> We tried many things, including making a drain hole inside, but nothing helped. We "solved" it with putting 1 kg of adsorbent (silica gel) on the bottom. It lasts about two months between regenerations, so it is quite usable this way.

Now THIS is a great idea! I have the same thing (converted old freezer to chest fridge with custom IoT temperature-controlled plug switch magic; though I now replaced it with a chest freezer that was actually designed with a thermostat allowing temperatures over 0 degrees celsius) and the same exact problem with the moisture accumulating at the bottom. The device actually has a hole to let the water out, but that's not helping as there must be a huge puddle of water before it even starts reaching the drain in one of the edges of the machine.

I might try that adsorbent trick, though I would imagine that I'd have to add some kind of grating on top of the adsorbent? Because I'd rather not want to place my water bottles into the adsorbent and have it stick to the bottom of the bottles.

Place a wick in the center of the puddle and run out out the drain hole and down a couple inches lower than the lowest part of the puddle.

The wick will act like a self-priming siphon, and carry (wick) the water out the hole and drip from the lowest point of the wick.

I am totally amazed by how well this works!!!

I've had the wick routed along the outer side of the fridge for a few days now and it managed to remove every last bit of water (when I placed it there were puddles of water all around the fridge) and successfully keeps the fridge dry now. The water evaporates from a piece of cloth attached to the ends of the wick as planned, so the entire system is maintenance-free now. During the first days the cloth piece was totally soaked, but now that the initial puddles were removed it is relatively dry and I could just place it under the bottom of the machine, so it is practically invisible.

Thanks again for that awesome idea!

Nice idea, thanks! I've just ordered a few meters of wick and will try exactly this. The puddle actually isn't a puddle; it's more that the condensed water drips down the four sides of the interior walls and collects at the bottom where the walls hit the floor. I should thus be able to run the wick around the bottom of the freezer in the edge to collect most of the water.

The drain hole is in the bottom, so I can run the wick through it and out of the machine. I hope to simply be able to attach a shred of cloth or something to the end of the wick in order to evaporate the water away to the outside air. That would make a nice, maintenance-free solution.
