5.2 Dispensing System
Two hoses of different lengths run underneath
the top deck and connect to either the
detergent dispenser or the fabric softener. The
detergent dispenser hose has cream elbows.
The fabric softener hose has grey elbows.
Moulded into the top deck at the valve end are
identification letters (‘D’ for Detergent and ‘S’
for Softener). At the dispenser end are
moulded the words ‘Detergent’ and ‘Softener’.
It is important that the hoses are retained in the
clips around the perimeter of the opening of
the top deck correctly.
5.2.1 Detergent Dispensing
During fill, the detergent valve is also energised. This allows a proportion of the inlet water to flow
into the detergent dispenser.
The flow rate through the detergent valve is dependent on the inlet water pressure, but it is less
than the flow rate of water entering the machine. The valve will remain energised until the water
level reaches 1 inch (25mm), at which point the bowl starts stirring until the desired water level has
been achieved.
The detergent valve can be tested in diagnostics (refer to Section 14).
5.2.2 Fabric Softener Dispensing
The design of the fabric softener is such that it creates a self-siphoning effect. When the motor
control module calls for fabric softener, the fabric softener valve will energise. This allows water to
flow into and through the dispenser mechanism. The initial burst of water starts the siphoning
process. The valve is pulsed on and off for a total of 95 seconds (see table below) to ensure that
all of the fabric softener has dispensed.

Note: The 1
st
off time of 15 seconds is to ‘kick start’ the siphoning process.
If the fabric softener valve was to run continuously, the water would cut a path through the softener
and the bulk of the softener would remain in the dispenser. The maximum level of the softener is
90mls to the ‘Max’ mark. If the softener dispenser was to be filled higher than this mark, the
softener may self-siphon into the machine.
The softener valve can be tested in diagnostics (refer to Section 14).
5.2.3 Inlet Nozzle
In addition to its design, which ensures excellent rinse water distribution, the nozzle shares an
important relationship with the inlet valve assembly and the dispensing system as described
above.
