106.54563300 Water dispenser not shutting off

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.

Your unit has a inlet valve that the supply of water flows to..This valve splits between allowing water to either the dispenser or the icemaker..This valve may be sticking open allowing water to keep flowing to dispenser..Google Model # w/problem to find location and part#..or call your local appliance repair company

Sounds like the ice maker is not shutting off like it should.

If your water dispenser will not shut off then it is either the dispenser microswitch or the water inlet valve in the back of the refrigerator.

Check the solenoid valve is not stuck open. It lets water in, pushing cold water out, and if stuck will not shut off.. It may even have a broken spring, but that is quite unusual

This could be caused by a malfunctioning fill valve. Here is the one it calls for. Valve is in back, it is what water supply line connects to.

Are you saying water is dripping out the ice dispenser or the water dispenser, a water filter would have nothing to do with this, it only filters water, it does not pump water nor does it shut it off. If water
is dripping from the ice dispenser, it is because the rubber gasket
is bad on the flap that seals after ice is dispensed. If water is dripping
from the water dispenser, it is the shut off for the water, you can put a glass under it and push for water a few times,on and off and see if this makes it stop, if not you would need to have this replaced. Any questions please post back.

Something from the filter went into the dispensor valve and is holding it open. You can try to backflush it with a can of air by disconnecting the filter pushing open the valve while holding the can straw tightly while discharging it. You could also backflush it with water.
