Samsung CareGreetings!
It's frustrating when something doesn't work as expected right out of the box, especially after trying various troubleshooting methods. We are here to help you out.
I have shared a Samsung link below that will help with your experience. The link shared below can serve as a recap to the troubleshooting steps you may have gone through. Please take your time in step number 3 which indicates that electric dryers like yours require 240 Volts to heat, anything lesser than 220 Voltage may only run the motor and the control panel but not the heating element.
Clothes are not dry after using the Samsung dryer:
