Frigidaire Dishwasher · Code i20

Frigidaire Dishwasher i20 code: Did not drain

The dishwasher couldn't drain all the water out of the tub.

Most common causes

  1. Knockout plug still in place on a newly installed garbage disposal
  2. Drain hose kinked, pinched or clogged
  3. Drain hose not looped high enough (Frigidaire calls for at least 32 inches off the floor)
  4. Clogged filters

What you can safely check yourself

  1. If the disposal is new, make sure its dishwasher knockout plug was removed.
  2. Check the drain hose under the sink for kinks, and make sure it loops up at least 32 inches from the floor.
  3. Clean the filters at the bottom of the tub.
  4. Reset by pressing Cancel, or unplug the dishwasher for about three minutes.

Unplug the appliance before moving or cleaning anything. Do not open panels, touch gas connections or bypass safety switches.
