Quick Answer
I20 on a Frigidaire dishwasher is a drain timeout fault. The most common cause is a clogged filter - Frigidaire filters on the FFCD and FGID series sit at the bottom of the tub and can accumulate food debris quickly with daily use. After cleaning the filter, check the drain hose for kinks before testing the pump.
I20 on a Frigidaire dishwasher is a drain timeout fault. The most common cause is a clogged filter - Frigidaire filters on the FFCD and FGID series sit at the bottom of the tub and can accumulate food debris quickly with daily use. After cleaning the filter, check the drain hose for kinks before testing the pump. The drain pump (154568401) should read 10-18 ohms on a multimeter. If the pump reads outside this range, replacement is needed. Unlike LG's rear-positioned filter, Frigidaire's filter is typically at the center base of the tub and twists to remove.

I20 is a drain timeout. Clean the Frigidaire filter at the tub base first. If clear, check drain hose routing. Test drain pump at 10-18 ohms and replace 154568401 if out of range.
