11.2 Fault Codes
NF*
The dispenser records all errors, or faults, that occur. A history of these faults can be found in the FAULT CODE HISTORY
menu located in the SERVICE MENU. Each error has a three digit number associated with it. The first two digits are the
error number and the third digit is the barrel number with the error. If the third digit is a 0 (zero) then the error is a common
error to all barrels or it's a dispenser error.
