5.2.14 Upper Venturi Assembly - Dismantle

In general practice, the Upper Venturi assembly will not need
to be dismantled except to replace the teflon support washer
after a considerable service life, or perhaps damage to the
left hand thread of the Upper Venturi Bottom from misuse or
cross threading.
5.2.14.1 Stand the Upper Venturi Assembly upside down on
a flat surface or bench top, i.e. with the left hand threaded
end uppermost.
5.2.14.2 Insert two wide bladed screwdrivers between the
under side of the Upper Venturi Bottom flange and the end
face of the Upper Venturi Housing as shown below.
5.2.14.3 Gently exert an even pressure downward with both
screwdrivers to prize the Upper Venturi Bottom from the
Upper Venturi Housing. Refer to the photo in section 5.2.10
which shows both the Upper Venturi Top and the Upper
Venturi Bottom with the teflon support washer dismantled
from the Upper Venturi Housing.

5.2.15 Upper Venturi Assembly - Reassemble

5.2.15.1 Before reassembling, inspect the left hand thread of
the Upper Venturi Bottom for damage, clean and insert into
the lower end of the Upper Venturi Housing.
5.2.15.2 Clean and check for damage to Upper Venturi Top
and teflon support washer.
5.2.15.3 Insert Upper Venturi Top and teflon support washer
into the top end of the Upper Venturi Housing and slowly
rotate to engage the four barb clips located on the Upper
Venturi Bottom.
5.2.15.4 With the four barb
clips located correctly, simply
push the Upper Venturi Bot-
tom with a hand to snap
home and engage the Upper
Venturi Bottom to the Upper
Venturi Top.
5.2.15.5 Check and inspect
to establish that both the Up-
per Venturi Bottom and the
Upper Venturi Top rotate
freely within the Upper Ven-
turi Housing.
5.2.16 Upper Venturi Assembly - Reinstall to
Dishwasher
Reinstallation of the Upper Venturi Assembly to the Upper
Basket Assembly is as follows:
5.2.16.1 From the underside of the Upper Basket Assembly,
insert the Upper Venturi Assembly into the central section of
the Upper Basket where the rectangular opening locates and
retains the Upper Venturi Assembly.
5.2.16.2 Engage the left hand semi circular mount of the
Upper Venturi Housing to the cross bar of the Upper Basket
and snap securely to the cross bar.
5.2.16.3 With the Upper Venturi Assembly pivoting on the
semi circular mount, push the top of the Upper Venturi
Assembly towards the left hand side of the dishwasher to the
full vertical position. The right hand retaining clamp of the
Upper Venturi Housing will engage the cross bar and lock the
Upper Venturi Assembly in place.
5.2.16.4 Reinstall the Upper Spray Arm to the Upper Venturi
Assembly.
NOTE: The thread is left hand.
5.2.17 Upper Basket Rail and Wheel Guides
As the support plate is attached to the vertical chassis rail it
remains captive even if both Wheel Guide Axles are removed
together. To remove the Rail and Wheel Guides proceed as
follows:
5.2.17.1 Remove both front Rail Guide Pegs by compressing
the top sections together and lifting clear from the Rail
Guides as above.
5.2.17.2 Slide the Top Basket out and clear of the Rail
Guides.
5.2.17.3 Remove both rear Rail Guide Pegs from the Rail
Guides and lift clear.
