Samsung Error Codes: Washer, Dryer, Dishwasher & Fridge

Samsung appliances show short alphanumeric codes; newer models use a letter+C format (e.g. 4C) while older ones used a letter+E (e.g. 4E) for the same fault. Codes are consistent across many Samsung washers, dryers, dishwashers, and fridges. Find yours below.

⚠ Safety first. Unplug the appliance or cut power at the breaker before opening any Samsung washer, dryer, dishwasher, or fridge panel. High-voltage components and sealed refrigerant lines are licensed-technician work — don’t open those up yourself. A gas smell or scorch marks anywhere near the unit means stop and call a professional right away.
