Frigidaire Dishwasher I30 Error Code: Leak Detected

Quick Answer

I30 is Frigidaire's signature leak detection code, and the most important Frigidaire-specific fact is that the polystyrene float in the base pan sticks in the raised position due to detergent residue. After any real leak is cleaned up and the base pan is dried, the float remains physically stuck upward and continues to trigger I30.

I30 is Frigidaire's signature leak detection code, and the most important Frigidaire-specific fact is that the polystyrene float in the base pan sticks in the raised position due to detergent residue. After any real leak is cleaned up and the base pan is dried, the float remains physically stuck upward and continues to trigger I30. The fix that most Frigidaire techs miss: open the kick plate and manually push the float down with your finger before assuming the problem is still active. This single step resolves I30 in many cases where the leak was already fixed.

What Does the I30 Code Mean?

Frigidaire I30 uses a polystyrene float that sticks raised from detergent residue. After fixing any leak, you must manually push the float down through the kick plate opening. It will not reset on its own.

Based on aggregated repair data, here is the probability breakdown for this error code:

Polystyrene float stuck in raised position from detergent residue (most common)40%
Door gasket leak at lower front corners24%

Sump seal failure allowing water under the tub14%

Symptoms You May Notice

  • I30 displayed on control panel
  • Dishwasher stops mid-cycle or will not start
  • No visible puddle under unit in stuck-float cases
  • I30 persists even after cleaning up a previous leak

Can you reset a Frigidaire dishwasher to clear the I30 code?

After manually pushing the float down and confirming the base pan is dry, press Cancel/Drain to clear I30. The code will not return if the float is down and the pan is dry. For a full reset, unplug for 60 seconds. Clean the float mounting channel with a soft brush to prevent future sticking.

Remove the kick plate at the base of the dishwasher (2-4 screws). Look into the base pan and locate the polystyrene float - a small white plastic cylinder approximately 2 inches tall. If the float is in the raised position (up), push it firmly down with your finger. Dry any visible moisture with a cloth.

Frequently Asked Questions

Why does Frigidaire I30 keep coming back even after I cleaned up the water?
The polystyrene float in the Frigidaire base pan sticks in the raised position from detergent residue coating the float channel. Even with the base pan completely dry, the float stays up and keeps triggering I30. Open the kick plate and push the float down manually - this is the fix that service technicians perform as their first step.
How do I prevent the Frigidaire I30 float from sticking again?
Clean the float and the plastic channel it rides in with a soft brush and warm water every 6 months. Using the correct dishwasher detergent in the recommended amount reduces residue buildup. Over-filling the detergent compartment is the main cause of residue accumulation in the base pan.
Can I run my Frigidaire dishwasher with I30 showing?
No. I30 causes the dishwasher to shut down to prevent water damage. If you have confirmed the base pan is dry and the float is just stuck, push the float down and clear the code before running a cycle. Do not force the dishwasher to run with an active I30 as it indicates potential water damage risk.
