Frigidaire Dishwasher Error Code i40: Meaning and Fix

A dishwasher reports its fault in the display window, or by blinking a cycle light a set number of times with a pause between groups. Count the blinks and pauses before opening the door. Frigidaire models show E, F or i codes depending on the appliance.

Frigidaire is an Electrolux brand and shares platforms with the Electrolux line. Washers and dryers use E codes, ranges use F codes, dishwashers use i codes, and refrigerators show SY codes. The codes apply to model numbers such as FGID2466QF, FFBD2412SW and FFRE4120SW; check the label on your unit to confirm yours.

What does the i40 code mean on a Frigidaire dishwasher?

The wash water temperature did not rise as expected.

Can I fix the i40 code myself?

Start with the free checks (power reset, connectors, obvious blockages). The likely repair involves the main control board and live-circuit testing, so if the code returns, a qualified technician is the safer call.

How do I clear the i40 code?

Switch off the dishwasher breaker or hold Cancel/Drain, wait a few minutes and run a short rinse. If i40 comes back, the underlying fault is still there; start with this: open heating element.
