Electrolux Dishwasher Error Code i30 — Leak Detected (Anti-Flood)
What this means
The i30 error code on Electrolux dishwashers is an anti-flood safety code. A float switch in the base pan has detected standing water, meaning there is a leak somewhere inside the machine. The dishwasher will stop all operations and activate the drain pump to remove water. Common leak sources include loose hose clamps, a cracked sump, a leaking inlet valve, a damaged door gasket, or a worn tub seal.
Alternate codes: I30, i 30
Step-by-step fix
4 stepsTurn off water and power
Turn off the water supply valve under the sink and disconnect power to the dishwasher (breaker or unplug). Place towels around the dishwasher in case of additional leakage when moving it.
The dishwasher's drain pump may have already expelled most of the leaked water, but prepare for residual water.
Access the base pan
Carefully pull the dishwasher out from under the counter. Tilt it back slightly and look under the base. You should see standing water around the float switch. Soak up the water with towels.
The float switch is a small styrofoam block on a lever — make sure it can move freely after drying the area.
Locate the leak source
With the base dry, turn the water supply back on briefly and watch for where water appears. Common leak points: water inlet valve connections, drain hose connections, the sump gasket at the bottom of the wash tub, and the door gasket.
Shine a flashlight from different angles. Water trails and mineral stains will help trace the leak path.
Repair the leak
Tighten loose hose clamps, replace damaged hoses or gaskets, and fix the leak source. Dry the base pan completely, make sure the float switch moves freely, and slide the dishwasher back in. Run a short test cycle while monitoring for leaks.
If the float switch is stuck in the raised position due to mineral deposits, clean it to allow proper reset.
When to call a professional
If the leak is coming from the wash motor seal or a cracked tub/sump, these are complex repairs best handled by a professional.
