No partial drain.........................
on any SQ residential washer. I have the AWN542, and I am very satisfied with it. After four years of use, I had the belt replaced and the brakes lubed, my washer took a beating in my 20 degree basement this winter. Sorry about the grease on your machine, hope you get it out, but it is not a mechanical issue, so that is good, but I understand your frustration. These are well built washers, and they will last a long time...longer than any traditional brand front loader out there today!! Top or Front loader the only way to go today for quality build, warranty, service, and performance is with a Speed Queen.

PS I bought my mother a set as well, and she loves it!
ALSO TRY SEVERAL HOT WASHES WITH PINE-SOL, THAT SHOULD GET ALL THE GREASE INSIDE AND OUT OF YOUR TUB!
