Samsung Dishwasher Error Code 3E: 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. Samsung codes combine a digit with a letter, and some alternate with the cycle time.
Samsung displays numeric-plus-letter codes such as 4C, 5E or 21E, and many models run a Smart Care self-check through the app. Washers and dryers often use letter pairs, refrigerators use number plus E. The codes apply to model numbers such as DW80R5061US, DW80K7050US and DV45T6000EW; check the label on your unit to confirm yours.
