Forallthemodels this manual mentioned

Process of water inlet (indicated by magenta route)
Process of cycle washing (indicated by blue route)
Process of regeneration (indicated by green route)
In this process, regeneration water route is cut off, main water route is open. The water in the main water
route is softened when pass through the softener, and then enter in the tub. During this phase, some of inlet
water will be stored in the air breaker to be regenerating water.
Cycle washing action is driven by washing pump motor. Water can obtain the power during it passing through
the working washing pump, then be pumped into spray arm, pass from spray arm nozzles, over the dishes,
into sump ,where connect to washing pump, and to get in the next water cycle.
Regeneration valve is open, the regenerating water dissolve salt in the salt chamber of softener, and then
enter in the resin tank to reactivate the resin.
