Frigidaire Dishwasher Error Code i30: How to Fix It

The Logic Verdict

I watched Marcus from Tothepoint Tutorials clear his i30 by tilting the dishwasher about 45° so the water puddled in the overflow pan could pour out. The float/pressure switch instantly dropped and the control stopped thinking the tub was already full. Drain that pan first—it fixes most i30 alerts without touching the pump or boards.

What It Means

i30 is Frigidaire’s flood protection warning. A small float/pressure switch lives under the tub; when it sees water collecting in the base pan it tells the board to lock out the wash cycle and keep the drain motor running. Until that switch goes back to “dry,” the control will keep flashing i30.

Common Causes

• Water collecting in the base pan after a spill, leak, or oversuds event. The video fix works because tipping the cabinet lets that puddle drain away from the float switch.
• A stuck or damaged float/pressure switch below the tub that keeps reporting “full” even after you’ve dried the pan.

Step-by-Step Fix

1. Cut power and prep towels. Trip the breaker or unplug the dishwasher, pull the toe-kick, and slide the cabinet out a few inches so you can lean it safely without straining the hoses.
2. Tilt the dishwasher 45°. Just like in the video, grab the sides and lean the machine forward about halfway. Hold it there while water trapped in the base pan drains onto your towels or shallow tray.
3. Let the pan empty completely. Keep the unit tilted until the dripping stops, then set it upright and wipe any remaining moisture around the harnesses and insulation.
4. Restore power and run a test. Push the dishwasher back in, turn the breaker on, and start a quick wash. The code usually clears immediately once the float drops back down.
5. Check the float/pressure switch if the code returns. The same video calls out the small “press switch” mounted under the tub. Make sure its wiring is tight, the plunger moves freely, and replace it if it stays stuck in the “full” position.
