Greetings!
We appreciate your question about the difference between heavy-duty and deep wash cycles.
Heavy duty cycle uses warm temperature water with a high level of water for heavily soiled laundry. The deep wash cycle uses warm temperature water with an extra high level of water (uses more water) for normally soiled laundry.
I have shared a Samsung link below that can help with explaining all the cycles and settings available with our Samsung washing machine models.

I have also shared this model’s user manual link below. Please turn to pages 33 and 59 for the cycle overview and chart.
