the dishwasher frame. (Fig. 3-15)
2. Disconnect the wiring harness connectors
from the drive motor and pump motor
terminals, the soil sensor and the thermistor.
3. Disconnect the drain hose from the drain
hose connector on the pump outlet.
4. Remove the pump motor. (See next

sump up approximately ½ inch.
Push the assembly back and then lift it out.
