Your details seem to indicate that you have the tech sheet for the washer. I provided the technical troubleshooting for a power supply problem in the image below. You can
unplug the washer
and use that information to check the power supply connections on the machine control board. If the wiring connections to that machine control board are okay and the washer still won't power up, then you will probably need to replace that machine control board. You can order that control board from the
website. The exact part number of the control board for your Kenmore Oasis washer will depend on the model number that you have.
If you need more help, reply with additional details and the full model number of your Kenmore Elite Oasis washer.
If you get to a point where you need to have a service technician repair the washer, you can schedule one through this link:
