Frigidaire Dishwasher Error Codes: Complete Guide to Every Fault Code

Quick Answer

Frigidaire dishwashers are built on the Electrolux platform and use a unique I-series code format (I20, I30, I40) that no other major brand shares. The most important Frigidaire-specific diagnostic fact is the polystyrene base pan float used for I30 (leak detection).

Frigidaire dishwashers are built on the Electrolux platform and use a unique I-series code format (I20, I30, I40) that no other major brand shares. The most important Frigidaire-specific diagnostic fact is the polystyrene base pan float used for I30 (leak detection). Unlike LG's resistance sensor or Bosch's mechanical float, Frigidaire's float sticks in the raised position due to detergent residue buildup, causing I30 to persist even after the actual leak is fixed. You must physically push the float down with your finger after clearing a leak. The most common codes are I20 (drain timeout, 280/mo), I30 (leak, 250/mo), E30 (dispenser fault), I40 (fill fault), and PF (power failure).

About These Frigidaire Dishwasher Error Codes

Frigidaire uses I-series codes on the Electrolux platform. The critical brand-specific fact: the I30 polystyrene float sticks from detergent residue and must be manually pushed down after fixing any leak. The float will not reset on its own.

Most Common Error Codes

Polystyrene base pan float stuck in raised position from detergent residue (I30)40%
Clogged drain filter or drain pump failure (I20)24%
Detergent dispenser solenoid failure (E30)14%
Power interruption mid-cycle (PF)12%
Inlet valve failed or low water pressure (I40)10%

Symptoms You May Notice

  • I-series or E-series code displayed on control panel
  • Dishwasher stops mid-cycle
  • No draining, no fill, or no heating
  • Door lock not engaging
  • Cycle interrupted by power flicker

How to Identify Your Error Code

1

Write down the exact code displayed

Write down the exact code displayed. For I30 specifically, do not assume the leak is still active. Open the kick plate and manually check the polystyrene float in the base pan - if it is in the raised position, push it down with your finger. A stuck float is the most common reason I30 persists after an actual leak has dried.

Frequently Asked Questions

Why do Frigidaire dishwashers use I-series codes instead of F/E codes?
Frigidaire dishwashers are built on the Electrolux platform, which uses its own fault code system. The I-series (I20, I30, I40) is specific to Frigidaire and Electrolux machines and is not shared by Whirlpool, Bosch, LG, or Samsung platforms.
Why does I30 come back even after I fixed the leak on my Frigidaire?
Frigidaire uses a polystyrene float in the base pan for leak detection. This float can stick in the raised (triggered) position due to detergent residue coating the float or its mounting channel. Even after the leak is fixed and the base pan is dry, the float remains raised and I30 keeps appearing. Open the kick plate and physically push the float down with your finger to reset it.
How do I enter diagnostic mode on a Frigidaire dishwasher?
Press and hold High Temp Wash and No Heat Dry simultaneously for 3 seconds. The display will show any stored fault codes. This works on FFCD2413US, FGID2479SF, and most other current Frigidaire dishwasher models.
