M4D: Checking Inlet Power

Below are photo instructions for checking the inlet power on a Macap M4D espresso grinder. This is useful if the grinder is intermittently not initializing when plugging the machine in and turning the power switch on.

Before doing this we recommend unplugging the grinder. While checking the connection points we recommend having compressed air on hand to clean out any potential grinds or dirtiness at the electrical connections. Tools required:

  • Phillips screwdriver
  • flathead screwdriver
  • compressed air
