Bosch diswasher SMU2046 stalled, not draining

my troubleshooting so far:
normal operation facts:
-the timer terminal 1b goes hi(120v) to turn on the drain motor.
-the normal cycle starts by draining
data:
-there is power and I can hear the timer motor
-the drain motor armature spins freely by hand
-the motor gnd goes to gnd
-120v shows up on timer terminal 1b and on the drain motor terminal connected to it.
puzzle:
-there is another connection to the drain motor with 3 wires connected. Could their status be keeping the motor from running? They go to the solenoid, capacitor and hi-limit. I read 120v there when I turn the dw on.
-it is weird there is no water level switch.
I don’t really want to buy a new drain motor unless I’m sure.
