Cleaning Head Module
The Error 31 code is triggered when the motherboard loses serial data communication with the vacuum's cleaning subsystem. This is frequently caused by carbon dust ingress from the motor or mechanical vibration causing signal noise at the modular connector pins. Replacing the entire cleaning head module restores the integrity of the communication bus and provides new sensor logic for the brush-speed feedback loop.
