Unable to Register Washer/Dryer/Refrigerator

[userjy3l4iLtKs]

I've tried to registry my washer, dryer, and refrigerator using these 3 endpoints below and gotten the same error each time saying "This is not a valid Model". This happens after inputting the Serial Number and selecting "Verify" which then pulls up the correct Model number I have on my machine. Then when I select "Confirm" I get the error message.

My product's model numbers are:

RF28R6201SR/AA

DVE52M7750V/A3

WA52M7750AV/A4

These match the model numbers that are loaded after I input the serial number into the URLs above. They also are on my machines. 

Please help with registration.
