Samsung Dishwasher Error Codes — Complete List

Samsung dishwashers use the same lettering system as the company's washers, so a 4C still means a water-supply problem and an LC still means the leak sensor tripped. The difference is where to look — supply valves under the sink rather than taps behind the machine. These are the verified codes we cover, each with a full structured guide.

• LC (LE) Moisture reached the leak sensor in the dishwasher's drip pan — sometimes a real leak, but false alarms from a recent move, a spill, or even high humidity are well known.
• 4C (4E) The dishwasher isn't receiving enough water — start with the shut-off valve under the sink and the supply line before suspecting any failed part.
• 5C (5E, SC) The dishwasher couldn't pump its water out — the filter and sump catch most of the blame, with the drain hose and a never-removed disposal knockout plug close behind.
• OC (oC, OE) The dishwasher measured more water inside than any cycle should use — oversudsing fakes it, a stuck inlet valve causes it for real, and a sensor fault lies about it.
• HC (HE, 1E) The water inside exceeded the temperature any cycle should reach, which means the heater or its controls are misbehaving — a mains-voltage problem with no safe DIY path.
• 3C (3E) The circulation pump that sprays water around the tub didn't operate as commanded — restart once per Samsung's guidance, and if it returns, the pump needs professional attention.
• 9E The unit detected too little water while washing — sometimes a tall item is literally blocking or displacing the water path, otherwise the supply or level sensing is at fault.
• 7E The WaterWall reflector — the sliding bar that sweeps the spray across the tub — couldn't move, and the cause is usually tape, an obstruction, or the bar sitting off its rail.
• bE2 (bE) The control panel thinks a button is being held down continuously — residue and moisture cause most cases, a genuinely failed panel the rest.

Don't see your code?

Some compact Samsung models signal errors with blinking-light patterns instead of letter codes. If that's yours, count the pattern and check your model's manual rather than mapping it to the codes here.
