Turn on water dispenser - Bosch B22CS80SNS (220 cu ft) Side by Side Refrigerator

I assume you are referring to the water dispenser on your GE refrigerator. To turn off the water dispenser, you can either: Press and hold the "Lock" button on the control panel until the water dispenser display turns off. This will lock all the functions of the control panel, including the water dispenser. Locate the water shut-off valve behind the refrigerator and turn it off. This will shut off the water supply to the refrigerator and disable the water dispenser. Note: If you are trying to turn off the ice dispenser, the process may vary depending on the model of your refrigerator. Some models have a separate on/off switch for the ice dispenser, while others do not allow you to turn off the ice dispenser without turning off the entire refrigerator. Please consult your owner's manual for specific instructions.

How to Set the Temperature on a Primo Water Dispenser

1. Move the Primo water dispenser away from the wall, being careful not to tip or spill the water bottle.
2. Locate the flat, brass-colored screw on the back of the water dispenser.
3. Turn the screw slightly clockwise for colder water or counterclockwise for warmer water. ...
4. Check the temperature of the water.

What do you mean "with no one around"? It turns water on spontaneously? does it turn off again? Is it making ice and dispensing it correctly? Don't you love figuring this stuff out? :)

The water for the dispenser comes from a reservoir in the fresh food section behind the crisper drawers. So the only way to make the water colder is to turn down the temperature in the fresh food side of your refrigerator. The water dispenser is designed to dispense chilled water, not ice water. hope this helps.

For the FAV6800A or FAV9800A:

If you have no water flow to the Softener dispenser or Bleach dispenser see if you can turn the dispenser valves on Service Mode and verify water flow to the reservoirs.
Enter Service Mode (page 14 of the Service manual) by Pressing Enviro Plus and Spin Only keys (simultaneously) for three seconds or until the console beeps.

Now go to page 16 to Service Manual and enter Board Output Test by pressing the Delicates key. This will lock the lid. Now press the Wrinkle Control Key Pad on the console. The Control Board will send 120VAC to the Fabric Softener dispenser water valve. Did you hear the solenoid hum? If so we will now need to turn on the Cold Water Inlet Valve and see if water flows to the dispenser.

Now press the Spin Only key this will turn on the Cold Water inlet valve after 5 seconds press the Off key. The washer will unlock. Check to see if water did flow to the fabric dispenser reservoir. If you heard the Fabric dispenser valve hum then most likely 120VAC was applied to the solenoid. If water did not flow then the Fabric dispenser valve is stuck closed if you heard it hum.

The Bleach/Fabric dispenser water valve is an assembly and is not repairable you have to replace.

Final technical troubleshooting as a technical owner of the machine would be to take my DVM and verify 120VAC from the Control Board to the Fabric dispenser solenoid.
See page 36 lower left hand corner is the Bleach/Softener dispenser valve.
