Suprema - Operation & Service
If an overflow occurs during a hot chocolate cycle, the machine will stop immediately
(anywhere in mid cycle). If an overflow occurs during a coffee vend, the cycle will be
completed (without any pauses), and then the unit will stop.
A rear overflow will shut everything off, including the heater element. A front
overflow will shut off all motors and valves, but will leave the heater element active
until the water level drops below the level probes. Power to the element will then be
switched off.
The " " message appears immediately when the unit is powered up (if

been completely filled after five minutes.
There are two fuses in the fuse box. The 5-amp fuse protects electronics, motors and
valves. The 15-amp fuse protects the heater circuit.
There is only one limit switch for the brewer motor. This switch controls both the
pause and the home position. If the brewer does not read the home position, it will run
a dry cycle (no water or product) and stop once it reads the home position. If the home
position is not found within 24 seconds, the brewer motor will stop and an error
message will appear.
If the chocolate pump falls out of the home position, it will automatically cycle until it
reads the home position, and then it will stop. If the home position is not found within 8
seconds, the pump will stop and an error message will appear on the display.
If any blue component harness is not connected to the rear board, a message will appear
advising you of the problem. The system will be disabled until the harness is re-
connected (with the main power off).
The water tank does not have a mechanical level float and switch. It uses three water
level probes – two to activate the inlet valve and a safety probe in case the first two get
covered in lime/calcium (which causes the level in the tank to increase too high).
After a chocolate pump cycle is complete, the valve will open for 0.2 seconds to rinse
the chocolate components.
As a safety feature, if the "
