removed, you can look into the base assembly of
the dishwasher and check several points before
requiring the removal of the unit for service.
In the images below, you can see the sump
assembly (1),12-Pin disconnect pin (2), and the rear
leveling leg adjustment screw (3). In order to access
and service the remaining components, the base
cover will need to be removed to gain access. This
includes the drain motor, circulation motor, control
board, flow-through water heater, wash temp
sensor, water valve, front levelers, and the rear
leveler.
