Driping water Ice is collecting in the bottom of the freexer and then dripping on to floor

You have a blocked drain in the freezer.when the machine gets cold ice forms on the evap. coil that's located in the freezer and behind the inside freezer wall.when the machine goes into defrost the heater comes on and melts the ice off of the coil and it drains through the hole under the evap coil and then runs down to where the compressor is and then evaporates from the heat of the compressor and condenser coil,your drain is blocked so the water is now draining onto the floor.use a hair dryer to melt out the bottom draw if it's frozen in,remove it and look at the back wall,if you can't see the drain hole you'll have to remove the back inside wall of the freezer,to get at it,also unplug the machine or shut it down,you don't want to be blowing warm air into the machine or you'll have another problem the air ducts will freeze up.keep heating the drain hole with the hair dryer and any other ice you see,i use a steemer to clear the drain line but if you don't have a steemer you have to get something to push air through the drain like a turkey baster or similar,also 1/4 inch plastic hose like the kind you use on a fish tank works good,you can snake it through the drain line,when you think the drain is clear pour hot water into the hole if it drains through you're done if not keep hitting it with heat and use the turkey baster to try and push whatever is in there out to clear it,then pour hot water until it drains.it usually will take around 30 to 40 minutes to do this but with a steemer i get it done in around 10 to 15 minutes,good luck
