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
and 3 of the J5 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 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 21 & 22)
Plumbing lines should not rest on
the counter top.
The brewer must be connected to
a cold water supply.
Remove the tank lid and clean
inside of tank with a deliming agent,
if necessary.
