Removal Of Pump Hood & Cap (Impeller & Flapper Inspection) - Fisher & Paykel AQUASMART WL37T26CW2 Service Manual

10.18 Removal of Pump Hood & Cap (Impeller & Flapper
Inspection)
(a) Follow procedures for removal of neck ring
(refer to Section 10.14).
(b) Follow procedures for removal of low profile
agitator (refer to Section 10.15).
(c) Remove the inner bowl by lifting the inner
bowl upwards and clear of machine.
Note: If the inner bowl is tight on the shaft,
pressure may need to be placed on the top
of the shaft, while at the same time jiggling
the inner bowl upwards.
(d) Remove the two bolts securing pump cap to
the outer bowl.
Note: It is important that the screw bosses are kept free of grit. If the bosses have any grit,
this can reduce the travel of the screw, which will lead to a poor fit of the cap, which in turn
will cause bypassing (refer to Section 4.9.11). Bypassing can cause water on the floor,
especially if the water dribbles from the recric nozzle on to a spinning bowl.
Grit in the bosses introduces stress in the plastic when the screw is fitted, which can lead
to the cracking of the boss, which may in turn cause leaking.
(d) The impeller and flapper area of the pump
can now be inspected.
Reassembly:
Refit in reverse manner.
Note: There are features on the hood and cap
that make it difficult to fit in the incorrect
position. Ensure the orientation of these parts
is correct before fitting.
