▪ J. ERROR MODE
When the water heater encounters an error, the display will ash “Er” followed by a numerical code. The water heater shall enter a soft lockout con-
dition if the error is such that it can return to normal operation once the condition relieves itself (overheat conditions, NTC open or shorts, etc.).
The water heater shall enter a hard lockout if the condition indicates something more serious (ame, ignition, condensate line, etc.) To clear a hard
lockout Error Code, press the Power button. The following screen will display when the water heater encounters an error.
