Samsung Washer Error Code 4C: Meaning, Causes, and Easy Fixes

What Does Samsung Washer Error Code 4C Mean?

Samsung washer error code 4C indicates a water supply problem.
Your washing machine is not filling with water properly within the required time.

This error is commonly seen on washing machines made by Samsung and is related to low water pressure, blocked hoses, or inlet valve issues.

Common Causes of Samsung Washer Error Code 4C

1. Water Supply Is Turned Off

The water tap connected to the washer may be partially or fully closed.

2. Low Water Pressure

If household water pressure is too low, the washer cannot fill fast enough.

3. Kinked or Bent Inlet Hose

A twisted hose restricts water flow and triggers the 4C error.

4. Clogged Inlet Filter

Sediment or debris can block the small mesh filter inside the inlet valve.

5. Hot and Cold Hoses Connected Incorrectly

Incorrect hose connections can confuse the washer’s fill cycle.

6. Faulty Water Inlet Valve

If the valve is damaged, water will not enter the washer correctly.

How to Fix Samsung Washer Error Code 4C (Step-by-Step)

Step 1: Check the Water Taps

• Ensure both hot and cold water taps are fully open

• Test water flow directly from the tap

Step 2: Inspect the Inlet Hoses

• Straighten any bends or kinks

• Make sure hoses are securely connected

Step 3: Clean the Inlet Filter

1. Turn off the water supply

2. Disconnect the inlet hose

3. Remove the small mesh filter

4. Rinse it under running water

5. Reinstall and reconnect the hose

This step alone fixes most 4C errors.

Step 4: Check Water Pressure

Samsung washers generally require 20–116 PSI of water pressure.
If pressure is too low, contact your plumber or water provider.

Step 5: Reset the Washer

• Unplug the washer for 5 minutes

• Plug it back in and start a new cycle

Can You Still Use the Washer With Error Code 4C?
