Electrolux Washer - 31 Error Code
The washer detected a communication fault between control boards.
Meaning
The washer detected a communication fault between control boards.
Error 31 indicates that the washer’s main control board and secondary control modules (such as the inverter or I/O board) are not communicating correctly. Commercial Electrolux washers use a serial communication bus to coordinate motor control, heating, water level, and safety systems. If communication is lost or corrupted, the washer halts operation to prevent unsafe behavior.
