freezers need good door seals to work. The fact that the freezer is keeping things cool indicate that it is working but the cold air is getting out ,probably at the bottom of the door
one method of checking door seals is to inspect for cracks,hardness
use a piece of tissue paper and place under seal at door opening and try to pull the paper out. if it comes easily then the seal needs replacing

This is just a general answer but it may mean that the door seal is leaking. Try running a dollar bill under the seal to see if that area is looser than the rest of the door seal.
Look inside the freezer for model number.

they are all like that :)

A good parts store will carry ready made gaskets, just bring a sample to match.

possibly need to clean out vents/drains.make sure door seals all round.no air gaps. blocked vents/air leaks will cause fridges/freezers to work overtime..

Hi the problem is with a clogged drain hose that's why all the water. to unclog turn off fridge. pull away from the wall . remove back panel. clean all vents . locate drain tube, by the drain tray. clean out the drain . thanks the appliance doc
