4.11 Neck Ring
The neck ring incorporates wells used for the
fabric, detergent and bleach dispensing.
The neck ring is clipped in place to the outer
bowl. It also restrains the re-circulating nozzle.
It is important that the neck ring is secured
correctly to the outer bowl, as it affects bump
detect (out of balance detection). The bowl
assembly may experience more movement,
which could lead to cabinet damage.
Dynaflex straps are located at four points on the
neck ring and connect to lugs on each of the
suspension rods.
The straps serve two purposes:
1. To limit radial bowl motion during agitation.
2. As the straps stabilise the bowl, it also
improves wash performance.
If one or more straps break, this can cause an
increase in out of balance activity, which again
may lead to cabinet damage and noise from
loose straps, always replace the straps never
refit them.
For a detailed explanation of Bump Detect,
(refer to Section
4.3).
4.12 Inner Basket and Outer Tub
The outer tub is the assembly to which all the motor, pump system, suspension rods, etc are
mounted. Within the outer tub is the inner basket and the agitator. During spin, the agitator and
inner basket have to be coupled together and turn as a single unit. In agitate; the agitator and
inner basket are free to rotate independently.
The inner basket is free to move in a vertical direction. The position of the inner basket is
determined by the water level. At the base of the inner basket is a flotation chamber consisting of
a number of individual cells. When the machine is filling with water, the pressure on the air in
these cells increases as the water level rises until eventually the inner basket floats upwards and
disengages the driven spline from the drive spline. This action frees the agitator from the inner
basket and allows it to move freely in both directions.
When the water is draining, the pressure on the air trapped in the cells of the flotation chamber
decreases allowing the inner basket to settle back down onto the drive spline and re-engage the
driven spline, thus allowing the agitator and inner basket to turn as one unit. The floating basket is
also used to detect if the correct water level for the size of the clothes load.
The point at which the basket starts to float is determined by the water level and the size of the
load. The greater the load, the more water is needed before the inner basket will float. By
detecting the point at which the basket floats, the machine can determine whether the correct
water level for the particular clothes load has been reached
