What does the Zanussi i30 error code mean?
i30 means the anti-flood float switch has been lifted by water that has leaked into the base tray. The machine shuts down to prevent water damage. This is a safety response — the underlying cause is a leak that must be found and fixed.

Frequently Asked Questions (FAQ)
Q: How do I stop my Zanussi dishwasher from showing i30 permanently?
A: The i30 clears automatically once the base tray is empty and the float switch drops. If it does not clear after draining and drying, the float switch itself may be stuck raised or faulty.
Q: Can foam from too much detergent cause i30?
A: Yes. Excess foam can overflow from the tub into the base tray and lift the float switch, triggering i30 even without a mechanical leak.
Q: Is i30 on a Zanussi dishwasher the same as i30 on a Zanussi washing machine?
A: Both relate to flood protection in the base tray, but the Zanussi dishwasher i30 and the washing machine anti-flood code are different in their specific mechanisms. This guide covers dishwashers only.
