LG LSC27931S Side by Side Refrigerator? water dispenser keeps on dripping after water has been dispensed?

Probably replace the water inlet valve on the back where the water supply comes in. Disconnect the water line to the dispenser there and see if it keeps dripping when you try the dispenser.

Not that this is much help, but I have the same problem with the same model.

If its should solved with an original spare part again then there could there be a marketing technical patent on some materials.

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.

Hello, Check the water fill tube to see if it may be frozen. It's a tube about 3/8" wide that hangs over the tray. Squeeze the tube and if it is hard, it"s frozen, if it is soft, you have another problem. If it's hard, take a hair dryer and thaw out the tube and you ice maker should be fixed.
I hope this helps.

IF THE WATER IS DRIPPING OUT OF THE DISPENSER NOZZLE THEN YOU NEED TO REPLACE THE SOILINOID BECAUSE IT IT LEAKING THROUGHT THE VALVE..

You may have something in the solenoid valve seat that is keeping it from closing fully - could have happened at the filter change.

If the water is dripping from the dispenser tube, you need a water valve. The valve is not shutting off completely. Check to make sure water is not dripping from ice chute. If the chute door doesn't seal off you will get moisture there and it will also frost up the ice chute.
