just began doing the same thing. Fills fine on wash cycle, only fills half way or less on rinse then begins to try to agitate. "Power Rinse" setting didn't help, seems that causes a spin cycle after wash where otherwise it only spun after rinse. Used to fill fine without "Power Rinse" selected.
In service 9 months, but we bought it as a test model so it's already out of warranty. (Probably wasn't worth saving $50 for less warranty.)
Any thoughts or suggestions welcome, including suggestions on a decent washer to replace this with!
