How to Enter Diagnostic Mode on a Frigidaire Dishwasher

Frigidaire dishwashers show i-codes on the display; the leak (i30) and drain (i20) codes cover most service calls.

Step-by-Step: Frigidaire Dishwasher Diagnostics

1
Read the i-code from the display (i10 fill, i20 drain, i30 leak, i50 heat/relay, i60 temperature).
2
i20: clean the fine filter and glass trap in the sump, then verify the drain path (air gap, disposer loop).
3
i30: water in the base pan — remove the kick plate, dry the pan, and find the source. The unit stays disabled while the pan is wet.
4
Service/test mode entry varies by control revision; the tech sheet in the door panel or behind the kick plate documents it.

💡 Good to know: i-codes carried over to many Electrolux-built models (same parent) — documentation interchanges between the brands.
