Over the past month or so I have realized the water level has become lower and lower. I did a test starting with the extra small, then small, medium large, extra large and finally super. With each larger setting more water was provided but the tub was never filled more than just above half way even on super. I have Googled around and it seems the problem is probably the water level switch. Before I order the part I wanted get some verification I'm on the right path.
