How to reset the control from Lockout Conditions:
The following procedure is for service and installation personnel only. Resetting lockout conditions without correcting
the malfunction can result in a hazardous condition.
If an error code is displayed (except for #4, low flame sense current), the water heater will be in a "lockout condition" with
the water heater display showing the error code number and "Service Needed" in the status section of the display window.
Error codes 62 (maximum number of retries detected) and 63 (maximum number if ignition recycles detected) are "Soft
Lockouts" in which the control can be reset in the "User Mode" by pressing the lower right button under "Lockout Reset"
shown in the lower right portion of the display. The control will also go through 3 attempts to relight the burners every hour
in the soft lockout condition.
All other error codes will put the water heater into a "Hard Lockout" condition, in which the water heater will not operate and
cannot be reset in the "User Mode". To reset a hard lockout, first enter the "Service Mode" described earlier by pressing
both the "Temperature Up" and "Select Buttons" at the same time for 3 seconds. Then press the lower right button under
"Lockout Reset" in the water heater display and hold for 3 seconds.
