Pressurestat and thermostats

Pressurestat, level probe and thermostats

Bezzera's manual says: if the machine is malfunctioning, do not try to repair it yourself; call technical assistance. Every BZ10 carries an anti-tamper seal that cannot survive opening the case, and Bezzera grants no warranty on a machine whose seal is removed or damaged (12 months from the invoice). Treat this as technician work.
