Samsung Washer nC Error Code: Causes and Fixes

Quick answer: On a Samsung Washer, the nC error code means the water supply cannot fill the drum — a no-fill fault. Samsung Washer nC is similar to the nF error code and indicates the machine cannot fill with water within the expected time. The nC code is seen on certain Samsung Washer models and indicates a general fill failure. Closed supply valves, kinked hoses, and clogged inlet filters are the most common causes.

Quick Fix for Samsung Washer nC

• Confirm both hot and cold water supply valves at the wall are fully open.
• Inspect both inlet hoses for kinks or sharp bends.
• Disconnect the inlet hoses and clean the mesh filters inside the machine’s inlet ports.
• Check the water pressure at the tap — run it and confirm good flow.
• Restart the cycle after addressing any supply issues.

Common Causes of Samsung Washer nC

• Closed supply valves: Hot or cold water valves at the wall are not fully open.
• Kinked inlet hoses: Hoses behind the machine are restricted.
• Clogged inlet filters: The mesh filters in the inlet ports are blocked with mineral scale.
• Low water pressure: Water pressure is below the minimum required (typically 14-116 PSI).
• Failed inlet valve: The water inlet valve solenoid has failed and will not open.
