4.17.3 Regeneration valve
The 2-way regeneration valve directs hard water into the softener
and salty brine from the salt dispenser to the softener (for
regenerating).
• When the valve isn't energized, hard water flows into the
softener to be softened.
• When the valve is energized, water flows into the salt
dispenser to become a salty brine. The valve directs the
brine to the softener to regenerate the beads with sodium
ions. The brine solution is then pumped out.
Coil ratings: 120-127 VAC, 60 Hz, 660 Ω resistance.
4.17.4 Salt capacity
• Fine-grained salt – 1.3 kg
• Coarse-grained salt – 0.9 kg
TIP: Must use granulated softener salt specifically made
for dishwashers, not pellet salt for whole house water
softeners.

4.17.5 Low salt detection
The transmitter LED sends a beam of light into the salt dispenser.
Any salt present will block the beam. When the salt is gone, the
receiver photocell detects the beam and the power module
generates an "Add salt" message on the dishwasher display.
Depending on the coarseness of the salt, there may be leftover
salt and the softener may regenerate after the "Add salt" display
has appeared.
It's not necessary to add water to the salt dispenser the 1
the dishwasher is being run.
TIP: The low salt detector cannot sense salt pellets.
Granulated salt suitable for dishwashers must be used.
