What is the Samsung Washer 4C error?#
The 4C code means your Samsung washer started a cycle but water is not filling the drum — a supply problem. The machine expected water within a set time, did not get enough, and flagged 4C at the start of the wash. The usual reasons are mundane: a supply tap left partly closed, a clogged inlet screen, or a kinked fill hose. It is not damaging the machine, just stopping it. Before assuming a part failed, check that both water taps behind the washer are fully open.
4C on a Samsung Washer: likely causes and repair cost#
On a Samsung Washer, the 4C code signals: water not filling.
| Likely cause | Typical likelihood |
|---|---|
| Water supply off | Most common |
| Inlet valve clogged | Common |
| Kinked hose | Less common |
Typical professional repair: $100–$250 · Difficulty: moderate · often owner-fixable
Fastest thing to try first: Check water supply valves are open.
Symptoms that often accompany 4C: Washer starts but no water enters the drum; Very slow fill times (10+ minutes); Error appears at the beginning of the wash cycle
Technician diagnostic sequence for 4C:
- Check that both hot and cold water supply valves behind the washer are fully open — turn counterclockwise to the stop
- Disconnect the inlet hoses from the back of the washer and check the mesh filter screens inside each valve inlet. Clean any sediment or mineral buildup with an old toothbrush and vinegar
- Inspect the hoses for kinks, especially if the washer was recently moved. Even a partial kink dramatically reduces flow
- If supply is good and screens are clean, the electric water inlet valve may be failed. Test it by applying 120V AC to each solenoid — you should hear a click and water should flow. No click = replace the valve
Parts a technician may check or replace: Samsung DC62-00142G; included with new hoses; Stainless steel braided fill hoses if rubber hoses are cracked
Field note: Sacramento and Bay Area hard water frequently clogs Samsung inlet valve screens in 2-3 years. If you service Samsung washers in these areas, always carry spare screens and recommend the customer install a sediment pre-filter on the laundry supply lines.

How to troubleshoot the 4C error yourself#
4C is one of the more satisfying codes to DIY because the cause is often right at the hoses. Shut the taps, unthread the fill hoses, and clean the small mesh inlet screens where the hose meets the valve — mineral grit clogging those screens is a top cause in the table above. Straighten any kink in the hoses and confirm the taps open fully; low household water pressure will also trip 4C. Reconnect, reopen the taps, and restart. If water still will not enter with clean screens, open taps, and un-kinked hoses, the inlet valve itself may have failed — a "moderate" repair from the table above that a technician should handle, since it means disconnecting the supply and the valve wiring.
Is the Samsung Washer 4C error worth fixing?#
4C rarely becomes a big bill, which makes it worth resolving. Cleaning screens and un-kinking hoses is free, and even when the inlet valve needs replacing the table above lists $100 to $250 — on the lower side for a washer. Against a new machine that is minor, so there is no real replace-versus-repair debate: clear the supply restriction yourself, and if the valve is genuinely gone, the $100 to $250 fix is easily worth it on any washer worth keeping.

Samsung Washer 4C: frequently asked questions#
What does the 4C error mean on a Samsung Washer?#
It means water is not filling the washer within the expected time. Usually a closed tap, clogged inlet screen, or kinked hose is to blame, not a failed part.
Is it safe to keep using a Samsung Washer that shows the 4C error?#
Yes — the machine simply will not wash without water. There is no hazard, so you can troubleshoot the supply at your own pace.
Can I clear the 4C error myself, or do I need a technician?#
Very often yes: open the taps fully, clean the inlet screens, and straighten the hoses. Only a failed inlet valve requires a technician.
How much does it cost to repair the 4C error on a Samsung Washer?#
Frequently nothing if it is a supply restriction. If the inlet valve has failed, the table above lists $100 to $250.
Which parts usually fail when a washer throws the 4C code?#
Often none — it is a clogged screen or kinked hose. When a part fails, it is the water inlet valve from the table above.
Why does a closed water supply trigger the 4C error?#
The washer times how long filling takes; if the tap is off or flow is restricted, water never reaches the target level in time, so it reports 4C.
