still no spin- diagnostic help?

below is a link to the tech sheet for my washer:

Can I put this machine in a diagnostic mode and if so how?

Reason I ask is that my machine still won’t spin after having replaced door lock wax motor (and checked that it does close contact points internally), replaced the pump, and replaced the speed control board.

Washer goes through cycles normally in every aspect except spin. When it should spin, it just sits there with the pump running and does some slow speed both directions action.

Any help would be appreciated
