Ldf6920 Check valve motor

My lower arm won’t spin and I’ve taken the sump assembly apart. Looks like the check valve is not spinning from upper to lower spray arms? I rotated it by hand to the lower arms and it now works the lower only. Even when I start washer on upper only setting. I figure it’s the motor since everything is clean and rotates fine. I found part #4681ed3001d as the motor. What else should I change out with it since I will have to remove the dishwasher? Any help would be great.

Hi.

Check the continuity of the motor winding, check if it’ getting the 120VBAC from the control board.
If there is voltage - replace the motor.

It has voyage. I may have got it wet during another repair? I ordered the motor, packing, and a new check valve. That should fix it I think? Thanks for the reply

You are welcome.

Post the results.
