What is purpose of the "extension nozzle", #AP4028923 and where does it actually go? It fell out while cleaning the dispenser.
Answer Hello Lemax,
The extension nozzle was only used before series 87, (serial numbers beginning with the digits 87 or lower), and it installs between the front dispenser nipple and the shower hose. The shower hose is the hose that fits onto the top middle of the outer tub. Its' purpose was to aerate the water and give enough water flow resistance to make more water go through the dispenser for the detergent "wash" effect, (washing the excess detergent into the tub).
