Samsung Washer 4C Error Code: What It Means and How to Fix It

What to try first

Safety: Turn both water valves off before you disconnect the hoses, and unplug the washer before you reach behind it.

1. 1

   Open both water valves all the way

   Open each tap behind the washer fully: round handles turn counterclockwise until they stop, and lever valves sit in line with the pipe when open. Samsung asks for both valves to stay fully open while the washer runs.

2. 2

   Check the hoses: hot to hot, cold to cold, no kinks

   Connect the hot supply to the hot inlet and the cold supply to the cold inlet, and straighten any bends where the washer was pushed back. Samsung says not to use Flood Safe hoses, which contain a shut-off meant to close if a hose bursts; swap them for standard washer hoses.

3. 3

   Check the drain hose depth

   Make sure the drain hose is seated in the drain pipe and not kinked. On digital-display models Samsung says it should go 6 to 8 inches into the pipe: deeper, or sealed airtight, and it creates a siphon. Leave the screw that holds the drain hose to the back of the washer in place.

4. 4

   Cut the power for one minute

   Unplug the washer or switch off its circuit breaker for one minute, restore power and run a cycle. If 4C comes straight back, the cause is still there.

5. 5

   Clean the inlet filter screens

   Turn both supply valves off, put a towel down and disconnect the hoses from the back of the washer. If you see debris in the inlet ports, carefully pull out the small filter screens, rinse them, put them back, reconnect the hoses and open the valves fully again.

Most likely causes of 4C

1. 1. A water valve that is closed or only partly open (most common)

   The code appears right after the washer was moved, or after plumbing work in the house.

2. 2. Hoses swapped, kinked, or the hot hose not connected (most common)

   The washer was recently moved or reinstalled, or 4C shows up on some cycles and not others, which points to a missing hot hose.

3. 3. Clogged inlet filter screens (common)

   Grit or scale sits in the small mesh screens inside the inlet ports, often after water-main work or in homes with sediment in the supply.

4. 4. Drain hose pushed too far into the drain pipe, or kinked (common)

   The hose was pushed down the drain pipe or sealed into it, so water siphons out while the washer is trying to fill.

5. 5. A failed water inlet valve or water level sensor (less common)

   Valves, hoses and filters all check out and water reaches the washer, yet the drum still does not fill and 4C returns.

When to call a pro

• 4C comes back after the valves, hoses, drain hose and inlet filters all check out.
• The hoses are full and the valves are open, but the drum still does not fill.
• The holder that keeps the drain hose against the back of the washer is missing. Samsung says this needs service.
• Water is leaking at the inlet connections or pooling under the washer.
