What the Samsung 4C Code Means

The washer expected to see a normal rise in water level during the fill portion of the cycle, but it didn’t. This is usually caused by a supply-side issue (valves, hoses, screens, water pressure) or a setup issue (drain hose installation causing siphoning).

Common Symptoms

• Washer pauses early in the cycle and displays 4C
• Very slow fill or no fill
• Hot and cold water seem reversed
• You hear water enter briefly, then it stops
• Washer appears to fill but the tub never gains water (possible siphoning)

Safety First

• Turn the washer off before moving it.
• If you disconnect hoses, have a towel/bucket ready.
• Be careful not to overtighten hose fittings when reinstalling.

Quick Checks (Homeowner-Safe)

1) Confirm the hot/cold hoses are connected correctly

• Make sure hot goes to the hot inlet and cold goes to the cold inlet.
• If they’re reversed, the washer may detect a fill/temperature mismatch on some cycles.

2) Make sure the supply valves are fully open

• Open both hot and cold shutoff valves at the wall all the way.
• If one valve is partially closed, fill can be too slow and trigger 4C.

3) Check for kinked, crushed, or frozen hoses

• Pull the washer forward slightly and make sure hoses have a smooth curve.
• Replace bulged or damaged hoses (and avoid tight bends).

4) Clean the inlet screens (very common fix)

• Turn off both water valves.
• Unscrew the hoses from the back of the washer.
• Look inside the inlet ports for small mesh screens and gently rinse/brush away debris.
• Reconnect hoses and turn valves back on, then try a short cycle.

5) Check drain hose installation to prevent siphoning

• Don’t push the drain hose too far down into the standpipe (can siphon water out while filling).
• Make sure the standpipe/laundry sink drains freely (a backup can confuse filling/draining behavior).
• Confirm the drain hose height follows the washer’s installation guidance for your setup.

6) Confirm household water pressure is adequate

• If multiple fixtures are running (shower, sprinklers), pause them and try again.
• If the house has a pressure issue, 4C may show up more often during high-demand times.

7) Power reset

• Unplug the washer for 2 minutes, then plug back in and retry.
• If 4C returns quickly after basic checks, it may be a valve/sensing/control issue.

Most Common Causes (and Likely Parts)

• Supply valves not fully open or restricted household supply
• Kinked or damaged fill hoses
• Clogged inlet screens (sediment/debris)
• Water inlet valve assembly (valves not opening properly)
• Water pressure/flow sensing issue (model-dependent)
• Main control board (less common; usually after other causes are ruled out)

When to Call Beacon

Call Beacon Services & Appliances if:

• You’ve confirmed valves are open, hoses aren’t kinked, and inlet screens are clean—but 4C keeps returning
• The washer fills inconsistently (sometimes normal, sometimes no fill)
• You suspect an inlet valve assembly, sensing issue, or control problem
• You want a fast diagnosis without replacing parts blindly

Our friendly technicians in yellow can test water fill rates, verify valve operation, and confirm whether the issue is supply-related or an internal component. Request Service or call (352) 726-7530. You can also visit www.BeaconSaves.com.
