18. Rinse Agent Dispenser
The rinse agent dispenser on dishwashers automatically inject a small amount of liquid rinse agent into the
dishwasher during the final rinse cycle. This wetting solution acts to break down the surface tension of the water,
minimizing the formation of spots and streaks on dishes and glasses.
The dispenser tank holds about one month supply of agent. During the final rinse the timer activates a solenoid
on the dispenser assembly. The solenoid pulls up a rubber tipped valve pin allowing a small amount of agent to
be released into the tank where it is distributed by the action of the water.
