If you need to replace the recirculation hose (recirculates water inside the tub) in a Whirlpool Coll-apso washer, you'll be relieved to know that you don't have to remove the inner basket to do so.
This page from the service manual shows where the location of the recirc hose and explains its function:
And Chief Master Appliantologist DADoESTX explains the technique:
The basket *does not* need to be removed. Raise the top, take off the tub ring. Release the tab on top of the recirc tube where it anchors to a slot at top of the outer tub, and pull the tube straight upwards to remove it. Press the replacement tube down into place on the connector nipple/nubbie at bottom of the tub, anchor the tab. Reassemble the tub ring and machine top.
