INTELLI-VENT™ TROUBLESHOOTING GUIDE

Error Codes & Diagnostics

The Intelli-Vent™ control will not have any LED lights illuminated during normal operation

(sleep mode) for the life of the water heater. When an LED is illuminated, it draws

attention to the water heater and the need to have it serviced.

There are 15 different diagnostic error codes the Intelli-Vent™ control is capable of

displaying by illuminating various combinations of LED lights. All 15 are covered in the

troubleshooting guide that follows.

The same combination of LED lights are used for error codes on residential and

commercial controls though the way they are displayed differs slightly:

Residential controls display error codes via constant illumination of the LED lights.

Commercial controls display error codes by flashing the LED lights on and off.

Important Service/Installation Notes:

1 Always turn power off for 10 to 20 seconds and then back on again to clear an

error code before replacing an Intelli-Vent™ control.

2 When installing the water heater or a replacement Intelli-Vent™ control, do not use

the control face as a handle to move the water heater or turn (thread) the control.

3 When installing a replacement control do no pinch, pull, or cut exposed wires.

Troubleshooting Guide Notes:

• Residential error code displays are shown on the left and commercial on the right

for all 15 error codes that follow.

• LEDs filled in black indicate an Illuminated LED.

ERROR CODE 1 - NO EARTH GROUND

Inadequate or no earth ground sensed by Intelli-Vent™ control.

Check / Repair:

• Insure the wall outlet is properly grounded.

• Insure all ground connections on the water heater are secure.

• Insure ground path wires (if so equipped) between wiring boxes and heater jacket

are properly secured.

• Insure the ground (green) wire in the power cord is continuous with an ohm meter.
