what kind of front loader do you have? i've got the basic kenmore front loader and it doesn't wash diapers out well at all.
makes me so mad but thankfully my dd is on her way to going on the potty chair all the time. the minishower does help out a ton. but i find that the diapers just have a "smell" to them even when they've been washer for 3 or 4 wash cycles.
