What does the AEG i30 error code mean?

i30 means the anti-flood float switch inside the base tray of the AEG dishwasher has been raised by accumulated water. This is a safety shutdown and the machine will not operate until the base tray is emptied and the float drops back to its rest position.

🔍 Symptoms

  1. Machine completely locked — no programmes will start
  2. Drain pump may be running continuously
  3. Possible water visible under or around the machine
  4. All panel lights flashing or i30 displayed
  5. Machine was working and suddenly stopped mid-cycle

How to fix the AEG i30 error code

  1. Unplug the machine immediately.
  2. Tilt the machine 45 degrees forward to drain the base tray.
  3. Allow to dry thoroughly (24+ hours).
  4. Reconnect power — if i30 clears, run a test cycle while watching closely.
  5. Find and repair the leak source before regular use. The door seal and internal hose connections are the most common AEG leak points.

Frequently Asked Questions (FAQ)

Q: How do I know if the float switch itself is faulty on my AEG dishwasher?

A: Once the base tray is empty and the machine is upright, if i30 persists, the float switch may be stuck in the raised position. Visually inspect it — the float should sit low in the tray when no water is present.

Q: Can I prevent i30 on my AEG dishwasher?

A: Regular inspection of the door seal and internal hose connections can catch leaks before they become a flood protection event. Replace the door seal every 5–7 years as preventive maintenance.

Q: I had i30 last month and now it has happened again — what is leaking?

A: A recurring i30 confirms an active, ongoing leak. The most likely culprits are a perished door gasket or a split internal hose. A systematic visual inspection during a wash cycle (looking underneath with a torch) should locate the source.
