What is this symptom?

Is your Zanussi Dishwasher leaking water during cycles? This common issue can manifest as water pooling underneath or leaking from the front. Often caused by a worn door gasket, improper leveling, or faulty hoses, addressing the problem quickly can prevent further damage to your kitchen.

Important Tips for Zanussi Models

  • Zanussi models have anti‑flood leak detection (error code i30/AL4) that may activate when water is detected in base tray; drying base and ensuring seals/hoses are correct can clear this state.

How to Identify: Water pooling at the front near the door bottom, visible cracks/tears in gasket or loss of flexibility.

Part: Door gasket/ seal

Unit not level or improperly installed

How to Identify: Appliance tilts forward; water flows towards door & leaks; use a spirit level to check.

Part: Dishwasher leveling feet

Loose, kinked, or disconnected water supply or drain hoses

How to Identify: Water leaking from underneath; visible loose or kinked hoses behind unit.

Part: Supply hose, drain hose, hose clamps
