I'm sorry to hear that have you tried to power cycle the washing machine does this still occur?
To power cycle the unit you can either unplug it or turn it off at the breaker for about 2 minutes.
Do you notice any error codes? When the icons flashing does it still allow the cycle to continue?
After completing those steps and going through all troubleshooting the unit will require service. You can use the following link to locate a service center in the area that can do the repair for you. https://www.samsung.com/us/support/service/
