Aqua Control (certain models only)
The Aqua Control system is a sensor located in contact with the base frame. The sensor detects water
leaks inside the machine (not only during normal operation, but also when the unit is off and plugged in) and
starts the drain pump if a leak occurs.

Control
Besides supporting the various components on the appliance (drain pump, recirculation pump, shock
absorbers, etc.), the base frame is designed to be a container that collects any water leaks that may occur
(from the drum, from a tube or pipe, etc.). These leaks are directed into an area where a float is installed.
When this float is raised by water, it actuates a microswitch that starts the drain pump. When the switch is
tripped, an
ALARM
is also generated (if the machine is switched on).
Important
: When replacing the drain pump or tube,
position the tube so that it does not interfere with the float.
