Samsung Washer Error Code 4C: How to Fix It

The Logic Verdict

My Take: I watched Duct Tape Mechanic fix this on a top-load Samsung washer. He states that 60% of the time, this is just clogged inlet filters which is a free fix. If cleaning them doesn’t work, the Water Inlet Valve (solenoids) is likely cracked or faulty.

What It Means

The 4C code (sometimes displayed as 4E) indicates a Water Supply Error. The washer is trying to fill with water, but it’s not detecting a sufficient water level within a set time.

Common Causes

1. Clogged Mesh Filters: Sediment blocks the water intake screens (Most Common).
2. Bad Water Inlet Valve: The solenoids crack or fail electrically.
3. Kinked Hoses: The washer was pushed back too far, pinching the hose.
4. Taps Closed: The home water supply valves aren’t fully open.

Step-by-Step Fix

1. Clean the Filters (Try This First):
   • Unplug the machine and turn off the water supply.
   • Unscrew the hot and cold water hoses from the back of the washer.
   • Use needle-nose pliers to pull out the small mesh filters from the intake ports.
   • Clean them with a toothbrush and water. Reinstall and test.
2. Inspect the Water Valve:
   • If the error persists, remove the rear panel (usually 6 screws) and the top console (2 screws) to access the valves.
   • Look for cracks in the blue/turquoise plastic of the solenoids. Cracks indicate a bad valve.
3. Replace the Valve Assembly:
   • Disconnect the wire harnesses (take a photo first).
   • Remove the mounting screws and hose clamps.
   • Install the new valve assembly, ensuring the seals are seated correctly.
