The LE error code on a LG dishwasher indicates a problem with the water inlet. This can be caused by a number of things, such as a clogged water inlet filter, a kinked water supply hose, or a failed water inlet valve. If the water inlet filter is clogged, it will need to be replaced. If the water supply hose is kinked, it will need to be replaced. If the water inlet valve is failed, it will need to be replaced.
