highintermediate
AEThe base pan leak sensor has detected water or elevated moisture in the drip tray beneath the dishwasher tub
criticalbeginner
BEA button on the control panel is stuck in the pressed position or the control panel PCB is registering a continuous key-down signal
moderateintermediate
BEEPINGThe dishwasher's interrupting its cycle because it's detected a fault. That's usually a door latch that's lost electrical contact, a leak sensor in the base pan that's gotten wet, or a drain that can't clear water fast enough. The beeping is the machine's way of saying it won't keep running until you address that.
moderateeasy
CLCL stands for Child Lock. When it's showing, the dishwasher's control board has disabled all button inputs on the panel. Nothing will respond until you send the unlock command. It's a software state stored in the main PCB, not a hardware fault.
lowbeginner
CLChild lock is active. The control panel is locked and will not respond to button presses until unlocked.
lowbeginner
E1The NTC thermistor is reading outside its expected resistance range, and the control board's flagging a temperature circuit fault. Basically the sensor's sending back an impossible number, so the board shuts everything down rather than risk scalding the pump or under-heating the wash.
highintermediate
HEThe control board watches how fast water temperature climbs during the cycle. If it doesn't see the water hit target temp within its allowed window, it throws HE and shuts the cycle down. Could be the thermistor feeding it bad data, the element not firing at all, or the wiring in between failing under load.

IEThe water level sensor did not detect enough water in the tub after the fill valve was commanded to open during the fill cycle
moderatebeginner
L2The secondary leak sensor, positioned further back in the base pan than the primary AE sensor, detected moisture. The control board locks everything down immediately to keep water off your floor.
criticalbeginner
LEThe direct-drive inverter wash motor has stalled, locked, or failed to reach operating speed within the expected startup window

LEAKINGWater's escaping somewhere it shouldn't during the wash cycle. LG's QuadWash system runs at higher pressure than most brands, so even a small gap in the door gasket or a cracked spray arm can push water out pretty aggressively. The machine itself doesn't always know it's leaking unless there's a float sensor triggered in the base pan.
moderateintermediate
NEThe control board tried to read the NFC tag module during startup or mid-cycle and got no response back. It's a communication timeout, not a hardware failure in most cases.
lowbeginner
NOISEThe dishwasher is producing an unusual sound outside its normal operating hum. Could be mechanical debris caught in the pump impeller, failing motor bearings, a spray arm hitting something, or the self-cleaning filter running its cycle. LG's Direct Drive motor has a normal low hum, so grinding, squealing, or rhythmic thumping is outside spec.
moderateintermediate
NOT-CLEANINGYour LG dishwasher isn't getting enough water pressure to the spray arms, isn't heating water properly, or can't circulate water because of a clog somewhere in the system. The wash pump pulls water from the sump, the spray arms spin and spray it at your dishes, and anything blocking that flow means dirty dishes at the end.
moderateintermediate
NOT-DRAININGThe dishwasher's drain pump isn't clearing water from the sump at the end of the cycle. Could be a blocked filter stopping flow before it even reaches the pump, a foreign object jamming the impeller, a failed pump motor, or something downstream like a kinked hose or a plugged garbage disposal connection.
moderateintermediate
NOT-DRYINGYour LG dishwasher finished the cycle but dishes are still wet. Usually means the condensation drying process broke down somewhere, whether that's no rinse aid, a dead vent fan, a failed heating element, or just plastic items that physically can't dry this way.
moderateintermediate
OEThe drain cycle timed out. Water wasn't removed from the tub within the expected window, so the board flagged it and shut everything down.
moderatebeginner
P1The wash pump circuit detected a pressure or performance fault. The pump's running but it's not building the spray pressure the board expects, or the pump motor circuit has started to fail outright.
highadvanced
REThe control board detected a fault in the rinse aid dispenser circuit or the rinse phase didn't complete right. Either the solenoid didn't fire when it was supposed to, or the board's feedback loop confirmed the dispenser door never actually opened during the cycle.
moderatebeginner
SMELLSBacteria feeding on trapped food and grease inside the filter, sump, drain hose, or door gasket produce hydrogen sulfide gas. That's your rotten egg or sewer smell. It builds up over time from missed cleanings and too many low-temperature wash cycles that never get hot enough to actually kill anything living in there.
moderateintermediate
UNRESPONSIVEThe dishwasher's control board is basically stuck. It's not responding to button presses because it's either frozen mid-cycle, caught in an error loop, or has a sensor screaming at it to stop. A reset clears the board's short-term memory and tells it to start fresh.
moderateeasy
WONT-STARTThe control board isn't receiving the start signal it needs. Either the door switch hasn't confirmed the door is closed, a safety lockout's active, the board lost power from a blown fuse, or the board got confused after a power event. The machine won't run any cycle until those conditions clear.
