What Does Error i30 Mean?

The AEG dishwasher i30 error indicates a water leakage detection issue, triggered by the internal flood safety system. This typically occurs when water is detected in the base or undercarriage, leading to continuous beeping and flashing lights. The dishwasher may stop running or continuously pump water. Common causes include actual leaks, over-foaming, or obstructions preventing proper spray arm function. To resolve, check for visible water, ensure proper loading, and use the correct detergent. If the issue persists, consider professional assistance.

Common Symptoms:

  • Dishwasher shuts off or will not run a cycle when i30 appears (may pump continuously).
  • Continuous or repeated draining and/or beeps with the error. [AEG Support](
  • Visible water or moisture in the base area when pulled out.

Possible Causes

  • Water in the base/undercarriage triggering the anti‑flood/flood sensor (high)
  • Over‑foaming (excess suds) causing water to collect where the sensor trips (medium)
  • Obstruction/incorrect loading causing spray arms to deflect water and wet areas that trigger leak sensors (medium)

How to Fix Error i30

DIY Fix Initial safety and check for water in base

  1. Immediately stop dishwasher and turn off water supply and power (unplug or breaker). [AEG Support](
  2. Pull the dishwasher slightly out and check for visible moisture or water in the base area.
  3. If water is present, absorb/collect water with towels and allow base to dry thoroughly with door open 24–48 hrs. [AEG Support](

DIY Fix Basic user‑level checks and cleaning

  1. Check and clean filters and spray arms for blockages.
  2. Ensure loading does not block spray arm rotation and avoid large items that can cause uneven water splash.
  3. Use correct dishwasher detergent and avoid hand dish soap to prevent excessive foaming.

Technician Only Inspect for internal leaks and component faults

  1. Remove decorative panels and access base/undercarriage with the appliance unplugged.
  2. Inspect hoses, seals, door gasket, sump, pump area for cracks, loose clamps, or defective seals.
  3. Check flood/float sensor and pressure switch or duct for clogging or malfunction (clean or replace as needed).

Parts needed: Door seal, Drain and inlet hoses, Pump gasket, Flood/float sensor

🛑 When to Call a Pro:
  • After basic drying and checks, if i30 persists repeatedly. [AEG Support](
  • If internal leak source cannot be found or water continues entering base.
