Drain pan underneath fridge is filling on a daily basis
The system is designed to evaporate that water using the warmth of the compressor.. is your compressor warm ? (the drip tray sits on top of it) I see that model has an Ic e maker... to check that the ice maker refill is not running on too long, switch off the ice maker, by lifting the wire arm that checks the level of the ice in the storage bucket.. leave it turned off for a day or two.. empty the drain pan, and check it again after 24 hours.. but if the ice is already full, the water problem may APPEAR to be resolved already, but will return when the level drops and the ice production begins again.
If it is just condensate, then the drain pan should be able to contain the amount it produces, but 3-days straight, would indicate to me, that is not that... if your water pressure is good, it may be that the ice tray filler solenoid is being held open a fraction too long (maybe a second or so) and as the fridge is new, it will be making lots of ice to fill the container up,... so lots of small overfills.. mounting up to a full drain pan. Under normal use,.. other than parties and festive nights, when you use a lot, the water should evaporate faster than it is produced, but it shouldn't be happening at all.. if it is that, then turn the tap at the back of the fridge to where the cold water dispenser slows down slightly.. that should be enough to prevent it continuing.. IF that's the problem.
