This guide shows how to take apart the Barista to get to the boiler for either repair or maintenance.

The boiler heat the water to the needed temperature for both the steam wand and portafilter. If your machine isn't heating up, one possible cause is a failed heating element inside the boiler. This guide will show you how to test for this.

  • Make sure the machine is turned off and unplugged.

  • Set your voltmeter in continuity mode and place the leads on the two 90 degree prongs on the boiler's heating element.

  • It does not matter which lead touches which prong as you're just testing for a break, or "open" in the heating element circuit.'''

  • If the voltmeter shows 0, or "open", then there is an issue with the heating element's continuity and it needs to be replaced.

  • If given a reading, then your heating element is fine.

I did this a few months ago and the boiler was full of rusty gunk. This guide sure did help me out.
