REMEDY
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
