Samsung washer 4C error: a water fill guide

Samsung connects 4C with a fill problem. Start with visible water supply checks, and seek service if the washer still will not fill.

What it means

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

  1. Check that the water supply valves are fully open. [Samsung US]
  2. Check that the visible water supply hoses are not bent, kinked, or pinched. [Samsung US]

Should I reset a Samsung washer showing 4C?

A reset may temporarily clear 4C, but it does not fix the underlying water fill problem. [Samsung US]

Samsung warns that another reset can erase error history and make diagnosis harder. [Samsung US]

Before you try more

  • 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]

Find your model's manual

Copy the full model number from your washer's label, then enter it on Samsung's US support site. Open the matching user manual for the controls and instructions specific to that machine.
