Water Inlet Mixer
4.15.3 Operating Solenoid Valve (Y5) (Plus Models Only)
With no voltage to Y5, the valve pin (Figure 4-14, Item 5) closes the channel for
cabinet ventilation. The non-softened water then flows behind the valve pin (Figure
4-14, Item 5.1), through an opening in the water channel (Figure 4-14, Item 3.2).
From here it flows upwards to the ball valve (Figure 4-13, Item 6), where a small
proportion of the water passes through a small bypass in the ball valve to the water
reservoir (Figure 4-13, Item 7), for later use during softener reactivation.
Note:
After softener reactivation, the reservoir is filled again by the time the third water
intake has taken place.
The majority of the water, blocked by the ball valve at the water reservoir inlet, flows
through the water channel (Figure 4-13, Item 3.3), to the water mixer outlet and then
to the water softener (Figure 4-13, Item 5). After passing through the water softener,
the now soft water flows via the soft water intake (Figure 4-13, Item 12), back into the
water inlet mixer. It then flows past the non-return device (Figure 4-13, Item 9), into
the sump (Figure 4-13, Item 13).
With voltage applied to Y5, the valve pin is drawn back and a portion of the hard
water flows through the hole into the channel (Figure 4-14, Item 3.1), via the cabinet
ventilation port. This mixing of hard water with the soft water allows the wash water
hardness to be adjusted more precisely.
