Hi @sashadkosloff
If you mean 796.41272211 then here's a previous answer regarding the model on ifixit, that may help.

It's not quite the same problem, but buzzing sound would indicate problems with the power being supplied to the solenoid and that comes from the control board.
Perhaps check the control board for any obvious component damage. If there is then I can't find a schematic for the board and it is no longer being made by the manufacturer (LG makes the washer on behalf of Kenmore so it's all LG parts)
If the board is faulty there are still a few suppliers that have the board if you wish to replace it. Search online for [https://www.google.com/search?client=firefox-b-d&q=EBR74798611|EBR74798611] (examples only) to find suppliers that suit you best.
