Hard Food Disposal
The other night we were having crab for dinner and some of the shells were still on the plate, but we knew our dishwasher had this useful feature. About 2 minutes into the cycle, I hear this scary buzzing noise coming from the wash module, which really freaked me out, because I had never heard the disposer operate before, even when there were large egg shells in the water. Anyway, it did it's job and the shells were flushed down the drain. Also it is extremely quiet when it fills.
BTW, does anyone know if my QuietGuard 7 model comes with a bottom insulation pad, because it didn't, and I read somewhere that it should. I also think that my machine was tested at the factory.
