What the display tells you
What does LG IE mean?
LG's dishwasher support guide says IE appears when the dishwasher does not receive a specified amount of water. The guide lists an interrupted supply, a closed valve, or a compressed supply hose among possible causes.
This is the condition described by the maker—not a remote diagnosis of your appliance. A code can point to a system or symptom without confirming which part, if any, needs replacement.
Safe first checks
Begin with what you can see and with instructions for the exact model. Do not skip the maker's cautions to clear the display faster.
- Confirm the display reads IE—not a similar-looking code—and note the dishwasher's model number.
- Check that the kitchen tap is supplying water and that a safely visible supply valve is open.
- Look for a visibly pinched supply hose without pulling the dishwasher from its cabinet. For anything that requires disconnection or access behind the appliance, use the model manual or arrange service.
When to stop and get help
Stop if water is leaking, the hose or valve is hidden behind the installed dishwasher, or the code persists after the visible supply is checked. Do not pull out the appliance to investigate.
Why the model number matters
LG's guide is for its dishwasher line and notes that procedures can differ by model. Use the full model identifier to open the matching manual before further checks.
Look for the full model identifier in the owner's paperwork or on a label that is safely visible without moving, tipping, or opening the appliance. Use that identifier when you open the manufacturer source below.
