4. Multi-point Inspection
1. Perform a water drainage of the boilers
CAUTION: Once the water drainage routine is started the machine will allow hot
water to be released from the hot water wand, coff ee spout, and steam wand (if
applicable). Please exercise caution when activating the routine to prevent injury.
Perform a water drainage using the water drainage function in the programming
menus:
1. Insert Service Card and type your pin (1000)
2. Tap System - Test/Calibration - Water drainage
3. Confi rm that you would like to perform the water drainage
A timer will appear on the screen and start counting down once the automat
moves into brewing position. Once this timer is below 2:00 minutes turn off the
water supply and allow the system to depressurize. Remove power from the
machine once there is no water fl owing from the hot water wand (and steam
wand if applicable).
2. Once the water drainage is complete, turn off water supply and
power off the machine to begin checking the coff ee boiler for
calcium.
• Remove the coff ee boilet inlet and clean any additional calcium with
wire brushes.
Checking for calcium
CAUTION: Please be aware that the boiler and its components may still be hot.
Please exercise caution when handling any of these components.

Schaerer Coffee Art C - Generic 24mo Preventative Maintenance SOP
3. Remove all panels for the machine. Check for any leaks or broken
parts and briefl y clean up any dirty areas.
• If additional issues or maintenance/ repairs are needed, please
contact Tech Support and ensure a separate work order is
created outside of this service.
Once power has been removed, proceed with disconnecting the center boiler nut
as shown in the following illustration.
Coff ee Boiler
Once the boiler nut is disconnected, you will have the ability to insert your long
Schaerer screwdriver until it touches the metal at the bottom of the boiler.
• If you feel any crunching or debris inside which impedes the movement of
the screwdriver to the bottom of the boiler then you have calcium present.
• If you can insert the screwdriver and feel the metal at the bottom of the
boiler then your check inside the boiler is complete.
Please note: if you can insert the screwdriver to the bottom of the boiler and
don’t feel any calcium, this is not a guarantee that there is no calcium present.
4. Multi-point Inspection (cntd)
