4) Eliminate limescale
Lime scale buildup is a problem that can be fixed without using chemicals. Did you just ask “how”? Well, by using vinegar, which should be distributed in small quantities in the detergent tray and half a liter (17 oz) inside the drum. At this point, launch a washing program without laundry on the inside at least at 60 degrees. In order to prevent lime scale, add a teaspoon of baking soda to the detergent at every wash.
