Error 14

Indications

The self-diagnostic test found a problem

with the Flammable Vapor Sensor. (This is

not a flammable vapor event. It may be

caused by disconnecting the FV sensor

Molex, or the FV sensor itself. This

includes both short and open electrical

connections.)

Troubleshooting

1. Check all FV sensor wiring harness connections; and the connections to the back of the

sensor.

2. Cycle power to the water heater off for 10 seconds and then back on.

3. If no wiring problems are found, the Flammable Vapor Sensor must be checked.

a. Disconnect the FV sensor Molex and measure the resistance of the sensor

between the two black wires 2 and 3. If the resistance is less than 9k OHMS or

greater than 45k OHMS, then replace the sensor.

b. If the FV sensor is between 9K and 45K and the code will not clear by recycling

power, replace the INTELLI-VENT control.
