Frigidaire Dishwasher Error Codes

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 codes are honestly some of the most literal in the industry. If you see an I20, don't just swap the pump, check your sink tailpiece first. These machines are incredibly sensitive to suds and residue. What I see most in the field are codes triggered by maintenance stuff, like a clogged air gap or the wrong detergent, not actual part failures.

About These Frigidaire Dishwasher Error Codes

I've spent years explaining to homeowners that Frigidaire changed their whole logic system when they moved to the Electrolux platform. You're now dealing with I-series faults, and honestly that's a good thing. Most of these errors are triggered by simple blockages in the fine filter or a stuck float rather than a control board blowing out. Usually a $0 fix once you know where to look.

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

  • An I-series or E-series code sitting on the display, sometimes flashing, sometimes just solid and staring at you
  • Machine stops dead mid-cycle, usually right after the main wash or the initial fill, and won't restart without you clearing the code first
  • Standing water at the bottom of the tub that never drains, or a tub that just never fills up
  • Door latch won't catch or releases on its own partway through the cycle
  • Cycle restarts fine after a power outage but then stops again at the exact same point every time

Tools Required for Diagnosis

Phillips #2 screwdriverFlathead screwdriverTorx T20 screwdriverMultimeterSoft-bristle cleaning brushDry towels or shop ragsWork gloves (base pan edges are sharp)

Service / Diagnostic Mode

Hold High Temp Wash and No Heat Dry buttons at the same time for 3 seconds. Display will show the last stored fault code. Press No Heat Dry to scroll through additional stored codes. Press Cancel to exit.

How to Identify Your Error Code

Replacement Parts

If your diagnostic testing proves the component has failed, you will need a replacement. We recommend OEM parts over aftermarket for water-handling components.

Frequently Asked Questions

Why do Frigidaire dishwashers use I-series codes instead of F/E codes?
It comes down to manufacturing history. Frigidaire is owned by Electrolux, so they share the same platform and the same brain. These I-series codes are actually pretty helpful because they tell you exactly which system is failing, whether it's the pressure switch or the drain circuit. It's a much more precise system than the old flashing light sequences we used to deal with in the nineties, where you'd count blinks and hope you got the right number.
Why does I30 come back even after I fixed the leak on my Frigidaire?
That polystyrene float is basically just a chunk of Styrofoam on a bracket. If you've had any water in the base pan, it floats up and trips a switch. The problem I see constantly is that detergent gunk or old food particles make that foam sticky. Even after you dry out all the water, the foam stays stuck up against the top of the bracket. You've got to physically reach in there and pop it back down, wipe it clean, and confirm it moves freely before you reset the machine. Otherwise you'll be clearing I30 every other week.
How do I enter diagnostic mode on a Frigidaire dishwasher?
Hold down High Temp Wash and No Heat Dry at the same time for about three seconds. The display will show the last stored fault code. Use the No Heat Dry button to scroll through any additional codes stored in memory. I use this to figure out if the problem's been happening for a while or if it just started. If there's a string of the same code in there, that tells me it's been failing repeatedly, which usually points to a part, not a one-time fluke.
What does it actually cost to fix a Frigidaire I20 or I30 error?
Honestly, most of the time it's nothing. Cleaning the filter and popping the float down is free. If you actually have a failed drain pump, you're looking at around $60-90 for the part and maybe an hour of your time. A bad inlet valve is similar, usually $40-70. The only time costs get ugly is if the control board is involved, and that's usually $150-250 for the part alone. But control boards rarely cause I20 or I30 directly, so don't let anyone talk you into replacing it before ruling out the simple stuff.
Can I keep running my Frigidaire if I keep getting a PF code?
PF by itself isn't dangerous. It just means the cycle got interrupted by a power blip and you can restart it. The one thing I'd watch for is PF showing up repeatedly without any actual power outages in your house to explain it. That could mean the dishwasher's circuit is dropping voltage when the motor starts pulling current, which stresses the control board over time. If it happens more than two or three times without a storm or outage behind it, get an electrician to check the circuit before you end up with a fried board.
