Unplug or disconnect power to the machine and access the electronic control board. Remove the screws in the back of the top panel, then lift the back of the top panel and slide back to remove.
The electronic control board is located on the left side near the top. It's very common for that part to fail. Look on the back side for a burned or scorched mark near the relays.
Measure the resistance between P1-3 and P1-4. If the resistance is between 1-6 ohms, replace the control board. If not check the belt switch for continuity.
Check the motor windings at the motor switch. Disconnect the motor connector. Measure the run/main windings between the blue wire in back and the white/orange wire (2.4-3.6 Ohms). Measure the start windings between the blue wire in back and the Violette wire (2.4-3.8 Ohms).
Lift the idler pulley up and measure between the two blue wires to check the belt switch.
