Yes. They manufactured all PermaTuf in Louisville. Porcelain dishwashers (Hotpoint and portables) were manufactured in Chicago or Milwaukee. Some dishwashers for the Canadian market were made of porcelain and were manufactured in Canada (at CAMCO, I assume). They had a high-performance design with a separate filter which they made in Canada for the Canadian market--it was likely before NAFTA and was more economical than importing the passive-filter PermaTuf.
