Why does my AUMA SAEx 16.2 display 'Phase fault'?
- EErica SchwartzJul 25, 2025
The 'Phase fault' error on your AUMA Controller indicates that one phase of the power supply is missing, meaning the controls are not receiving mains voltage. To resolve this, test and connect all phases of the power supply.
