A) Remove the probe from the
grommet and submerge in a water
bath of approximately 70
°
F(21
°
C).
Connect an ohmmeter to pins 3
and 4 of the J3 connector. At
60
°
F(16
°
C) the reading should be
15.3k
±
2k OHMS, at 70
°
F(21
°
C)
the reading should be 11.8k
±
2k
OHMS, and at 80
°
F(27
°
C) the read-
ing should be 9.3k
±
2k OHMS. If
the probe is within these param-
eters, reconnect the J3 plug to the
control board.
B) Remove the probe from the
grommet and submerge in a water
bath of approximately 70
°
F(21
°
C).
Connect an ohmmeter to pins 2

°
F(16
°
C) the reading should be
15.3k
±
2k OHMS, at 70
°
F(21
°
C)
the reading should be 11.8k
±
2k
OHMS, and at 80
°
F(27
°
C) the read-
ing should be 9.3k
±
2k OHMS. If
the probe is within these param-
eters, reconnect the J5 plug to the
control board.
Set the temperature to 200
°
F
(95
°
C). Let tank temperature sta-
bilize. If temperature in tank is
above temperature setting by more
than 7
°
F, replace the control
board.(See pages 22 & 23)
Plumbing lines should not rest on
the counter top.
The brewer must be connected to
