Common Electric Appliance Repair – Espresso Machine

Inspecting and Repairing an Espresso Grinder
Background: Rob, a Handyman from Eugene, OR
Question: I have an electric motor that goes to a La Marzocco espresso grinder. The grinder burrs will not spin when the motor runs, and the fuse breaks after about 6 seconds of running the motor. What could the issue be?

Dave’s Reply:
Thanks for your electrical question Rob. It is very possibly that the motor is jammed where something is preventing the motor from spinning and the fuse is breaking to protect the motor from burning up. The first thing is to unplug the unit and carefully inspect any external moving parts such as the grinder blade or mechanism. If all the external parts appear to be normal then I would unplug the unit and carefully disassemble it so I could clean and inspect the moving parts looking for the cause which is preventing the motor to spin freely. I have found that using a one inch horsehair paintbrush is very helpful when cleaning appliances such as this. It should be noted that I do not use a nylon paint brush simply because nylon can produce static electricity which could damage any electronic circuitry which is so commonly found with most home modern appliances.
