PRESS & HOLD CANCEL FOR 3 SECONDS, OR
RE-ENERGIZE THE BREWER (i.e. unplug for a few
seconds, the plug in again.)
* FROM “VALVE FAULT” ERROR: THE BREWER MUST
BE RE-ENERGIZED Using the CANCEL button will not

ERROR
LOW WATER TEMP
(Not an error)
LOW WATER LEVEL:
Inlet valve has been on
and no water sensed:
a. During regular
operation for 60
sec., or
b. during startup for
4-1/2 min.
VALVE FAULT:
Detection of a problem
with the wiring to the
valve or of the valve
switching system.
OVERHEAT:
Water temperature has
exceeded 210ºF
POSSIBLE PROBLEM & CORRECTIVE ACTION
1. Water has not reached Precise Temperature
for Brewing™. WAIT UNTIL WATER
TEMPERATURE HAS RECOVERED.
1. Sleeve on level sensing probe gasket is too
long or sensor not pushed down fully. Sensor
should protrude beyond sleeve 1/4”.
REMOVE TANK LID, CUT SLEEVE TO
PROPER LENGTH. MAKE SURE SENSOR
IS FULLY PUSHED DOWN.
2. Level sensor may be pulled out of tank.
REINSTALL SENSOR.
3. Wiring to sensor may be disconnected or
faulty. REPAIR WIRING
4. Level sensor may be encrusted with scale or
lime build-up. CLEAN SENSOR (use chemical
de-liming. Scraping or sanding will damage
the sensor.
5. Water supply may be shut off, or is incapable
of filling the tank in the allotted time.
RESTORE WATER SUPPLY.
1. Wiring to either inlet or dump valve not properly
connected. CHECK WIRING / CONNECTORS.
2. Controller has two switches for each valve, one
or both has been detected as failing on.
REPLACE CONTROL BOARD.
1. Brew temperature may be too close to max.
temp. Brew temperature should be no higher
than 205ºF. LOWER BREW TEMPERATURE
SETTING.
2. Triac may have failed on, and water continues
to heat even after controller has tried to turn
heating element off. CHECK TRIAC,
REPLACE IF REQUIRED.
3. Probe may be defective. TEST ACTUAL
TEMPERATURE TO VERIFY. REPLACE
PROBE OR REPAIR WIRING AS REQUIRED.
