Direct answer
On a supported LG dishwasher, IE means the water level remained too low during fill. Open the supply valve and straighten the inlet hose. Then check for frozen plumbing, low household pressure and a clogged inlet screen using model instructions.
What this covers
- LG dishwashers displaying IE
- The code and product type exactly match the official source
- Customer-accessible checks before component replacement
What it does not cover
- ×A similar code on another manufacturer or appliance type
- ×Codes omitted from the exact model manual
- ×Internal wiring, sealed-panel or live-electrical repair
Confirm IE on the exact model
ReversiblePhotograph the complete display, record the model tag and note the cycle stage. Similar-looking codes can mean different things on another product line.
Check the condition named by the code
ReversibleOpen the supply valve and straighten the inlet hose.
Correct the remaining user-serviceable cause
ReversibleCheck for frozen plumbing, low household pressure and a clogged inlet screen using model instructions.
Run one controlled verification
ReversibleRun a cycle and confirm a normal fill after the initial drain. Service is needed if supply is adequate but the inlet valve does not operate.
