Is i20 on a Frigidaire dishwasher an emergency?

Usually not an emergency. If it smells like burning, sparks, or trips the breaker, switch it off at the breaker and leave it off until it is checked.

What i20 means

“Unit did not drain completely”

— Frigidaire, Dishwasher Error Codes and Alarms Guide. Codes vary by model: check your dishwasher’s own manual.

Where i20 fits

In plain words, i20 is about draining — the water did not leave in the time the control allows, usually a blockage in the filter, hose or pump.

Frigidaire gives one other drain code for this dishwasher: i40 (Clogged filter or sump).

Next to i20 in Frigidaire’s table: Hd (Heat delay or heater on mode activated) and i40 (Clogged filter or sump).

What to try first

  • Check the disposer knockout plug is removed, the drain hose is not kinked and is at least 32 in high, and the filter is clean.

Safety: If it smells like burning, sparks, or trips the breaker, switch it off at the breaker and leave it off until it is checked.

How urgent is it?

At least THIS WEEK. fixRAgent treats this code as a this-week repair: the appliance has reported a fault, but the code alone does not point at a safety hazard. This is fixRAgent’s reading, not the manufacturer’s. A photo can raise it — water near wiring, scorch marks, a gas smell — but a code never lowers what the photo shows.

Who to call

Appliance repair. Have the model and serial numbers from the label ready — a photo of the label works.

Recalls and manuals

Check whether your model is under a safety recall on the U.S. Consumer Product Safety Commission’s site: cpsc.gov/Recalls. Your owner’s manual is on Frigidaire’s support site; search it with the model number from the label.
