You should now be able to see the top of the group. Now grab an allen wrench and take off the metal block that resides under the shower head. If it is stuck due to calcification or coagulated coffee compounds, use a small flathead screwdriver to pry it off. Remove the phillips screw from the shower screen, and then pull off the shower screen itself. You’ll see a phillips screw head in the middle of the shower screen. You should only need to remove the 3-way solenoid hose and the OPV hose at this point. To make life easier, remove all hoses from the machine. If you leave your wire assembly as-is after you unplug all connectors (don’t bend or crush the wires!) you should be able to easily see where all of the wires connected to for reassembly. You will need to detach the pump hose from the OPV and unplug all push-on connectors. Next, detach the electronics and pump from the machine. This will allow you to set the group down on a flat surface without damaging the copper pipe. Using a standard or crescent wrench, remove the chromed steam wand from the copper steam pipe. Note that things might get messy and/or moist very soon. Remove the boiler from the chassis and place it in a clean work area. I recommend numbering each of these connectors before pulling them off so you can easily reconnect them.įlip the machine over and use allen wrenches to remove the four bolts attaching the group to the chassis.Īfter removing these screws, your boiler should be free. You’ll also want to pull the push-on connectors off of the power connector on the rear of the machine, and pull all the cables off of the front switch. Yours should (hopefully) be centered in the hole. Note that the valve in the photo above is a bit offset, this is due to my machine being damaged. Next, pull the steam wand knob off (it might take a bit of effort). The top plastic water spout / sheet metal assembly should pull off towards the back of the machine. Note: You can buy citric acid at many bulk food stores for a reasonable price Remove the Boilerīegin by removing the two attachment screws on the top of the machine by the water spout. Citric acid or espresso machine cleaner.

Feel free to drop a comment if you have any questions or information to add.īefore you start out, I would recommend purchasing a few tools (most available at your local hardware store): I’ve written this guide as a teardown guide, but feel free to read it from bottom-up to get a clear understanding of how to assemble this machine. After realizing that it was not as “lightly used” as the seller denoted, I took apart the entire machine to clean it up. I recently purchased a used Gaggia Classic machine on Amazon.
