What Does the 4E or 4C Error Code Mean on a Samsung Washer?
The Samsung washer error codes 4E and 4C both indicate a water supply problem — specifically that the machine isn't getting enough water, or water isn't entering the drum within the expected timeframe.
Difference Between 4E and 4C
On most Samsung washing machines, 4E (or 4C on newer models) both mean the same thing: a water inlet error. Newer Samsung machines renamed this error from 4E to 4C, but the meaning and troubleshooting steps are identical.
Common Causes of the Samsung 4E / 4C Error
- Water supply taps are closed — Check that both hot and cold supply valves behind the washer are fully open
- Kinked inlet hoses — Inspect the hoses connecting the washer to the wall valves for kinks or bends
- Clogged inlet filters — The small mesh filters inside the inlet valve connections can become clogged with sediment
- Low water pressure — Samsung washers need adequate water pressure (minimum 0.5 bar) to fill properly
- Faulty inlet valve — If the inlet valve itself has failed, it won't open to let water in
- Control board issue — Rarely, a malfunctioning control board misreads water flow and triggers the error
How to Fix the 4E / 4C Error Yourself
Step 1: Turn off the washer and unplug it from power.
Step 2: Check that both water supply taps are fully open.
Step 3: Inspect inlet hoses for kinks. Straighten any bends.
Step 4: Turn off the supply valves and disconnect the inlet hoses. Check the small mesh filters inside the hose connections — clean with a soft brush under running water if clogged.
Step 5: Reconnect everything, turn on the supply, and restart the wash cycle.
Samsung Diagnostic Test Mode
Samsung front-load and top-load washers have a built-in diagnostic mode. On most models, you can enter it by pressing and holding specific buttons (varies by model — check your manual). In diagnostic mode, you can test the drain pump, inlet valve, and other components individually to isolate the fault.
When to Call a Technician
If you've checked all the above and the 4E/4C error persists, the inlet valve likely needs replacement — a job for a certified appliance technician.
