Upper Microswitch, Mazzer Automatic (Timer) Grinders This is the upper microswitch used in Mazzer's automatic, timer-driven grinders, the switch that tells the motor when to start and stop grinding. It ships complete with leads pre-attached; there are no serviceable parts inside, so replacement is the only fix once it fails. COMPATIBILITY Fits: Mazzer automatic (electronic-timer) grinder models INSTALLATION Technician-level job, requires opening the doser/motor housing and correctly re-routing and reconnecting the leads; not a beginner task. PRO TIPS If your automatic Mazzer won't start, runs continuously, or grinds only intermittently when you jiggle the doser, suspect this switch before the motor or control board, microswitches fail far more often and are a much cheaper fix.
