We are selling our beautiful espresso machine after 2 years of use in our restaurant. It saw very light use as this was a full service restaurant and not a coffee shop. We followed all La Marzocco operational procedures and cleaned the group heads with cafizza every night and in the middle of the day if it was busy. We recently sold our other GB5 this past week. It is an absolute workhorse and super reliable. It's water supply has been filtered with a commercial grade filter. This ensures that the water feeding this machine has been perfectly filtered to prevent the build up of scale. This will greatly extend the life of the water lines, small valves and the boiler. The panels are in great condition as seen in the photos.
