* Codes listed above with 1 asterisk… these codes are confirmed necessary to reset specific fault codes (read below for a list of faults which definitely require resetting from the NVM.

** Codes listed with 2 asterisks… it is unclear in the manual if these actually require resetting from the NVM Read / Write or not. Some of them will likely reset by turning the power off and back on. If a machine seems “locked up” because of one of the related faults, it’s worth looking at the NVM codes to see if any of them are no longer showing a value of “0” as they should.

Fault Codes which require resetting from NVM Read / Write:

Remember to always solve the cause of the fault before resetting them in memory.
