TROUBLESHOOTING (cont.)
PROBLEM PROBABLE CAUSE REMEDY
Water does not heat to proper tem-
perature (cont.)
IMPORTANT: Make sure no tem-
perature tests are taken before the
ready light is "ON". Tank tempera-
ture must be stabilized before read-
ings are taken.
6. Tank Heater Disconnect the brewer from the
power source. Check for continuity
between the white terminal of the
terminal block (or red terminal on
208/240volt models) and the black
wire on the relay on the control
board (Toggle Switch must be in
120/208-240V position on 208V &
240V models). There should be a
low OHM reading. If no continuity is
present, check for a wiring prob-
lem, then replace the tank heater if
no wiring problem is found. (See
