Siemens EQ700 EQ9 board removal and repair Grinder rotates continuously when the machine on power

Part 2. In the video, the circuit board is removed and repaired. The EQ700 doesn't have a proper power switch that completely cuts off the power. As a result, the MOSFET in question is constantly receiving 280V DC. During a voltage spike in the household electrical system—or possibly due to age-related wear—the MOSFET burned out and became continuity-free. As a result, the grinder started because it received power and ran until the motor overheated and the thermal fuse tripped.

Therefore, my urgent advice: Never bypass the thermal fuses of such devices! This could lead to a fire in an emergency.
