The LG dishwasher error code IE means that there is a problem with the water inlet. This can be caused by a clogged water inlet filter, a kinked or damaged water hose, or a problem with the water valve. If the water inlet filter is clogged, it will need to be replaced. If the water hose is kinked or damaged, it will need to be replaced. If the water valve is not working properly, it will need to be replaced.
