COMPONENTS
Dispenser
The dispenser, located in the middle of the inner door, reliably dispenses
detergent and rinse-aid.
During each wash program, the dispenser operates twice, once to dispense
detergent and again to dispense rinse-aid. HINT: The amount of rinse-aid
dispensed is changed on the control panel, not at the dispenser.
Coil
Actuator
The coil moves the detergent cover actuator and is powered by 160 VDC pulses
from the control. When the coil is switched on, the actuator moves to the left
(see the drawing on the right). The actuator is connected by a plastic lever to
the detergent cover release lever.
detergent cover opens.
A "latching mechanism" between the coil actuator and rinse-aid valve prevents
rinse aid from being dispensed when the coil is initially actuated. After the
detergent cover has opened, the mechanism changes position like a ballpoint
pen (when it's clicked), preventing the detergent cover from moving and
allowing the rinse-aid pump to dispense rinse aid.
Each 160 VDC control pulse dispenses 1 ml of rinse aid. The total amount of
rinse-aid depends on the dispenser setting. A vent equalizes the pressure in
the dispenser so rinse-aid is dispensed accurately.
The actuator is "reset" when the detergent door is opened so the detergent
cover opens first the next time the coil is activated.
Detergent tablets dissolve more slowly if there's moisture left in the detergent
dispenser. Two plastic ribs in the detergent cup prevent detergent tablets from
"sticking" to the cup.
