Why can't I use vinegar in this machine? User manual states no organic or natural detergent and no detergent with vinegar or baking soda.

Hi Beth, We appreciate your question about the use of vinegar or baking soda. Using vinegar or baking, just to name a few, will cause damage to the washing machine, especially the rubber parts as they (natural ingredients) will make them brittle. I have shared a Samsung link below to further give you details as to what detergent is best used with the washer.
