You are missing several digits at the end of your model number.
I think the attached is the correct wiring diagram.
I would check the start circuit.
Set the timer to mid cycle timed dry.
Unplug the unit.
Attach one meter lead to the L1 prong on the line cord and leave it there.
Use you most sensitive meter scale. Also short the meter leads together before starting so you can see if the meter has a zero offset.
Now work your way back through the start circuit.
L1 to BK and BU on the timer should be 0 ohms.
Blue/black or may be just blue on the start switch should be 0 ohms.
Light blue on the start switch should be 0 ohms with the switch pressed.
Keep the switch pressed,
Both sides of the thermal fuse should be 0 ohms.
4M at the motor's centrifugal switch should be 0 ohms.
5M (white) at the motor should be about 1.5 ohms.
Timer contacts for Timer Switch 4 (W and T) should both be 1.5 ohms.
Both sides of the door switch should be 1.5 ohms.
Neutral at the terminal strip and line cord prong should be 1.5 ohms.
There that is the start circuit checked.
With luck you will find the problem part/connection.
