Motor Fault (Most Common): The machine detects a short circuit in the triac (the motor's electronic switch) or a communication failure between the main control unit and the motor. This can cause the drum to start suddenly or the program to stop immediately to prevent damage.
Faulty Sensors: A malfunctioning water level sensor (pressure switch) may incorrectly report that water is still in the machine when it is empty, or vice versa.
