One thing is certain. Whether you are running an office coffee machine or an industrial coffee machine, operational glitches are normal. Even new machines will have some problems but they are generally less than when you are used to working with office coffee machines and industrial coffee machines. Before you decide to invest in them you really need to evaluate your skills in the area of repairs and maintenance.
Ideally you should do a weekly check to see if there are even minor hiccups while running them. You can't make money if your machines aren't working as they should. Most people are willing to forgive an occasional glitch with an office coffee machine or an industrial coffee machine they use. If you don't have the necessary skills to fix your coffee machines you need to learn them. It is very important for the success of your business. It is also expensive to rely on an outside source to take care of this for you. Look for a good handyman who can take care of glitches and breakdowns.
You must take good care of proper maintenance of those machines. Regular and timely clean up using specialist-cleaning products and by professionals is necessary for quality control. Since any office coffee machine or industrial coffee machine uses liquids like milk and water, you need to be wary of possibility of contamination. In fact, if they are not cleaned regularly then coffee which is dispensed by them might smell a little fishy or taste sour. The cleaning process would include regular descaling depending on the kind of water you use.
Also it makes perfect sense to take advantage of the solid company warranties on each machine, and you will be assured of the possibility of quick repairs when needed. When repairs are needed which are not covered by the warranty, then you might benefit from having an AMC with the supplier or manufacturer of the office coffee machine. Though an industrial coffee machine is usually pretty steeply priced, the initial outlay works out since it is less likely to require much maintenance.
