LG Dishwasher Error Code 00:E2

The 00:E2 code on an LG dishwasher indicates a steam generator error caused by the water leveling sensor operating abnormally. The control board monitors this sensor to confirm a safe water level inside the steam chamber before activating heating. When the sensor signal falls outside expected parameters, the dishwasher triggers this fault and suspends steam operation to prevent damage or unsafe conditions.

The dishwasher will disable steam generation when the 00:E2 fault is active, which limits the risk of operating the steam heater without confirmed water levels. Standard wash cycles may still function depending on how the dishwasher handles the fault, but running the appliance repeatedly without addressing the underlying cause is not recommended. Have the sensor and wiring inspected before continuing regular use.

Repair costs vary depending on the root cause. If the issue is simply a loose wiring connection, there may be little to no parts cost involved. Replacing the water level sensor typically falls in the range of $20 to $80 for the part, plus labor if a technician is hired. If the full steam generator assembly requires replacement, total repair costs including parts and labor can range from $150 to $400 or more depending on your location and service rates.

Start by checking all wiring connections between the water level sensor and the control board, as loose or corroded connectors are a common cause. If the connections are secure, the water level sensor should be tested for proper continuity and resistance. If the sensor tests bad, it will need to be replaced. In some cases the steam generator assembly itself may need replacement if the sensor and wiring are both confirmed to be in good condition.

A power reset may temporarily clear the error code, but if the water level sensor or its wiring has an underlying fault, the code will return once the dishwasher attempts to use the steam generator again. Resetting is useful as a first step to rule out a temporary glitch, but a persistent 00:E2 code requires proper diagnosis and repair of the sensor circuit.
