3.11.1 Detection of Inner Bowl Float off Point – Bowl Check
During fill the inner bowl will rotate to ensure that the clothes are evenly saturated with water.
When the chosen water level is reached, and before the agitate cycle is started, the machine will
carry out inner bowl float checks (bowl check). The inner bowl will stop and commence a number
of small agitate type actions. During this action the machine determines if the inner bowl has
floated. If it has the machine will determine the required water level and check if the operator has
selected the correct level. If the inner bowl has not floated, the machine will continue filling and
check again later. The water level at which the inner bowl floats is not necessarily the same as the
final water level.
3.11.2 Detection of Inner Bowl Re-Engagement – Bowl Engage
Check
After the water has drained, the inner bowl will sink down and re-engage onto the drive spline. To
ensure the inner bowl has re-engaged correctly, the machine will carry out a bowl re-engage test
sequence (bowl check). Bowl check consists of a series of short agitate type actions before the
spin cycle starts. A sound may be heard as the inner bowl re-engages.
3.11.3 Balance Rings
The inner bowl has 2 balance rings, one at the top, and one at the bottom. These are sealed
compartments half full of water. This water allows the bowl to balance. If one or both of these
rings have lost water then the machine will have out of balance issues and the inner bowl must be
replaced. The easiest way to determine a loss of water is to weigh the bowl on an accurate set of
scales.
Inner Bowl Weights
Compact 7.30kg +/- 225g
Medium 8.37kg +/- 225g
Large 10.48kg +/- 275g
3.12 Agitator
The agitator design differs from conventional designs in that it is made of very flexible plastic that
bends and flexes as the clothes are moved around the bowl. The agitator action is similar to that
of a fish moving through the water, so the side-wards motion is translated to forward thrust. This
is not only more forgiving on the clothes but helps to slowly move the clothes around the bowl in a
toroidal motion, i.e. a vertical circular motion. The fins at the top of the agitator pull the clothes on
