In a commercial kitchen, the last thing you would want to see happen is your dishwasher breaking down. A dishwasher plays an important role in the activities of such an establishment. You cannot be expected to continue serving clients if you do not have clean dishes. You have no choice than to call in the repair services the fastest you can. They may get it fixed, or you may have to buy another machine. You only think of getting another one when you have to, since you cannot know for sure if it shall survive any longer. You therefore need to understand how to spot a machine that has long lasting parts in it.
You should first and foremost shun any that comes with plastic components in it. You may hear claims of long operation hours, but plastic will not withstand hat a commercial kitchen dishwasher has to go through. They shall not live through the many cycles of high temperatures that the dishwashers normally operate at. The best a machine with plastic components can do is serve in domestic settings.
A machine with stainless steel parts is the way to go. This one shall withstand as many operation cycles as possible without any of its parts giving in to the high temperatures. You also benefit from its resistance to the buildup for limescale. When it finally does, removing it with chemicals is an easier process.
IT is important to note the region from which the machine originates. You need to aim to get one made by the best manufacturers in the business. They need to have a steady supply of stainless steel. This makes it easy for them to make great machines with great parts, and charge you a reasonable price for it. This is easy to tell, when you look at the well-known brands in the market that were made out of stainless steel. There are however lesser known names in the market, but which still make high quality machines and components. You only need to do your research well into those.
You also need to see what kind of warranties the manufacturer offers on their machine and the parts. The longer the warranty period, the more comfortable you shall be with that purchase. You are thus better off with the longest warranties you can find. You also need to find it easy getting in touch with them when there is an issue. If getting in touch with them is already trouble, you cannot be sure they shall attend to an emergency as soon as you would want them to. If an emergency arises, your business will be left to suffer.
