GE Appliances GDT645SYNFS how to fill and adjust the rinse agent
About once a month, and when spots or poor drying appear. The indicator window does not light up.
Steps
- Open the dishwasher door fully and open the rinse agent dispenser door.
- Add rinse agent slowly until the cup is full, pausing to let it settle.
- Wipe up any spill with a damp cloth so it does not foam.
- To change the dose, turn the adjuster clockwise for more rinse agent (against drops and hard-water spots) or counterclockwise for less (against foaming).
- Close the dispenser door.
