When your Samsung dryer stops working or displays an error code, it’s trying to tell you exactly what’s wrong. Samsung dryer error codes are built-in diagnostic messages that help homeowners identify issues early, prevent damage, and determine when professional repair is needed.
This guide explains where to find Samsung dryer error codes, what each error code means, how to fix the issue, and how to reset your Samsung dryer safely.
Where to Find Samsung Dryer Error Codes

- Most codes include letters and numbers (for example: HE, tS, bE)

Please write down the error code before unplugging or resetting the dryer, as it helps with accurate troubleshooting.
