VPI H-16.5 record cleaning machine power failure

I purchased an unused machine secondhand (the guy died before using this, and his estate simply wanted to sell it on). Well, on getting this home, it worked fabulously for about ten LPs, then power failed. I'd treated the machine with the utmost care, drained the excess fluid etc.

I discovered that the onboard fuse had blown, since replaced. The main fuse in the plug was also replaced, though had not blown. But both switches (vacuum motor, and platter) still fail to switch on. What, I ask, could cause both to fail? 

And, is this machine what it's cracked up to be? In terms of build quality?
