What causes water to puddle up in dryer drum?

MIchelle it sounds like condensation from a kink blocking airflow, or possibly lint blocking ... maybe a few other things but I think those 2 are the most porminent (the following quote is from the link below) "... Dryer vent exhaust contains moisture. This added moisture, coupled with the warm air from the heating circuits will add humidity ..." (humidity, of course, is the condensation which could be the reason for the puddle of water in your dryer). I am hoping the link below will help you get rid of the problem:

Thanks for coming to Hometalk for help. Good Luck :)

How wet were the items befor going into drum? Did the washer spin at all? If the washer is working correctly there should not be water in the drum.

I found an answer to your question on Quora, written by Michael Grimshaw, Home Appliance Repair Technician, 15 years.

First I'll assume the dryer has not been recently submerged. If it had, you probably wouldn't be asking on Qoura. Next I'll assume the water is in the basket, not under the basket with the motor and other electric bits. The water in the dryer came from the dryer vent. It condensed on the walls of the basket and collected in the bottom of the basket. In every case I've witnessed, this excessively humid air came from another operating dryer through the combined vent pipe tubing. I recommend changing your vent pipe setup so each dryer has its own four-inch vent pipe all the way to the outside. Running both dryers at the same time would prevent this from happening (since if they run at the same time they are both blowing air outside.) This should be considered a temporary measure because the situation is less than ideal and wastes a lot of energy. The excess humidity will also get into the mechanical and electric bits of the dryer, causing corrosion and premature failure. I recommend correcting the situation ASAP.

sounds as though your clothes aren't wringing out properly in your washer first.

Your dryer vent piping or vent is loaded with lint. This creates a restriction for the dryer air to escape. You need to clean the piping and vent.
