I called to find out if they worked on front-loader washing machines. When he said they didn't, I asked if he knew of anyone else who might. He said no one worked on front-loaders because they were so much trouble. Then he questioned me about how I treated the machine, and started yelling at me about how much soap I was using (which I've heard can be a problem, so I use only one small scoop, about 2 ounces) and how it was a complete fallacy that my front-loader saved any more water than a top loader. I started to tell him that I was a water quality engineer and had done some research, until I realized that he had hung up on me (strange marketing technique – treat potential new customers like dirt). Needless to say I won't be calling him back for service on any of my other appliances.
