Product review (5 stars): Order this if in doubt!
Don't get confused with which bellow/boot you need. I work on appliances and opted for this boot because I didn't take note of which the customer needed. I did; however, realize that I could cut out the sealed portion and use it effectively.

The seal sits over a nipple in the boot that allows water in newer (updated) models to drain from the boot area back into the drain pump. If you're purchasing new, take off the spring (Tool recommended for women and weak mean ;) ) and check for the black hose on the very bottom of the boot. If there, order the correct part # (MDS33059402). If not, order this

If in doubt, order this and modify accordingly. Happy repairing
