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?
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.

Electrical Tips to Help You Wire it Right
The Safest Way to Test Electrical Devices and Identify Electric Wires!
The Non-Contact Electrical Tester
This is a testing tool that I have had in my personal electrical tool pouch for years, and is the first test tool I grab to help identify electrical wiring. It is a Non-contact tester that I use to easily Detect Voltage in Cables, Cords, Circuit Breakers, Lighting Fixtures, Switches, Outlets and Wires. Simply insert the end of the tester into an outlet, lamp socket, or hold the end of the tester against the wire you wish to test. Very handy and easy to use.
The Quickest Way to Check for Faulty Electrical Wiring!
The Plug-In Outlet Tester
This is the first tool I grab to troubleshoot a problem with outlet circuit wiring. This popular tester is also used by most inspectors to test for power and check the polarity of circuit wiring.
It detects probable improper wiring conditions in standard 110-125 VAC outlets
Provides 6 probable wiring conditions that are quick and easy to read for ultimate efficiency
Lights indicate if wiring is correct and indicator light chart is included

Strip Off Wire Insulation without Nicking and Damaging the Electric Wire!
The Wire Stripper and Wire Cutter
My absolute favorite wire stripping tool that I have had in my personal electrical tool pouch for years, and this is the tool I use to safely strip electrical wires.
This handy tool has multiple uses:
The wire gauges are shown on the side of the tool so you know which slot to use for stripping insulation.
The end of the tool can be used to grip and bend wire which is handy for attaching wire onto the screw terminals of switches and outlets..
The wire stripper will work on both solid and stranded wire. This tool is Very Handy and Easy to Use.
