K2018 Detergent Tank 72oz
U-shaped tube has 2 small holes in its side. One of these holes is at the bottom of the “U”, and the other is near one end of the tube.
The end of the tube that does have a hole in the side is attached to the tank lid with the vent tube plug (small thumb tack shaped piece).
The end of the tube that does not have a hole in the side is inserted through the hole in the lid of the detergent tank and protrudes from the top of the lid approximately 1 inch.
Your Dishmaster will not function properly if tubes are not assembled correctly. Tube-to-tube connections must have minimum overlap as shown and must be airtight.
Apply a small amount of liquid detergent to the inner tube
Heat the end of the soft outer tube in hot (not boiling) water to make the tube more pliable
Push the two tubes together with at least the minimum overlap as shown
The outer tube will shrink and the detergent will dry to make a 'glued' but not permanent connection
Attach the corner pads per the illustration.
