Electrolux Dishwasher i20 Error Code

Electrolux says i20 means the dishwasher is not draining properly and directs owners to check the disposer connection, visible drain hose, installation height, and user-accessible filter or glass trap before service.

Applies to Electrolux dishwasher

What the appliance detected

Detected condition

The dishwasher did not drain completely or is not draining properly.

What may contribute

Possible causes

  • A disposer knockout plug may still be installed where the dishwasher drains through a newly installed disposer.
  • The visible drain hose may be blocked, pinched, restricted, or routed below the documented minimum height.
  • Food soil may be restricting the user-accessible glass trap or filter.
  • An internal drain pump, hose, sensor, wiring, or control problem may remain after external checks.

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 exact display and model

    • Photograph the code or message before clearing it so the original display is preserved.
    • Confirm the complete model number and compare it with the Electrolux owner manual before using any model-specific procedure.

  2. Use only documented owner-accessible checks

    • If the dishwasher drains through a disposer, confirm the installer removed the dishwasher knockout plug.
    • Inspect only the safely accessible drain hose for obvious pinching, crushing, or restriction without pulling out a hardwired dishwasher.
    • Compare the drain-hose routing and height with the exact installation instructions; Electrolux currently specifies a minimum 32-inch height in its i20 support article.
    • Clean the glass trap or filter only if the exact model manual identifies it as owner-accessible.
    • If the external issue is corrected, use the Electrolux-documented Cancel control or a single safe power interruption only as the exact model instructions allow.

  3. Stop before internal diagnosis

    • If the condition returns after the documented external checks, request Electrolux support or qualified service.
    • Do not remove service panels, bypass the door latch, probe live voltage, or access pumps, heaters, wiring, controls, or other internal components.

Actions not recommended

  • Do not reach into wet areas while electrical power is connected.
  • Do not repeatedly reset a breaker that trips again or use a reset to conceal a recurring fault.
  • Do not replace a pump, heater, latch, control, sensor, or wiring part from the display alone.

When to stop and request service

  • i20 returns after the accessible drain path and filter checks are normal.
  • Standing water cannot be addressed without internal access.
  • The breaker trips again, a leak is present, or pump, wiring, sensor, or control diagnosis would be required.
