the main board.
4) If the voltage at 1-2 of CN2 on the main motor is not 220V, replace the
SSR of the PSU and if it is 220V, replace the main motor.
1. Check the voltage at CN101-B15 on the main board
(It should be 0V when the total counter is on. (General status is 24V)
If it is all right, replace the main board.
