4.6.1 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
6.1.2 for LCD models, or Section
7.2 for LED models).
4.6.2 Bleach Dispensing
The design of the bleach dispenser is such that it creates a self-siphoning effect. When the motor
control module calls for bleach ¾ of the way through the wash portion of the cycle, the bleach
valve will energise. This allows water to flow into and through the dispenser mechanism. The
valve is pulsed on and off for a total of 95 seconds (see table below) to ensure that all of the
bleach has dispensed.

off time of 15 seconds is to ‘kick start’ the siphoning process.
If the bleach valve was to run continuously, the water would cut a path through the bleach and the
bulk of the bleach would remain in the dispenser. The maximum level of the bleach is 120mls to
the ‘Max’ mark. If the bleach dispenser was to be filled higher than this mark, the bleach may self-
siphon into the machine.
The bleach valve can be tested in diagnostics (refer to Section
6.1.2 for LCD models, or Section
7.2 for LED models).
4.6.3 Fabric Softener Dispensing
The design of the softener dispenser is such that it creates a self-siphoning effect. When the
motor control module calls for softener at the beginning of the deep rinse cycle, the softener valve
will energise. This allows water to flow into and through the dispenser mechanism. The valve is
pulsed on and off for a total of 95 seconds (see table below) to ensure that all of the bleach has
dispensed.

70mls to the ‘Max’ mark. If the softener dispenser was to be filled higher than this mark, the
softener may self-siphon into the machine.
