We have a GE GSM1800J00WW dishwasher -or GSM1800JWW
The problem - when we start the machine no water enters the wash bay. In addition I checked the lower spin bar and its does not move.By that I mean it spins freely but when I shut the door, turn it on, off and open the blade hasn’t moved We had a service tech come out and he explained I could do the repair myself and save a few hundred dollars. Dummy that I am I lost the notes on what parts I should be purchasing - IIRC he did not think it costly.
I have been viewing the exploded motor diagrams for the unit but for the life of me I’m stuck.
Any ideas would be great - my wife is none too happy. 
The model number you posted does not look as a valid GE model number. Verify and repost it.

Gene - GSM1800J00WW - sorry 'bout that.
Its a small undercounter unit.
I just replaced the lower swing arm parts but that was obviously not the repair.

Here is a link to the parts page of our dishwasher from your site.
Can you tell me what part I need to order from you ?
thx - rob
