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 page 26)
