Tank does not heat

•Low (long) electrode coated with lime or faulty.

•Connection from control board to tank body faulty.

•Connections from control board to heater relay faulty.

•Line voltage connections to heater relay faulty.

•Connections to remainder of heater circuit faulty.

• Heater relay faulty.

•Thermal cut-out tripped or faulty.

•Disconnect electrode wire at quick connect (purple wire). Connect a wire from the quick con- nect to the cabinet body. If heating begins, this is the error cause.

•Check to ensure connection (green wire) is secure.

•Check to ensure connections (gray and blue wires) are secure.

•Check to ensure connections (black and brown wires) are secure.

•Check to ensure connections from relay to thermal cut-out and from thermal cut-out to contactor and from contactor to proper ter- minal of terminal block are secure. See wiring diagram for more info- mation.

•Ensure that coil on heater relay is energized by ensuring that there is 24 VDC between the gray and blue wires attached to the relay. Remove the black and brown wires from the relay and check for an open circuit across the connection tabs (COM and NO) to which the wires were attached.

•Check for open circuit on thermal cut-out.

(NOTE: Tripping of thermal cut-out can indicate presence of another problem with the unit. Unit should be monitored)

•Remove electrode assembly and clean the probes. If problem is not corrected, replace electrode assembly.

•Make connection to tank secure.

•Make connections to relay secure.

•Make connections secure.

•If the relay coil is energized and there is an open circuit across the connection tabs, replace relay.

•Replace thermal cut-out.
