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.
