The Drain Check Valve is located inside the sump
bottom. To access, remove both filters and pull
the assembly from inside the sump.
Also located on the top side of the sump are the
diverter components. The bottom of the diverter
is molded into the sump. A check ball or two
port diverter and a pressure diverter are used in
these models. The pressure diverter may use
three or four ports controlling reversing spray arm
on some models and silverware wash on some
models. Full details on both diverters is found in
the circulation section of this service guide.
Components on the bottom of the sump include
a pressure switch, turbidity sensor, drain pump,
circulation pump and some models have a
diverter location switch.
The sump module is front serviceable with the
dishwasher remaining in the installed location
by removing the door for easier access. This
section of the guide only covers the sump
removal. Components and diagnostics of the
sump module may be found in the
