Dispenser
WM2496H*M
The dispenser works by using
various solenoids to apply water
to different compartments. The
liquid products are dispensed
from a siphon box. As the
appropriate chamber is flooded,
the box fills and the water
flushes the laundry product into
the tub. It is mixed with water
before contacting the laundry to
prevent spotting or damaging
the fabric.
