Hi @craiggessell ,

Disconnect the power to the machine and then open it up an use an Ohmmeter to check if the 230V AC switch - part #80 has continuity, when operated. (or if you have the 115V AC model, the 115V AC switch - part #73 is OK - (here is the parts list for the 115V model).

If they’re OK then you may have to check the control board for any damage etc. There is no mention of a fuse in either parts list but that doesn’t mean that there isn’t one.
