Frigidaire FGID2477RF3A Dishwasher i20 and i40 During Normal or Quick Wash

Treat I20 and I40 as separate drain-related observations, not as one combined fault. Frigidaire's dishwasher error guide defines i20 as a cycle that did not drain completely and i40 as a clogged filter or sump; the i20 checks emphasize the disposer knockout plug, drain-hose obstruction or pinch, hose height, and the glass trap/filter, while i40 points first to food soil in the glass trap and sump.
