What does it mean when the light on my LG dishwasher is blinking?

When the light on your LG dishwasher is blinking, it indicates a status, error, or attention condition rather than normal operation, and the meaning depends on which light is blinking. If the Start light blinks, it usually means the door was opened mid-cycle or the cycle was paused and needs to be resumed by closing the door firmly and pressing Start again. If the display shows blinking error codes, common ones are: OE blinking means drain error, filter, drain hose, or pump is clogged; IE blinking means inlet error, water supply is off or inlet valve filter is blocked; LE blinking means motor error or leak detected in base pan; AE blinking means leak error with water in base; HE blinking means heater error; tE blinking means temperature sensor error; FE blinking means overfill due to faulty water inlet valve. If the child lock or control lock light blinks, it means the lock is active and buttons are disabled, hold Child Lock for 3 seconds to deactivate. If all lights blink after a power outage, perform a hard reset by turning off the breaker for 10 minutes. Blinking often indicates the dishwasher needs filter cleaning, which should be done monthly by removing the lower rack and twisting out the cylindrical filter assembly to rinse under water. Check your manual for your specific model code.
