Smell from washer sounds like water still in washer

Neptune washers are the only front loaders that have a counter balance system and they do have water in them to do this. water sound is normal.
when you are having an odor, it is from using the wrong soap or too much of the right soap.
you need to be using "HE" type soap and dont use too much. what you are smelling is soap residues that are not getting rinsed out from the unit.
they do make a special cleaning tablet called "affresh" and it is designed to clean out these residues.
also your washer will have a " brush" type device around the front of outertub where the inner tub meet.
it is between the tubs and will collect debris and can look nasty when dirty.
clean all you can see and then try to run 1 cup bleach thru unit if you cant find affresh tablets. at lowes or sears.
then make sure you use HE type soap next time to prevent build up and odors.
