Open valves do not establish correct incoming flow or the entire installation. After confirming both supplies are available, note visible hose kinks and the model’s drain arrangement. If those checks are correct and 4C returns, arrange diagnosis rather than replacing the inlet valve by assumption.
Selected Samsung washers code family. Confirm the exact model and displayed characters; similar codes on other appliances are not interchangeable.
Wait for motion to stop and the door or lid to unlock. Water may be hot. Isolate power and follow the exact manual before any user filter maintenance. Never open a filter against a full drum, force a lock or bypass an interlock.
Trace the supply and the reported state
Start by distinguishing no supply, slow supply and water that enters but is not retained as expected. A fill message alone does not locate the cause in the inlet valve. Recent plumbing work and a visible kink are useful external clues. If those are absent, the technician still needs the exact model and observed behavior before deciding whether the problem is hydraulic, sensing or control related.
| Observed state | Interpretation / next step |
|---|---|
| What the code narrows down | Open valves do not establish correct incoming flow or the entire installation. After confirming both supplies are available, note visible hose kinks and the model’s drain arrangement. If those checks are correct and 4C returns, arrange diagnosis rather than replacing the inlet valve by assumption. |
| What it does not prove | A display code is not a verified failed-part or compatibility diagnosis. |
Code-specific checks
Check household supply
Look for closed supply valves or an outage after plumbing work. Inspect visible hose routing without pulling the washer or loosening pressurized connections.
Compare the installation manual
Check that the supply and drain arrangement match the exact model. Use its dimensions; do not treat a generic hose-height number as universal.
Arrange further diagnosis
If supply is available and routing is correct, record whether no water or only a little water enters. Provide that observation to service instead of buying an inlet valve on speculation.
If the warning returns
Household supply off → restore safely
Visible restriction → correct per manual
Normal supply, recurring 4C → service.
When to stop and get help
Only carry out maintenance permitted in your model’s manual. For service, note the full model number and suffix, displayed code, selected cycle and what happened during the checks. Leave internal wiring, gas components, pumps and safety devices to a qualified professional. A symptom alone does not identify a failed part.
Is 4C a drain-pump replacement instruction?
No. It is a fill-related code in the referenced Samsung guidance; verify the exact display.
