Burkett Restaurant Eqiupment and ACityDiscount.com are two merchants that sell used commercial dishwashers. Entrepreneurs who are just opening a restaurant can save with used appliances and upgrade when the business is more profitable.
As of March 2015, one of the pricier used dishwashers is a Hobart CRS66A High Temperature Conveyor Dishwasher listed at $7,036. This moves racks automatically through the prewash areas over to the clean dish table. The wash tank has two stainless steel wash arms featuring nozzles with large-enough openings to direct water at surfaces.
Another option is a CMA-180UC High Temp 14 1/2 inch Opening Under Counter Dishwasher. Listed at $1,975, this is a more basic model that features a pumped drain and operates at 30 racks per hour.
