Low Profile Agitator; Water Level Measurement - Fisher & Paykel AQUASMART WL26CW1 Service Supplement Manual

An internal piston within the nozzle moves with the amount of water pressure against it. When the
water pressure is high, more holes in the nozzle are exposed, and the backpressure on the
dispensing valves is less.
When the pressure is low, more backpressure is created, which ensures that either during
detergent dispensing or fabric softener dispensing the dispensing system takes priority.
If the water pressure was very low during dispensing, it is conceivable that no water would enter
the machine via the inlet nozzle until the dispensing has been completed.
Conversely, if the piston was jammed, and the water pressure was high, a high flow rate of water
would go through the dispensing system and may result in water on the floor.

LOW PROFILE AGITATOR

The unique low profile agitator works well in both the High Efficiency and Conventional modes. In
the High Efficiency mode, the clothes have greater contact with the agitator due to the low water
level, and the agitator ensures a high level of clothes turnover.
In the Conventional mode, the clothes are completely submerged in the water and the curving
steep side walls and raised shoulders of the wash plate vanes create enough inward and upward
movement to keep the cloths turning over even when there is reduced contact with the agitator.

WATER LEVEL MEASUREMENT

The AquaSmart™ uses the same pressure sensing system used in the SmartDrive™ and Intuitive
Eco™ machines to determine the water level. The difference with AquaSmart™ is that on both the
Conventional or High Efficiency modes, AquaSmart™ will automatically choose the water level, as
the precise water level for the clothes load is critical to the performance of the wash. The amount
of water used in either mode is unable to be selected or adjusted by the user.
So now there are an infinite number of water levels that AquaSmart™ can choose depending on
the weight and type of the clothes being washed, as opposed to the more traditional 3 or 5 water
levels on previous machines.
