Removing the Impeller from the Wash Motor
The impeller is attached to the wash motor and can
be removed once the wash motor is removed from
the pump base.

into the back of the wash motor to hold the
armature of the motor from turning while un-
screwing the impeller clockwise.
(Fig. 3-23)
Take care not to scratch or nick the motor
windings.
To Remove the Volute
