I'm shopping for a new dishwasher and am curious: What's the benefit of a stainless steel dishwasher interior over a plastic interior?
The main benefits are noise reduction, durability and the ability of the stainless steel to withstand higher temperatures. Plastic tub dishwashers can only withstand water that reaches 140 degrees, whereas a stainless tub can handle water up to 160 degrees. The other benefit is that because the stainless steel can hold the heat, it will cut down the energy used in the drying cycle, making them a little more energy efficient. Hope this helps!
