Samsung Dishwasher Error Codes — Complete Error Code Diagnosis Guide

Twelve Samsung dishwasher codes are decoded here, including one that belongs to no other brand: 7E is a WaterWall reflector error, where the bar that sweeps water across the tub has jammed or lost its motor. Water level takes 1E, 9E and OC — a clogged filter or sensor, a tub that never reached minimum fill, and an overflow. 4C is the supply, 5C the drain, 3C the pump motor, HE the heater, tE the sump thermistor, LC water in the base, AE a board-to-board communication fault, and bE a stuck key.

The three level codes are the ones that reward reading before buying, because they describe the same water from different vantage points: a filter clogged enough to fool the sensor, a fill that fell short at a part-closed tap, and a valve that will not shut. Each guide names the check that separates them. 7E is worked mechanically, with the reflector track cleared and the motor watched, and AE is chased into the door-hinge harness where wiring flexes with every opening.

LC is the code that ends the investigation and starts the mop: water has reached the base, from a door seal, a hose, or a pump seal, and more cycles make it worse. Because Samsung parts are model-specific down to the part number, confirming the model before ordering matters more here than on most machines. Line voltage in a wet cabinet means the breaker comes off first. EasyBear services Samsung dishwashers across Sacramento and the Bay Area.
