4.1.15 Terminal box
Since 9/23/02, all dishwashers have terminal boxes ("junction
boxes" / "J-boxes") with covers. Boxes were upgraded to a larger
style (with conduit exits) on 3/18/03.
NOTE: Old terminal boxes built before 9/22/02 met UL standards
– toe kicks were approved as terminal box covers. There's no
need to change out old terminal boxes. Covers can't be added to
these boxes since they don't have cover screw holes.
4.1.16 Drain hose
Dishwashers UC/48 and later use a two-hose (internal / external)
drain hose system. A customer (external) drain hose (during
installation) is connected to the internal drain hose, with the 90º
elbow pointing toward the customer drain. The external drain
hose connects directly to the customer drain system without an
adapter.

4.1.17 Dispenser
The dispenser is located near the top of the inner door and
reliably dispenses detergent and rinse-aid.
During each wash program, the wax motor opens twice, once to
dispense detergent and again to dispense rinse-aid. The wax
motor opens the same -- linkages open the detergent door &
operate the rinse-aid dosage plunger. Dispensers can have reed
switches or optical rinse-aid sensors.
m
CAUTION: Inner door edges are sharp! Cover door edges
and remove dispenser carefully.
