LG LMX25984ST water dispenser would not shut off

Did your fridge come with a dummy or fake filter? If so put that in and see if it will dispense. It may be that the fridge software is preventing the ice maker and water dispenser from working until the filter is replaced. Some GE fridges actively prevent bypassing the filter.

On Mine, the solenoid connection fell off that allows the ice to dispense, Thank you so much!

sounds like **** in the lines or a kink in the hose

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.

Check for a kinked water line in back.  Possibly a water line has been shut off accidentally.  If everything seems fine, you will need to call a qualified LG technician to check it out.

There is a problem with the dispenser assembly where the drawer enters.  You will have to have it checked by a qualified LG technician to see what the problem is.

You have a problem with either a sticking dispenser switch or a sticking relay problem.  You will need to have a qualified LG technician diagnose the repair the problem.
