GRINDER unit suddenly quit working overnight as if no power

Normally when pressing ONLY POWER button, grinder works. One morning it stopped working. When pressing POWER, there is only a faint “tick” sound. I can physically rotate grinder shaft from top of unit (with a little effort, but it does rotate). I read somewhere possible stuck switch or ?short? somewhere. Does ANYONE have a wiring diag on this thing? Cuisinart Cust Svc and/or Support SUCKS! —== Chaz ==—
