PRA means there is loss of control voltage 24V supply. Check with a multimeter on the terminal link to the ground terminal if 24V is present in PWR terminal and the internal 24V terminal.

Since I haven't heard from you for the nLP fault try DIY by removing the electronics board clean it look for any ring spot and re- solder then remove all the visible plugs and re-socket in case of any partial contact. For SCF2 fault, check for insulation breakdown on the output side of the inverter towards the motor and if all correct try replacing the filters.
