LG Dishwasher IE Error Code: Water Inlet Supply Fix
Quick Answer: The IE (Inlet Error) code on an LG dishwasher means the unit did not detect adequate water entering the tub within the specified fill period. It is caused by closed water valves under the sink or a clogged inlet filter screen.
⚠️ Check the Water Supply Line First: Unlike washing machines, dishwasher inlet valves rarely burn out—90% of LG dishwasher IE errors happen because someone partially closed the under-sink angle stop valve while doing plumbing work.
