Motor won't start for self serve bay

[K&M Carwash]

At one of my bay's, the motor will not start in the soap or rinse position, but it will start in the wax position. I switched out the timer and the rotary switch on the coin box, but it did not correct the problem. I am looking for help to correct this problem. Anybody have any ideas. I would appreciate it.
Thanks.

It sounds like that the jumper wire from terminal 21 to the soap and rinse terminals has come off or has lost continuity. With the bay turned on jumper from 21 to the terminal for soap and for rinse on the 20's stack and the pump should come on.

If it's GinSan equipment, your logic control may be bad.

Open the control box over the pump, take a picture and post it here.

Actually, the it would not be the GS27D logic control if one of the high pressure functions comes on but two others do not. The logic control just provides a delay for the motor contactor so that if someone flips through functions the contactor is not being "pulsed".

Most likely it is the jumper on the rotary switch.

I'd cut the ends of the wire connection and redo. Maybe one of the ends went bad.
