LG Washing machine shows IE error code?

An IE error code will appear if the washer has not filled with water in approximately 8 minutes.

Are the water valves opened completely?

If an IE error code appears on the washer, check to make sure both hot and cold-water taps are open completely. After both valves have been opened, unplug the washer for 10 seconds and retry the wash cycle.

Are the inlet hose filters clogged?

There are filters on the inlet hose connections of the washing machine. They are intended to filter away mineral deposits from hard water and other debris from getting into the unit. If clogged, water will not flow through these filters into the washer. Turn off both the hot and cold water taps, disconnect the inlet hoses from the back of the washing machine, and clean the inlet filters gently but thoroughly.

Are the inlet hoses attached properly?

If the inlet hoses are not attached to the machine correctly, it will prevent proper water flow to the washer. Turn off the hot and cold water supply then disconnect and reconnect the inlet hoses. Ensure that they are threaded properly. After the hoses have been reconnected, open the water taps completely, check for leaks, and unplug the washer for 10 seconds and retry the wash cycle.

NOTE: The inlet filters are inside the hose connections on the back of the washer. Because of their small size, take care when removing and cleaning the inlet filters so that they do not break.
