Electrolux Dishwasher i40 Error Code

Electrolux says i40 can occur when food soil builds up in the sump and recommends cleaning the glass trap and filter before rerunning the dishwasher.

Applies to Electrolux dishwasher

What the appliance detected

Detected condition

The dishwasher reports a clogged filter or sump condition.

What may contribute

Possible causes

  • Food soil may have accumulated in the owner-accessible filter or glass-trap area.
  • The visible filter may not be seated or maintained as the model instructions require.
  • A persistent condition may involve an internal water-level, drain, pump, sensor, wiring, or control issue that the code alone cannot identify.

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

    • Turn the dishwasher off and follow the exact model manual before touching a wet filter area.
    • Remove and clean only the glass trap or filter that Electrolux identifies as user-accessible for the model.
    • Reinstall the accessible filter components exactly as documented and run one normal test cycle.

  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

  • i40 returns after the user-accessible filter or glass trap is clean and correctly installed.
  • The sump area cannot be reached using an owner-manual procedure.
  • An internal pump, sensor, wiring, or control check would be necessary.
