TROUBLESHOOTING GUIDE

Dispenser Does Not Heat
NOTE
reheat cold coffee.
1 First check to see if one of the LED bars on the
sensor circuit on the controller (replace the controller).
2 Check to see if the Intellifresh
the dispenser 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
dispenser. Make sure that power is being supplied to
the Intellifresh (IF) connector on the brewer when the
on the model, see 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 dispenser 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 dispenser 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
dispenser schematic).
2 If power and ground are being supplied to the LED array and none of the LED sections come on when the
dispenser 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 dispenser 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
dispenser UPM module is probably bad.
