TS/TSR)
3. Control Board (CDBC & CEZ)
1. Plumbing lines
2. Water supply
3. Lime build up
A) Remove the probe from the grom-
met and submerge in a water bath
of approximately 70°F(21°C). Con-
nect 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 reading should be
9.3k ± 2k OHMS. If the probe is
within these parameters, reconnect
the J3 plug to the control board.
B) Remove the probe from the grom-
met and submerge in a water bath
of approximately 70°F(21°C). Con-
nect 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 reading should be
9.3k ± 2k OHMS. If the probe is
within these parameters, reconnect
the J5 plug to the control board.
Set the temperature to 200°F (95°C).
Let tank temperature stabilize. If
temperature in tank is above tem-
perature 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 in-
side of tank with a deliming agent, if
necessary.
