As with all high powered electrical equipment...there can be a variety of issues that can cause a failure that looks similar to the one in your posted picture. I suggest you get in touch with your supplier to determine the bestmethod for getting the unit repaired quickly and efficiently.

These contacts are for sales representatives, and they should be able to direct you for the best service.
