What i20 Means on a Frigidaire Dishwasher

Frigidaire says i20 indicates the dishwasher is not draining properly; its code guide calls it “unit did not drain completely”. Frigidaire’s checks: on a new install tied to a garbage disposer, the disposer knockout plug must be removed; the drain hose can’t be blocked, pinched or restricted; the hose must reach at least 32 inches above the floor; and the glass trap and filter must be clear of food soil. To reset, hold Cancel, switch off the breaker, or unplug the dishwasher for 3 minutes. Source: Frigidaire i20 (opens in a new tab).

Clearing i20 Step by Step

Turn the dishwasher off before reaching into the tub.

1

Clean the glass trap and filter

Lift out the glass trap and filter at the bottom of the tub, rinse off food soil and lock them back in.

2

Check the hose under the sink

Look for a kink or pinch, and make sure the hose loops at least 32 inches above the floor before it drops to the drain.

3

Reset and run again

Hold Cancel, flip the breaker, or unplug the dishwasher for 3 minutes, then run a short cycle.
