If your LG dishwasher displays the IE error code, it usually indicates a water inlet problem—meaning the dishwasher isn’t filling with water properly.
However, if your dishwasher does receive water but still shows the IE error after about 3 minutes, the issue could point to a circulation pump motor error.
Why Does the IE Error Code on LG Dishwasher Appear?
- Water Supply Issue:
- Low water pressure.
- Blocked or kinked inlet hose.
- Faulty inlet valve.
- Pump Motor Issue (if water fills correctly):
- Once water enters the dishwasher, the load on the pump impeller decreases.
- This reduces the motor’s amperage.
- The dishwasher’s control board uses this motor feedback to confirm water presence.
- If the signal isn’t correct, it triggers the IE error code even though water is present.
How to Fix LG Dishwasher IE Error Code
- Check Water Supply
- Ensure the water tap is fully open.
- Inspect the inlet hose for kinks or clogs.
- Clean the inlet filter screen.
- Test the Inlet Valve
- Replace the water inlet valve if it’s defective.
- Check the Circulation Pump Motor
- If water fills correctly but the error persists, the pump motor may need testing or replacement.
Final Thoughts
The LG dishwasher IE error code usually means a water supply issue, but if water fills normally, it may signal a pump motor problem. Start by checking water flow, then move on to motor diagnostics.
