Frigidaire Dishwasher Error Codes — Complete Error Code Diagnosis Guide

Eight Frigidaire dishwasher codes are decoded here, and two of them are about the console rather than the plumbing: Er is a membrane switch error and both it and ER1 can be produced by moisture rather than by a failed part. i10 is a fill timeout at a half-open shutoff or a scale-blocked strainer, i20 is a drain fault where the disposal knockout plug is a standing suspect, i30 is a leak in the base, i50 is the wash motor, i60 is heating, and iC0 is the turbidity sensor whose optical window has filmed over.

The guides are ordered around what can be seen before anything is measured. iC0 is a good example: an optical sensor reading through a greasy window behaves like a failed sensor, so cleaning comes before the part number. i20 asks about the knockout plug on a newly installed disposal before the pump is condemned. Er and ER1 both benefit from drying the console and letting a held pad release. i60 separates the element from the thermistor that reports on it, because a cold wash proves neither one on its own.

ER1 and i30 both mean water has already reached the base pan, and the float has done what it exists to do. Running another cycle to see whether the code returns is the one action that makes the situation worse. Power off at the breaker before the door gasket, the float assembly or a hose connection is disturbed — the cabinet is wet and live at the same time.
