What Does a Washer 4C Error Code Mean?

- Samsung

- WW90 series
- Code:
- 4C
Short answer
A 4C error on a Samsung washing machine means the machine is not detecting enough water flowing in during the fill stage. It usually points to a closed water tap, a kinked or blocked inlet hose, or a clogged inlet filter rather than a mechanical fault.
Error and fault codes can mean different things depending on the brand, model and production year. Always confirm the meaning in the official user manual for your specific model.
