Low Temperature Dishwasher Buying Guide

Building an efficient warewashing area is critical to running a successful food service operation. However, before you start looking for the best commercial dishwasher for your business, it would be helpful if you first answer these questions:

  • What is my budget?
  • What kind of power outlet is available in the building?
  • Do I have a constant supply of hot water?
  • How much space do I have in my kitchen?
  • Do I serve greasy food like pizza or some light food like salads?
  • Do I serve delicate dinks that can be affected by chemical sanitizers?
  • How many dishes per hour do I generate?

The answer to these questions can help you decide, and we prepared a high temp dishwasher vs. low temp debate.

Low Temp vs. High Temp Dishwasher

Here are some key differences between low and high temp dishwashers so that you can evaluate advantages and disadvantages.

Operating Temperature Sanitizing Agent Electricity Outlet Additional Equipment Upfront Cost
Low Temp Dishwasher 120oF – 150oF Chemical sanitizers 115/120v Not required Lower
High Temp Dishwasher 180oF – 190oF Hot water 208/240v Condensate hood, booster heater for some models Higher

Both versions of dishwashers utilize the same temperature for the washing cycle, approximately 140oF to 150oF. The main difference occurs during the rinse cycle when sanitation takes place.

The high temp dishwashers use a minimum of 180oF to properly sanitize dishes, while low temp dishwashers use approximately 120oF. Low temp dishwashers use a chemical sanitizer to kill bacteria on the dishware, so basically, it comes down to heat vs. chemicals.

High temperature dishwashers use high heat during the rinse cycle also; it helps to break down animal and other fats, in conjunction with the standard machine wash detergent and rinsing soap. This type of dishwasher requires a booster heater to provide the constant supply of hot water. Luckily, many models have a built-in booster heater.

High temp ware washers produce a lot of steam, so having a condensate hood system is a must; for that reason, it is advisable to keep your dishwasher out of the guests’ area.

Low temperature dishwashers still use hot water in the washing cycle because heat helps remove debris and oily smudges. Once the dishware is clean, the machine uses powerful cleaning chemicals to rinse them and kill any remaining microorganisms.

Low temp dishwasher temperature must not be below 120oF, according to the National Sanitary Foundation (NSF) requirements. Temperature below that point will result in health department violation. Check your local codes to be sure you are following the correct guidelines.
