What are The Most Common Error Codes?

If you see a blinking light on your dishwasher, there is a probability of an Error Code. Read below to learn how to fix certain problems with the appliance.

IE Error Code

An IE error code on an LG dishwasher indicates that it isn’t filled with water. Naturally, this implies that your dishes will not be washed. However, there are a few basic methods for testing your water connection.

The first step is to check your water supply is separated from the valve to ensure it is completely open. Also, inspect your water intake supply hose for kinks. In addition, examine the filter screen on the water entry valve for any obstructions. If you detect any clogs, remove them and your LG dishwasher should be fully working again.

Error Code nE

This error code means a diverter motor failure. You need to inspect the wire harness connections on the diverter motor and position switch.

To do so, unplug the LG dishwasher’s power supply. All disconnected wires should be rejoined. If they are not loose, disconnect them and determine the motor’s resistance by using a multimeter. If there is an infinite resistance, you have to change the diverter motor.

HE Error Code

When you notice this error number, it signifies that your dishwasher’s thermistor or temperature gauge detects that the water in it is not heating or is heating above the recommended temperature.

If the dishwasher’s temperature sensor indicates a higher temperature than is typical for an effective LG dishwasher functioning, you may need to switch out the electronic control board. This is due to a blocked heater relay on the control board, which keeps the heating element turned on at all times.

Error Code OE

An OE error code indicates there is a clog in the sink drain or waste disposal. Nevertheless, when you examine both of the elements, and they operate as usual, then inspect the dishwashing hose.

Unplug it from the sink of the garbage disposal connector and inspect for grease clogs. The LG dishwasher may have an air gap, which is why you should make sure to clear any blockages. Don’t forget to switch the dishwasher off the power source. Also, check the sump and drain pumps for dirty elements.

E1 or AE Error Code

A low tub water level or an excessive circulation pump speed might trigger an LG dishwasher error E1 or AE. It may also get some water into the bottom of the appliance cabinet, causing the flood switch.

Disconnect the dishwasher and turn off the water supply. The liquid may leak from the fill line, drain pump, hose, door seals, or sump. As a result, call the professional who can fix dishwasher.

Error Code LE

The LE error appears when the pump impeller is clogged and unable to spin. Disconnect the dishwasher, check for clogs, and clear the sump from any foreign objects and dirt.

In order to ensure the sump is clean, examine the pump’s wiring connections and reconnect any unplugged ones. If you haven’t found the issue, call the plumber or technical expert, who will examine the resistance of the appliance using a multimeter.

Error code FE

This error code means that your dishwasher’s drain pump will operate automatically. A leaking water inlet valve or a blocked sensor on the electronic control panel may cause your dishwasher to fill continuously.

You should disconnect the dishwasher and observe whether it remains filled with water. If this happens, you should replace the water inlet valve.

tE Error Code

The tE error indicates that the thermistor is possibly malfunctioning. Check the component for the ohms and temperature within an acceptable range. If the measures are lower than the standard ones, change the thermistor.


If your LG dishwasher displays error codes or visibly malfunctions, attempt to examine the issue properly. Some of these can be readily resolved with basic troubleshooting, restarting the dishwasher, or a simple replacement of a component.

However, some failures are better left to qualified repair technicians, particularly when safety is a concern. Contact your appliance repair professionals to provide the LG dishwasher diagnostic mode, and fix it swiftly and under warranty.
