How do I properly level the WAW285H1 washing machine?

Install the washer on a solid, level surface and adjust the feet as needed, starting with all feet turned all the way in and extending them only as much as necessary. Use a bubble level on top of the washer to check that it is level side to side and front to rear, then press down on each corner to confirm there is no wobble. Once level, use a 17mm wrench to tighten the locknuts against the washer bottom to lock each foot in place. (Page 17)
