For models with Honeywell Integrated Control

System w/ Direct Spark Ignition

Serial Numbers including and AFTER GB13006174 and ALL EFR models

Lockout Conditions

The system will go into lock out mode for the following reasons:

1.ERROR CODE 62 or 63

Control board will go into “Soft Lockout” if the main burner cannot be lit or fails to prove flame after 3 ignition trials. The water heater display indicates a lockout condition by showing an error code number (62 or 63) with “Service Needed” in the control display window. Refer to error codes in the diagnostic section of this Service Manual. In a “Soft Lockout” condition, the control will wait for 60 minutes and then make 3 more attempts to light the main burners. Soft lockout reset is accomplished by depressing the lower right button under “Reset” for 3 seconds.

2.ERROR CODE 65

If the top of the tank should exceed 200°F, then the high limit control will shut off the burner and the water heater will go into a “Hard Lockout”. Error code 65 will be shown in the water heater display. The control can only be reset in the “Service Mode”, which is detailed in the “Troubleshooting” section of this Service Manual.

3.ERROR CODE 29

If the exhaust terminal becomes blocked or the condensate elbow fails to drain condensate, the normally closed exhaust pressure switch will open, the gas valve closes, and error code 29 will appear on the control display. When the condition is corrected, the error code will disappear and the water heater will resume normal operation. No resetting of the control display is needed for the pressure switch error code.

4.ERROR CODE 26

If the vent safety switch located near the exhaust pressure switch should open, the gas valve will close, the blower will post-purge and error code 26 will appear on the display. The lockout condition will reset once the problem is corrected and the switch reset. Refer to “Vent Safety Switch Testing and Replacement” in this Service Manual.
