A dishwasher in a commercial kitchen is supposed to operate so well that there is no chance it can break down. A dishwasher plays an important role in the activities of such an establishment. If it ceases to work, your business may come to a standstill. You will need to get the repair services in quickly to come to fix it. They might do so, or suggest you buy a new one. You only think of getting another one when you have to, since you cannot know for sure if it shall survive any longer. It is thus important that you know how to spot a machine that has the right parts.
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 will have a hard time withstanding the high temperatures that such a commercial dishwasher is subjected to. The best a machine with plastic components can do is serve in domestic settings.
You need to buy one with stainless steel parts. With such a machine, you can be sure its parts will not break down as a result of all that heat. This also takes a longer time for the limescale to build up in it. In case it manages to, cleaning it off with chemicals will be an easy process.
You also need to see where the machine was made. It needs to have been built by the best manufacturers there are. They need to have a steady supply of stainless steel. This will have you assured of high-quality parts and assembly, as well as a reasonable price. This is easy to tell, when you look at the well-known brands in the market that were made out of stainless steel. IT is possible to find other manufacturers that are not as well-known but who still make theirs using stainless steel. You only need to do your research well into those.
The warranties that accompany the machines and the parts are something you also need to watch out for. The longer the warranty period, the more comfortable you shall be with that purchase. You, therefore, need to aim for those that offer long periods of warranties. You also need to have an easy time reaching them whenever you have an issue. If the supplied customer care numbers are not working properly, you cannot trust they will do a good job with your machine. You thus need to be sure they shall respond favorably if and when there is a problem.
