How to Choose the Best Dishwasher for Your Restaurant
Selecting an appropriate dishwasher for your restaurant will make a difference when it comes to having enough clean dishes for your guests during a busy service and expenses. You need to start thinking about several factors before you make the big decision.
What Size Do I Need?
To properly size a dishwasher, you need to think about a couple of things. First, how many anticipated meals will be served per day at your restaurant? Second, think about the total number of dishes used per guest. Finally, a busy service turns over tables more frequently than a slow one so determine an average amount of tables turned. Here is a helpful graphic from our Dishwasher Buying Guide.
What Sanitizing Method is Best for My Facility?
There are two types of sanitizing systems for dishwashers that act in different ways.
High Temperature sanitizing uses heat to sanitize dishes and glassware. This type of dishwasher requires a booster heater to raise the temperature of a final rinse to 180°. When shopping for a dishwasher, make sure you check to see if a booster heater comes with the machine, or if you have purchase one separately. High Temperature sanitizing dries dishes more effectively and does not damage flatware or plastics. The only downside of high temperature sanitizing is that they use slightly more energy than a chemical sanitizing machine, but you don’t have to purchase chemicals.
Chemical Sanitizing uses a chemical bath to sanitize dishes and glassware. This method of dishwashing reduces water heating energy costs. Chemical sanitizing does require the monthly purchase of chemicals, and is less effective at cleaning when washing grease-laden wares. Dishes may not dry effectively when using chemical sanitizing if the humidity in dish room is too high.
Is Energy Efficiency an Issue?
Operators must be aware of the additional costs, or savings, of energy when selecting a dishwasher for their restaurant. Purchasing the most energy efficient dishwasher can have a big impact on overall energy use.
Dishwashers are rated on water efficiency by the gallons of water per rack washed. They can also consume up to one-third of the energy used in operations due to the cost to raise water temperature. Choosing a machine with lower water usage will help the operator increase efficiency.
Energy Star rates commercial dishwashers based on energy efficiency and water usage. If a dishwasher has an Energy Star rating they are on average 25% more energy and water efficient than standard units.

As you can see, there is a lot to think about and consider before you dive into purchasing a commercial dishwasher. How busy your service is, how many pieces a customer uses and what type of energy efficiency you want are all factors that go into deciding.
