I did a breakdown of the mvwb300wq1 model . This is what I am dealing with. 1. Got the F51 message that led the whole procedure. 2 removed basket . 3. Took motor assembly apart.
Checked for continuity on rps and. Motor driver, all was good. 4 The large nut at the bottom of shaft was totally lose and just there doing nothing. 5 Then I discovered that the basket was not rotating as it should. It would rotate easily for a short bit and then turn with much difficulty. The elctronics appear to be okay.
