IE Error Code on LG Dishwasher: Causes & Fixes

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

1. Check Water Supply
   • Ensure the water tap is fully open.
   • Inspect the inlet hose for kinks or clogs.
   • Clean the inlet filter screen.
2. Test the Inlet Valve
   • Replace the water inlet valve if it’s defective.
3. 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.
