Had one of those in an apartment here. It's truth-in-advertising that it wasn't used to wash dishes, because it was could not, by definition. The only dishwasher that could soil clean dishes...
No not the only. I worked in a restaurant with a God awful Auto-Chlor DW. All it did was waste water and chemicals, break down constantly and send the dishes out dirtier than they went in! Did I mention that the pump was mounted below the drain sump so it could never truly drain. Thank God I was able to replace it with a Hobart.
