What Does Error IE Mean?

The LG Dishwasher IE error indicates a water inlet issue, preventing the unit from filling with water within the expected time. This can occur during the water fill phase, resulting in a blinking display. Common causes include a closed or partially open water supply valve, kinks or blockages in the water inlet hose, and low household water pressure. Cleaning the inlet filter and checking the water supply are essential first steps for resolution.

Common Symptoms:

  • Dishwasher displays IE error before or during water fill phase
  • Dishwasher does not fill with water or fills very slowly
  • Cycle may not start due to insufficient water

Possible Causes

  • Water supply valve closed or not fully open (high)
  • Kinked, pinched, bent, or blocked water inlet hose (high)
  • Low household water pressure (medium)
  • Faulty water inlet valve (medium)
