Samsung describes 4C as a water fill error on its washing machines. [Samsung US]
Which models?
The cited guidance discusses Samsung washers generally. We have not verified a list of exact compatible models. Find your full model number and check its manual before following model-specific instructions.
Samsung’s US reset article identifies 4C as a water fill warning. Its separate water fill guide supplies the checks below. This page combines those two pieces of guidance into a short sequence; it does not claim that every Samsung washer uses the same code.
Before taking further steps, compare the exact code and full model number with your washer manual. The instructions below stay outside the machine. If the supply looks normal and the washer still will not fill, Samsung recommends service.
Low-risk checks
- Check that the water supply valves are fully open. [Samsung US]
- Check that the visible water supply hoses are not bent, kinked, or pinched. [Samsung US]
Before you try more
- Samsung says repeatedly resetting the washer can erase error history without fixing the water fill problem. [Samsung US]
- On some Samsung washers, a missing hot-water connection can cause a water supply error when the washer requests hot water. [Samsung US]
When to stop
- If the washer still does not fill after the supply checks, request service from Samsung. [Samsung US]
