Lint bypassing lint filter and water in vent transition hose
My dryer vent goes straight up in the wall about 10 feet and in the attic it makes a 30-45 degree turn and travels another 6 feet before it exits the attic thru the roof. I have to remove the transition hose from the back of my dryer about every 2 months because it is packed with wet lint. Lately water is leaking out of this hose at the dryer fitting and leaking onto the floor. It takes close to 2 hours to dry towels. I have to pause the dryer and restart again to get it to complete the load. Lint also builds up right outside the top of the lint filter and around the door seal. I push a long vacuum hose up the vent each time I clean out the transition hose and also reverse the shop vac and blow the vent. There is no back pressure when I blow out the vent so it seems like the vent is clear. I can see up the vent to the turn at the ceiling/attic tranisition and it is clean.
Also, it gets below freezing where I live in the winter, and I wonder if the warm moist air in the vent condenses before it exits out the roof and falls back down the vent.

you need to clean out the dryer.somewhere lint is blocking the air movement.pull off the vent line,if it's long blow it out with a leaf blower,then clean out the duct that the lint filter slides into and vac out the cabinet where the motor is.if it's gas you should do this once a year electric once every two years.
before you call a repairman. check 2 things vent hose behind dyer for a kink or a restriction ( lint build up.) if your vent hose goes straight out make sure nothing is clogging the vent or the flapper outside, if vent goes up and through attic then outside vent system may need to be cleaned out. lowes sells a cleaner brush extension that you can buy and snake through your vent . this should be done yearly. we get service calls on this all the time and 9 out of 10 its not the dryer, but a ventilation problem, if the hot humid air cannot be released outside the dryer cannot dry your close. hope this helps. p.s their is proffesional companies that strickly do dryer vent cleaning if you would not rather do it your self.roughly 65-145 dollars depending were you live and who you use todo it.
Since you know for sure the dryer is heating, the problem most likely is lint in the dryer tube. You will have to remove the back panel of the dryer, and then remove the dryer tube. (Not the vent hose, although you may want to make sure that it and the dryer vent itself is not clogged). Remove the dryer filter and normally the 2 screws that hold the vent tube in. Remove the screws from the vent tube and get the lint out of the tube. There may also be lint around the fan. Get it all out. Be careful though, all the edges are sharp and will cut you if you slide your hand along it while "sweeping" out the lint.
Is the vent 4 inches all the way out? The recommended run length of 10 feet is max, however not very practical or followed. You need a vent brush to run completely through the full length and get as clean as possible. The water is from condensation caused by the long run through the attic. Any kinks in the vent will exacerbate your problem. If you do not like the dryer being 4-6 inches from the wall for the elbow, there is a kit available at most home centers, Lowes, Home Depot, that gives you the same volumn as the 4 inch round in 2 inch flat.

The vent hose/pipe should be as short as possible to vent the dryer outdoors. If it is too long, cut it to the needed length. Also check the inside of the entire pipe to make sure there is not lint piled up in it. Finally check inside the back of the dryer where the vent pipe attaches to be sure it is clear, and the vent outside the house to make sure it is clear and not blocked.
Have you checked the lint screen? pull the lint screen out and remove the lint then hold flat and pour water on it. Does the screen hold the water or does the water flow through? If it holds water, then you must actually clean the film that has coated the screening material. Use dish soap and scrub lightly then rinse clean. and check again.
It may not be your heating element. Your dryer lint vent pipe out the back of the machine or maybe out the
side may be plugged. You may not be able to see this right at the machine as the lint buildup may start further out as the air moves down the line. You have to pull the machine out and clear
that pipe or rebuild it out to a soffit vent or static vent if it is in
the attic, or out through your crawl space. This will make a huge
difference. If that hot air and moisture doesn't get out of the
machine it just goes back into your clothes.
Turn the dryer on, go out to the where the vent exits the house. Feel the air coming out, and it should blow very strong, and for the total diameter of the discharge. If it doesn't, the vent pipe is plugged, or the connection hose from wall to dryer is crimped/collapsed when pushed back to the wall.
Also make sure lint filter is clean, and the grill inside the dryer where hot air enters is clear.
you need a dryer vent brush first,bought at home depot cheap,and clean the entire vent to the house,then clean where the vent hooks up to the machine,if your filter is where your door is pull out the filter and stick the brush in there and pull out lint,also use your vacume,remember you let some lint out when you let the hose blow out but theres a lot more there to clean,and also unplug your machine as you do this,if this helps please give me a fix ya vote
