Tank Tube Connections

Tank Assembly

  • 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
