Risk level

Professional inspection is recommended.

Urgency

High

Quick answer

With i30, the Electrolux anti-flood system has detected water in the dishwasher base and the drain pump may keep running. Close the inlet tap first, unplug the appliance, and do not tilt it or open the base.

Safety first

Stop and check this first

  • Water under the dishwasher and mains power: cut the power before drying the floor and do not open or tilt the base. Electrolux says to turn off the water to avoid flooding.

Safe checks you can perform

  • Cut water and power
  • Load, foam, filters and door seal
  • Test after a night to dry

Leave these tasks to a qualified professional

  • Do not attempt this professional task: Find the leak in the base
  • Do not attempt this professional task: Leak free test after the repair

What a technician must be able to justify

A technician is coming

These are the steps they must carry out and show you. Tick them as they work: if steps are skipped, do not accept a part swap.

These are not instructions for opening or handling the equipment yourself. They are the checks that should support a technical conclusion.

  1. Find the leak in the base

    What they doWith the appliance disconnected and no water, the technician opens the base, removes the water and looks for the leak point.

    They must show youthe leak area and affected part, with a photo.

    In writingthe leak origin, the replaced part and its reference.

  2. Leak free test after the repair

    What they doAfter the repair, the technician runs a full programme and checks the base stays dry and i30 does not appear.

    They must show youa dry base at the end of the programme.

    In writingthe test and its result.

Before accepting a part or repair

Nothing has been shown yet. Do not accept a part swap based on the code alone.

Checks and evidence, step by step

Follow the documented order. An error code identifies the affected system, but it does not prove by itself which part has failed.

  1. 1

    Cut water and power

    No special tools

    Procedure

    Who:
    you.
    How:
    close the dishwasher inlet tap and unplug it or switch off its circuit; do not tilt it or remove the kickplate.
    Result that matters:
    no incoming water and no power.
    If there is water on the floor:
    do not step in it with the appliance plugged in; dry it after cutting power and book a repair.
    If no water is visible:
    move on to the load and filters.
    Evidence to keep:
    a photo of the code and the floor.

    Evidence: Dishwasher displays error code i30

  2. 2

    Load, foam, filters and door seal

    No special tools

    Procedure

    Who:
    you.
    How:
    with the appliance unplugged, look for foam, large items stopping the arms, dirty filters, arms or sump, and a dirty or damaged door seal. Also check the appliance is level.
    Result that matters:
    none of these causes visible.
    If there was foam or something blocking:
    correct it and go to the drying test.
    If the seal is damaged:
    book a repair; do not use it like that.
    Evidence to keep:
    photos of the load, filters and seal.

    Evidence: Dishwasher displays error code i30

  3. 3

    Test after a night to dry

    No special tools

    Procedure

    Who:
    you.
    How:
    leave the dishwasher unplugged overnight with the tap closed; next day plug in, open the water and run a programme.
    Result that matters:
    whether the programme finishes without i30.
    If it finishes:
    foam or loading was the likely cause.
    If i30 returns:
    close the tap, unplug and call a technician; there is an internal leak.
    Evidence to keep:
    the test date and result.

What it means

Electrolux links i30 to water where it should not be: it collects in the base and triggers the anti-flood device, which is why the drain pump may run constantly. Electrolux gives three origins: over foaming, a blocked spray arm or a large item deflecting the jet onto the door, and an internal leak. Leaving it off overnight with the tap closed may clear the code, but if the leak is still there, i30 comes back. The code does not say where the water comes from.

Warnings and stop conditions

Symptoms and causes

Probable causes · in order

  • Over foamingPossible

    Too much or the wrong detergent fills the tub with foam. You see foam when you open it; Electrolux says to switch off at the mains and leave it overnight to disperse.

    Evidence: Dishwasher displays error code i30

  • Blocked spray arm or deflected jetPossible

    A tray or large item stops an arm turning or sends water into a corner or onto the door, stressing the seal. You see it in the load.

    Evidence: Dishwasher displays error code i30

  • Internal leak into the baseCommon

    If the code returns with a correct load, no foam and a night to dry, the water comes from inside. Electrolux says an authorised technician is needed.
