Operation

4.3.1 Sensors
4.3.1.1 Water / load sensor
Using the pressure switch, washers determine at predetermined
st
points during the 1 fill if they need more water. Once the laundry has
absorbed all the water it can, the water level rises, causing the
pressure (in the pressure chamber) to increase to the level the
pressure switch doesn't provide more water.
This water saving feature is needed due to different laundry water
absorption levels and load sizes.
4.3.1.2 Digital temperature sensor
Along with the washer control, the NTC monitors the water
temperature and controls how long the heating element is on, insuring
proper temperatures.
4.3.1.3 Suds sensor
Using the pressure switch and motor speed, washers determine
during the start of the 1st rinse if there are excessive suds and add 2
rinses (if necessary).
With oversudsing (or suds lock) where washers can't remove the
excessive sudsing, washers won't spin and laundry will be wet.

4.3.1.4 Unbalanced load sensor
During final spin, washers monitor motor speed changes to determine
if loads are unbalanced. If so, washers stop, adjust loads and reduce
spin speeds up to 15 times to allow wash cycles to finish.
