After washing in my new dishwasher the cups taste of detergent- why?

Cups may taste of detergent after washing in your new dishwasher due to several factors. One common reason is that the dishwasher is not rinsing thoroughly, leaving detergent residue behind. Additionally, using too much detergent or the wrong type for your dishwasher can exacerbate the issue. It's also possible that the dishwasher's spray arms are blocked, preventing proper cleaning and rinsing of the cups.
