Start by checking the manual or automatic defrost. If the freezer drains water at any other time then, there is a problem with the unit that will have to be addressed by an appliance repair professional.
Check the freezer's drip pan to make sure that it is not filled to the point of overflowing. If it is, simply remove the pan and dump the excess water.
If the drip pan is empty, make sure that the drain hose is connected to the coupler and that the hose has not become pinched or cut. If it has been cut, use a hose coupler into the hose and clamp it.
Check the hose clamp to verify that it is positioned to meet the coupler.
If these suggestions don't resolve the problem, call an appliance repair professional to further diagnose and repair the problem.
Make sure that he freezer is plugged in and the outlet is working (plug in a lamp to test).
If the outlet is not working, verify that there are now tripped or blown circuit breakers.
Inspect the freezer's electrical cord for signs of damage.
Element extension cords as a way to plug in your freezer.
If all of these suggestions check out, it is most likely the freezer wiring. Most likely a short that needs to be repaired.
Check to make sure that the door seal is not damaged. The slightest tear or hole is enough to cause ice build up.
Make sure that your freezer is not too full.
Check the thermostat to make sure it is set correctly or to see if it is defective or damaged.
Check the freezer's defrost mechanism.
One the problem is solved, remove the ice build up slowly by letting it melt on it's own, collecting the water in a pan.
