GE Dishwasher Error Code i30: Anti-Flood Device Activated

The GE dishwasher error code i30 is a critical safety alert indicating the anti-flood device has activated. Water has been detected in the base pan where it shouldn't be, triggering immediate shutdown.

Anti-Flood Protection

GE dishwashers have a float switch in the base pan that detects leaks. When water accumulates from hose failures, seal leaks, or component cracks, the float rises and triggers i30. The dishwasher immediately stops all functions except the drain pump and won't operate until the leak is fixed and the base pan is dry.

Emergency Response and Repair

• Step 1: Allow the dishwasher to drain completely. The drain pump will run continuously when i30 appears.
• Step 2: Turn off the water supply valve under the sink to prevent continued flooding if a valve or hose is leaking.
• Step 3: Disconnect power once draining completes. You need to locate and repair the leak before restoring power.
• Step 4: Tilt the dishwasher backward at a 45-degree angle to drain water from the base pan. Have towels and a bucket ready to catch spillage.
• Step 5: While tilted, inspect all visible hoses, connections, and seals. Common leak sources include inlet hose connections, drain hose clamps, door gasket, and internal hose connections.
• Step 6: Check the water inlet valve for leaks. A stuck-open valve or cracked valve body causes continuous filling and overflow.
• Step 7: Inspect the tub for cracks, particularly around mounting brackets and stress points. Plastic tubs can crack from impact or age.
• Step 8: Examine all internal hose connections. Loose clamps or cracked hoses leak during operation.

Repair all identified leaks by tightening connections, replacing damaged hoses, or installing new seals. Let the base pan dry completely (24-48 hours) to ensure the float switch drops. Once dry, restore water and power, then run a test cycle while monitoring closely for any new leaks. The i30 error should clear once the base pan float switch resets. Never ignore i30 errors—they indicate active flooding that can cause serious water damage to your home.
