Because warewashers have a number of components, the likelihood of breakdowns and failures is increased. By properly caring for these units with regular cleaning and routine maintenance, operators can expect them to have as much as a 10-year service life.

Consultant Q&A with Timothy A. Barker, founder of Table & Bar Consulting Group, Memphis, Tenn.

Rack warewashers, commonly referred to as rack conveyors, are often used in full-service restaurants and higher-volume applications, such as universities and healthcare foodservice. This is because the average production rate for these continuous-motion machines is between 100 and 300 racks an hour. While undercounter and door-type machines also use racks, this reference typically is limited to the conveyor-type units.
