Water Intake Monitoring - Water Control System (WCS)
Water intake monitoring will register a shut-off faucet, too-low water pressure,
or a seal problem (such as a missing lint filter).
If a fault occurs, the program is stopped and the fault message Water intake
fault is displayed.
Water intake fault is issued under the following conditions:
if after 5 seconds of water intake the flow meter (B3/4) does not register
a signal,
if after 150 seconds of water intake the imbalance sensor (ADS) does
not register an increase of at least 0.3" wc,
if the flow meter (B3/4) registers 4 gallons (15 liters) of water intake and
the water pressure as measured by the imbalance sensor (ADS) did not
increase to at least 0.8" wc,
or if the water volume in one block rises above a critical threshold.
Hot water only: When the Hot water intake option is selected, the fault is
not saved and the program that is running is continued with cold water.

Water Overflow Monitoring
If the overflow level of 10" wc is reached, the drain pump (M8) runs until the
level drops by 3" down to 7" wc.
2.6
Flow Meter (B3/4)
The flow meter is integrated into the water path control unit and generates
impulses depending on the water flow.
Based on these impulses, the electronic calculates the amount of water that
has run into the suds container.
Advantages:
The flow meter registers the amounts of water flowing in more accurately,
compared to previous systems without this sensor.
The imbalance sensor (ADS) monitors the function of the flow meter.
During a malfunction or total failure of the flow meter, the water intake is
controlled via level-controlled fill.
2.7
Water Path Control Unit and Motor (M24)
Activation by electrical motor. Measurements are taken via a slip contact
in the water path control unit.
Water path control unit with an additional fifth position for bleach.
