Never did it with such a machine, but with some of other manufacturers. It was useless. Some types have diagnose and self-test options. Anyway IMO except you're an experienced "tinkerer" and have a source for spare parts it's useless to try it yourself. Especially if the electronics have a problem or if some special parts are broken which only the company has a supply or know how it was programmed etc.
Therefore I'd contact the service of the company. This is also because the machine needs afterwards a calibration to be sure to reach the expected temperatures within the limits.
