Frigidaire Dishwasher Error Code i30 — Leak Detected
What this means
The i30 error code on Frigidaire dishwashers means the leak detection float switch in the base pan has been triggered. Water has leaked from a hose connection, pump seal, or the tub itself into the bottom of the dishwasher chassis. This is a safety code — the dishwasher will stop all operations and activate the drain pump to remove water from the base pan.
Step-by-step fix
4 stepsTurn off water supply and power
Turn off the water supply valve under the sink. Turn off the circuit breaker for the dishwasher. Pull the dishwasher out from the cabinet to access the underside.
Place towels on the floor — water in the base pan will leak out when you tilt the unit.
Remove the base panel and inspect
Remove the screws holding the front kick panel and the base cover panel. Tilt the dishwasher back slightly to look underneath. Use a flashlight to find where the water is pooling and trace it to its source.
Common leak sources: door gasket, spray arm seals, hose clamps, water inlet valve connection, and pump seals.
Dry the base pan and reset the float
Use towels to soak up all water in the base pan. The float switch (a small Styrofoam or plastic float) must drop back to its resting position for the error to clear.
You can use a wet/dry vacuum to quickly remove water from the base pan.
Fix the leak source
Tighten loose hose clamps, replace cracked hoses, or reseat the door gasket depending on where the leak originated. Turn the water back on and run a short cycle while watching underneath for any new drips.
If the door gasket is torn or hardened, replace it. A new gasket should press flat and form a complete seal around the tub opening.
When to call a professional
If the leak is coming from the tub itself or the wash pump seal, these are complex repairs best left to a professional.
