4.13 Flow Meter – Operation
The incoming water turns an impeller that contains a magnet located in the flow
meter axle. As the axle rotates (impeller turns), an external reed switch is switched
on or off by the effect of the magnet. The electronic monitors the number of pulses to
determine the volume of incoming water. For each 0.26 gallons (1 liter) of water,
approximately 200 pulses should be registered.

Water Intake

If the water pressure is low, the electronic can be programmed to increase the
allotted intake duration from 2 minutes to up to 4 minutes.
For further information, refer to Section 6 ("Fault Diagnosis").

Water Mixing

4.15.1

External Flow Meter

Refer to Figure 4-10.
The supply water flows into the WaterProof System (Item 10), to the water intake
assembly, where it passes a non-return valve (Item 6). The non-return valve
prevents a reflux of water from the machine into the supply should a vacuum develop
in the system.
The water path is then divided at the bypass (Item 5), and up to 5% of the water
flows directly into the cabinet without passing through the water softener. Depending
on the water hardness selector setting (Item 4), a proportion of the water flows
directly into the cabinet via the cabinet ventilation (Item 9). The remaining water fills
the reservoir in the water inlet (Item 7) for later reactivation of the softener. When the
reservoir is full, water flows through the ion exchanger (Item 14) and the intake
opening in the sump (Item 2) to enter the cabinet.
