2.2.6. Wash Pump Assembly and Impeller
The standard wash pump motor is three-phase and can operate clockwise, as well as counter-
clockwise; the
Nylon Lock Nut used to hold the impeller in place (See Figure 2.2.6), is very
important. When servicing the Wash Pump Assembly and replacing the seals, make sure it is
secured properly; otherwise, if the motor turns the wrong direction, the impeller may spin-off the
motor shaft causing damage to the impeller.
Note: ALWAYS CHECK THAT THE DIRECTION OF THE MOTOR ROTATION IS CLOCKWISE,
WHEN REINSTALLING THE WASH PUMP. IF THE MOTOR IS TURNING COUNTER-
CLOCKWISE, EXCHANGE L1 AND L3 WIRES ON MAIN CONTACTOR
Figure 2.2.6
Note: The Nylon Lock Nut indicated by the arrow in
Figure 2.2.6
must be removed before
attempting to remove the water pump impeller.
