LG Dishwasher IE Error Code

IE points to a fill condition, not proof that a valve has failed. Start with the water supply, visible hose condition, installation height context, and service boundaries.

Applies to LG dishwasher

What the appliance detected

Detected condition

LG says IE appears when the dishwasher does not receive the specified amount of water.

What may contribute

Possible causes

  • The water supply valve is closed or water is cut off.
  • The water supply hose is kinked, pinched, bent, or frozen.
  • The inlet valve filter may be clogged.
  • Water pressure may be too low for the dishwasher.

Start conservatively

Safe preliminary checks

Work in order and stop whenever a step is not supported by the documentation for your model.

  1. Record the code and model

    • Photograph or write down IE before clearing the display.
    • Confirm the full model number and owner manual before using model-specific instructions.

  2. Check the accessible water supply

    • Make sure the dishwasher water supply valve is open and household water service is available.
    • Visually check the accessible supply hose for kinks, pinching, bending, or freezing without disconnecting plumbing.

  3. Stop at plumbing and internal-service boundaries

    • If water pressure, an inlet screen, or a valve may be involved, use a qualified plumber or appliance technician.
    • Stop immediately for leaking water, electrical warning signs, or any step that would require opening panels or live electrical access.

Actions not recommended

  • Do not remove panels, test live voltage, replace an inlet valve, or disassemble internal water components based on IE alone.
  • Do not work on plumbing connections if water cannot be shut off safely.
  • Do not continue running cycles if water is leaking near electrical parts or flooring.

When to stop and request service

  • Request service if IE returns after confirming the accessible water supply and hose condition.
  • Use a qualified plumber for low water pressure, frozen plumbing, or supply-line work.
  • Stop and request qualified help for leaks, electrical warning signs, or any required internal access.
