Refer to the wiring diagram attached inside the front trim panel and to the machine data plate for service
size requirements when connecting the dishwasher. Also, refer to Electrical Data, page 12.
To access the controls area, remove the right side panel, remove the front panel and open the control
panel door. The dishwasher electrical service connection can be made through the 1

Dishwasher Without Electric Booster
For single-phase machines, power supply connections are made to terminal blocks. For three-phase
machines connections are made to contactor lugs. The machine must be grounded according to
electrical code(s); a grounding lug is provided in the controls area. Electrical connections for machines
with gas tank heat are made to contactor 1CON in the controls area.
Check Rotation (Three-Phase Machines Only)
Three-phase motors must rotate in the direction of the arrow on
the pump housing. In order to check rotation, remove the bearing
cap to observe the motor shaft (Fig. 15). Close the machine doors
and press the power switch to ON. When the machine is completely
filled, open and close machine doors to verify that the motor shaft
rotates in the clockwise direction.
If the rotation is incorrect, DISCONNECT ELECTRICAL POWER
SUPPLY and interchange any two of the incoming power supply
leads. Reconnect the power supply and verify correct rotation.
Replace the motor bearing cap.
