Draining Single Group
Time Needed: 10 Minutes
Tools Needed: #2 Phillips Screwdriver
3/8 Fitted Wrench
Step 1: Turn off machine and access ball valves
Turn off the machine by unplugging from the power source
Shut off the main water going to the machine
Remove the cup tray and set aside
Remove the front panel by unscrewing the 4 screws (two under the cup tray and two in the front)
Step 2: Drain the machine
Locate the two ball valves (hexagonal shaped silver pieces with black tabs)
The back ball valve is dedicated to the steam tank
The front ball valve is dedicated to the brew tank
With a wrench (or with your hands if the machine is room temperature) open the ball valves by moving the black tabs parallel to the hexagonal body
If there is pressure in the steam tank, only open the back ball valve a quarter of the way. Opening the valve all the way will result in flooding the machine
The brew tank will not drain just by opening the ball valve because it is in a vacuum
To break the vacuum, locate the brew gauge and follow the copper tubing to the neck of the tank
With a 3/8 fitted wrench, unscrew the compression fitting connecting the copper tubing to the tank, There might be some water that spills out, this is normal.
Once both tanks are drained, use a wrench to close both ball valves
Make sure to tighten the compression fitting back to the neck of the group head
The compression fitting should be put on hand tight then a quarter turn with a wrench
If the machine is staying off for an extended period of time, unplug the machine from the power source
