At twenty-five guides this is the largest Bosch hub, and it sorts into three families. Water movement: a washer that will not drain, the drain pump, the inlet valve, the mains filter and the pressure switch that tells the control how full the tub is. Motion and vibration: shock absorbers, suspension springs, the drive belt, carbon brushes, the drive motor, and safely moving the machine. Control and door: the control module, the selector switch, the door lock and the door interlock.
Vibration is where reading the right guide saves the most work. A machine that walks across the floor is usually asking about levelling, transit hardware and worn shocks or springs, not about the drum, and the troubleshooting guide separates those before any part is bought. Carbon brushes are treated as a wear item with a visible service limit rather than a failure. Drainage complaints follow the water: filter, then hose, then the pump itself, which is the most expensive of the three.
The stopping points on this machine are electrical and mechanical in equal measure. A 2000 watt heating element and the mains filter both sit at line voltage inside the cabinet. The door interlock is the other one, and the rule there is simple: it is a part to replace, never a part to defeat, because it is what keeps the drum from turning with the door open.
