LG Dishwasher Error Code CL: Meaning and Fix

Reading the dishwasher display
A dishwasher reports its fault in the display window, or by blinking a cycle light a set number of times with a pause between groups. Count the blinks and pauses before opening the door. LG codes are short letter pairs; a capital O differs from a zero.
LG appliances show short alphabetic codes (OE, IE, UE on washers, Er plus letters on refrigerators) and, on ThinQ models, a Smart Diagnosis option. LG also builds many Kenmore Elite units. The codes apply to model numbers such as LDF7774ST, LDT5678SS and DLEX3900B; check the label on your unit to confirm yours.
