105 Service Manual 8-23
Fault codes
Fault codes displayed on the LCD screen in “service mode” are in the format N-nn-n. Fault codes displayed on the LCD
screen in “operator mode” have one fewer digit and appear in the format N-nn. The tables in this section show all digits.
The fault priority is assigned based on the fault code value: the higher the number, the higher the fault priority. Only one
fault code is set at one time. If more than one fault occurs at the same time, only the fault with the highest priority is set.
Displaying the service screen
For troubleshooting faults, display the service screen by simultaneously pressing the automatic/manual and current/gas
mode selectors for approximately two (2) seconds. The service screen displays.
