Do I need to order a small gasket when I replace part # 154464101?
The tube will not come with the gasket and you would want to replace the gasket which is part number 154406401.
Please how do you install this part? I am having to replace this part because the threading doesn't match for the spray arm. How do you get to this part looks hidden in the machine.
Answer Helly Nancy,
In order to replace this part you will have to pull the unit out from under cabinet and disconnect the tube from underneath unit. Once disconnected the hose runs up the either the back side or the side of unit. You may have to remove insulation blanket, if yours has one, to take it out.
