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 heang element. This will allow the

electronics to show a reading just above the set point. The energy from the heang element and the tube

for the preheated incoming water are within 1” (25mm) from the locaon 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 airow can change how quickly the machine reaches stability.

• Check that the element breaker is in the ON posion.

• Check that the relay is funconing properly.

• Check that the brew tank thermal overload switch has not been tripped.

• Check that the connecon to the temperature probe is intact and secure.

• Make sure the set point has not been changed.

• Check the programming in the handheld controller to ensure the brew elements are ACTIVE.

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.

• Check that the relay is funconing properly.

• Brew tank may be leaking. Check brew valve and ngs.
