TROUBLESHOOTING GUIDE
Satellite Does Not Heat
NOTE
reheat cold coffee.
1 First check to see if one of the LED bars on the satellite
indicates a bad heating element. The middle LED bar
controller (replace the controller).
2 Check to see if the Intellifresh LED on the front of the
satellite comes on at the beginning of the brew cycle. If
neither the LED nor the warmer come on, then it can be
assumed that there is no power to the satellite. Make
sure that power is being supplied to the Intellifresh
(IF) connector on the brewer when the BREW button is
the ELECTRICAL SCHEMATIC. If power is present at
the connector, check the connector contacts. If power
is not present at the IF connector, trace the circuit back
to the control module to see if it is supplying power to
the IF connector.
3 Check the contacts on the satellite IF connector to make sure that they are making good contact with the
connector on the brewer.

None of the LED Bars Light, Regardless of Coffee Level (Warmer is Working OK)
NOTE: If the satellite is empty, the LED bars will not light.
1 Check for chassis ground, UPM ground and UPM 5 Volts into the LED array (see LED pin assignment on
satellite schematic).
2 If power and ground are being supplied to the LED array and none of the LED sections come on when the
satellite is full, the LED array is probably bad.
Some LED Bars Do Not Light
Short the probe wire for the LED section that is not working to ground. If the section lights, check the probe
connection. If the section does not light, the LED array is bad.
One or More LED Bars are Constantly On Regardless of Coffee Level
Clean the inside of the satellite according to the CLEANING INSTRUCTIONS
1
build-up that may be causing a malfunction.
2 Check for a probe wire that is shorted to ground.
3 If the probe wires are OK, suspect the LED array.
IntelliFresh Feature Does Not Work (Warmer OK)
1 Check to make sure that the UCM IntelliFresh settings on the brewer are correct.
2 Check the continuity of the UPM/LED communication wire.
3 Replace the LED module. If the IntelliFresh feature does not work properly after replacing the LED module, the
satellite UPM module is probably bad.
