Here are some tips to follow if you're buying a dishwasher for your first restaurant.
Ensure the dishwasher is a commercial model, rather than a domestic one
Domestic dishwashers are almost always cheaper than commercial dishwashers. If you're on a budget, the lower cost of the former might tempt you to buy it. However, it is important to get a commercial version of this appliance for your restaurant, even if this means you have to spend a bit more.
