The refrigerator in the photo is auto defrosting, I’m almost certain. Also, there’s a drive for some markets towards French door fridges and those leak a tremendous amount of energy. The energy saving parts also come with cost cutting, which is how I interpret the post. My 2001 era dishwasher was recently replaced with a 2024 model (in 2025) and the old one weighs nearly twice as much. They’re comparable in the product line of their time from the same manufacturer; the new one cost more. But it’s not just mass. It’s insulation, it’s metal parts replaced with plastic, nylon-glass fibre parts replaced with ABS and it’s thinning down components to last _just_ until the warranty expires. It doesn’t have a heat exchanger though. What kind of dishwasher?
