- Water valves are not fully open
- Inlet hose is bent, frozen, or restricted
- Inlet mesh filters are clogged
- Household water pressure is too low
Quick checks, in order
Open both supply valves fully
Confirm hot and cold valves are open where both are connected.
Inspect inlet hoses
Straighten kinks and check for visible compression or freezing.
Test household water flow
Run a nearby tap to confirm normal pressure.
Clean inlet mesh filters
Unplug the washer and close water valves before removing hoses. Follow the model manual.
What happens during filling?
No water enters
Check closed valves, disconnected supply, frozen lines, and inlet-valve failure.
Water enters very slowly
Focus on pressure, kinked hoses, and clogged inlet filters.
Water enters normally but 4C returns
A flow sensor, inlet valve, wiring, or control issue may require service.

Frequently asked questions
Can low water pressure cause 4C?
Yes. The washer must reach a target water level within a set time, and low pressure can trigger the code.
Is 4E the same as 4C?
On many Samsung washer ranges, both codes refer to a water-supply problem, but model-specific manuals should be checked.
