My upright freezer has a small amount of water inside that freezes, creating an ice slide in bottom.

The defrost element has failed, ice buildup will be noted at the inside rear of unit lower. Replace defrost element (service tech required). fixed and many years trouble free, very common.

Hello, The drain behind the back panel in the freezer is frozen or blocked up. Remove the back panel remove as much ice as possible and pour boiling water in the bottom section under the evaporator. be careful not to touch the aluminum it will cut you or break. you will see the drain hole sometimes it takes a while to thaw all the ice. Hope this helps and please rate me Thank You.

You have a defrost drain that is plugged.You need to locate it and clean it out. Hope this helps.

There is a drain the back of the freezer that is frozen. Your trickle of water comes from the ice that melts off of the refrigeration coils during the defrost cycle. You need to turn off the freezer, then remove the rear cover from the back wall to expose the coils. With a hair dryer, melt all of the ice. You will find a drain under the coils. Melts all of the ice in this drain so water can get out of the freezer. When this drain is clear, you can put everything back together, and your freezer should work normally.

Hi,
Here is a tip that will tell you where the water is coming from and how to fix it. The drain hole has froze shut and the water from the defrost will not drain out.

you could have a freon leak allowing the pipes to freeze up

You will need a professional at this point.

the draining pipe is block with something, you can melt the ice with a hear drier or hot water, then put a wire true the pipe and after that, test the pipe again.

thius suggests the defrost system not working and the defrost drain blocked. take off the back panel inside the freezer, melt off excessive ice and free the drain at the bottom with hot water and patience

I looked at the BACK at the bottom underneath of my Sears Kenmore frost free upright freezer and what was causing the ice buildup was very simple. At the factory, the assembler looped the little hose too high and when the water went into the hose it could not get out due to being too high in one spot! An ice dam will form, blocking ALL water coming through
and freezing up any more water coming down giving you a HUGE wad of ice that is scary!!! I just removed the screw holding the loop that holds the hose and put a bit of warm water down the little hole on the INSIDE (Behind the grate) to melt the remaining ice in the tube.You need to take out 4 screws and remove the grate to see this. I could not believe that this was the problem! I haven't had any ice build up since.Now don't tear your freezer apart before you try this trying to fix the compressor, thermostat etc. It may be the only thing wrong with it!
