Detergent Dispenser - GE DDT595SxJ0 Series Technical Service Manual

Detergent Dispenser

The detergent module is Solenoid operated, using
13.5 VDC (from the UI) to activate the solenoid.
Some models have a rinse agent dispenser. The
dispenser holds 3.5 oz. (100 ml) of rinse agent. Under
normal conditions, this will last approximately one
month.
The module receives 13.5 VDC for 1 second to
activate the detergent cup. To activate the rinse
aid, the module receives 13.5 VDC for a period of 15
seconds.
A sensor is used to detect rinse aid level and advise
the consumer when the level is low. The rinse aid
sensor is covered on the next page.
