There's no functional reason to buy matching appliances. Unless you're buying some kind of high-end kitchen rig with linked computer systems that as far as I can tell hasn't even been invented yet, your Maytag dishwasher will be perfectly happy chugging along next to your Kenmore oven and your Bosch microwave.
We take responsibility for the solutions we offer because we know they work. We will be happy to provide online or on-site advice, and our customers can be sure that the products will be compliant. Our systems have been tested by independent laboratories and by experienced professionals.
