TROUBLESHOOTING GUIDE
• Failed pump, needs to be replaced.
• Brew valve may have med out (error BRBV0#). Turn brew group o to reset.
No Brew Pressure; Pump/Motor is NOT Running
• Pump relay failure. Inspect the relay.
• Pump is locked or has failed.
• Motor has failed.
Brew Temperature
Readout for Brew Water Temperature Varies by a Few Degrees:
• The control must detect a temperature one increment (0.5°F on original machines, or 0.1°F on current
machines) above the set point before it sends a signal to turn o the heang element. This will allow the
electronics to show a reading just above the set point. The energy from the heang element and the tube
for the preheated incoming water are within 1” (25mm) from the locaon of the temperature probe in
the brew tank. The pick up tube for brew water is at the top of the brew group and is in the most temper-
ature stable water in the tank. The readout can show a temperature of a few degrees above your set
point, but your brew water is actually at the set point.
Brew Temperature Reads Low (error BRUT0#):
• Be sure to allow 20-40 minutes from the me the machine is powered up as the temperatures need to
stabilize. Ambient temperature and airow can change how quickly the machine reaches stability.
• Make sure the set point has not been changed.
• Check the programming in the handheld controller to ensure the brew elements are ACTIVE.
• Have a technician perform further diagnoscs.
Brew Temperature Reads High (error BROT0#):
• Display temperature will climb during brewing as hot water from the steam tank heat exchanger enters
the brew tank. This is normal and the water dispensed will be at your set point, not the displayed tem-
perature.
• Make sure the set point has not been changed.
• Have a technician perform further diagnoscs.
Electronics
All Tanks Read LOW:
• Check to make sure the element breaker is ON. Tanks will read low unl the temperature in them reach-
es 175° F. Please allow 20-30 minutes to heat up inially.
