Detection of Basket Float Off Point
During fill the basket rotates to ensure that the clothes are evenly saturated with water. Whilst the
tub is filling, the agitator will occasional stop and commence a number of special agitate actions.
During these actions the washer determines if the basket has floated. If it has, the microprocessor
can now determine the correct water level and will continue filling to that level. If the basket has
not floated off, the washer will continue filling and check again later.
Note: The water level at which the basket floats off is not necessarily the same as the final water
level.
Detection of Basket Re-Engagement
After the washer has pumped out the water, the basket will sink down and re-engage onto the drive
spline. To ensure the basket has re-engaged correctly, the washer will carry out a basket re-engage
test. This test consists of a series of short agitate strokes before the spin cycle starts. A sound may
be heard as the basket re-engages.
5.2.3 AUTOMATIC WATER LEVEL SYSTEM
The floating basket is also used to detect correct water level for the clothes load in the washer.
The point at which the basket starts to float is determined by the load size. The greater the load, the
more water is needed before the basket will float. By detecting the point at which the basket floats,
the microprocessor can determine the correct water level.
If the operator has manually chosen a level that is too low for the load, the washer will override that
choice and fill to the correct level. If the operator has chosen a level that is higher than necessary,
the washer will still fill to the operator’s chosen level.
5.2.4 DRAIN PUMP
The drain pump motor is attached directly to the base of the tub. The pump housing is an integral
part of the tub. This eliminates tub to pump hoses and the accompanying seals, clips etc. The
pump is accessible by removing the inspection hatch on the front of the washer. It is also accessible
for cleaning from the top by removing the agitator and basket.
