LG Dishwasher Error Codes

Updated February 21, 2017

An LG dishwasher equipped with a digital display panel shows error codes to assist in the diagnosis of problems that arise during normal use. These error codes are interpreted and used to determine what types of repairs are needed. If an error code is displayed, record it and make the needed repairs or contact a service technician.

IE

The "IE" error code indicates a problem with the water inlet. The water supply valves are not turned on fully or the inlet hoses are kinked, clogged or frozen. Remove kinks in the hoses and remove clogs with a straightened coat hanger. If this does not resolve the problem, contact a service technician.

OE

A drainage problem causes "OE" to be displayed on the digital display panel. The drain hose is likely kinked, clogged or frozen. Inspect the hose and remove kinks. Unclog the hose, if needed. Replace the hose if the problem is not resolved. If the dishwasher still does not drain, contact a service technician to inspect the dishwasher and determine the problem.

FE and E1

"FE" is displayed if the dishwasher is supplied an excessive amount of water. The "E1" error code means the dishwasher has developed a leak. Turn off the water supply valves and contact a service technician to repair the dishwasher.

HE

The heater circuit has failed if "HE" is displayed. Discontinue use and contact a service technician. The dishwasher requires servicing.

TE

"TE" means the thermistor has failed or the temperature of the water entering the dishwasher is over 90 degrees Celsius. Turn the temperature down on the hot water heater in the home. If the error code reappears, replace the thermistor.

PF

The dishwasher displays "PF" to indicate there has been a power failure. This is not an error code. The dishwasher automatically restarts 10 seconds after the code displays.
