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.

The machine was left unattended in an office overnight—no one was there. Therefore, my urgent advice: Never bypass the thermal fuses of such devices! This could lead to a fire in an emergency.
