Brand new dryer takes too long to dry clothes

vent it out at the closestoutside wall point

how long is the vent run,anything over 15 feet will slow drying process

Your problem may be attributed to a clogged exhaust system (e.g.: clogged inside the dryer's vent, flexible vent behind dryer clogged and/or clogged inside wall, etc.).

Check your venting to make sure there is no restriction. If you cannot find a restriction, unhook your venting from your dryer, pull it out two feet from the back wall, and run a normal load through the dryer. If it drys fine, you have a venting restriction, and it is not the dryer. If it still does not dry with the venting removed, you have a thermostat or thermistor problem.

If your vent hose is more than about ten feet long, your dryer may not have enough pressure to keep the air moving sufficiently to dry the clothes. Is it possible you are simply over loading your dryer?

Check your dryer venting for obstruction.  Take the vent hose off and run the machine,  If it works with the venting disconnected, It is between your wall and the outside of the house.  If it still has the same problem it is somewhere in the exhaust.  If the dryer can't circulate air, nothing will dry.

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.

If you have to run the dryer 2 to 3 times as long to dry the clothes then you just need to make sure the vent hose behind the dryer isn't kinked up and the vent is open all the way out side ,,, that will fix it for you.

check you vent hose all the way to outside. make sure not blocked or kinked.

Dishwasher: I'm assuming you are talking about when the dishwasher is not running. Correct? If the dishwasher accumulates water while sitting idle, it could be a couple of things. The water inlet valve could be leaking by, or you may have an improperly installed drain line. If you do not have a high loop in the drain line, water can back feed into the dishwasher when you drain your sink. Some dishwashers have a check valve on the drain line to prevent this.

Dryer: Dryer times will vary depending on the load size and type of clothing. Properly sort laundry to make sure lighter materials are separated from denser clothing that holds moisture. For example, if you attempt to dry jeans or towels with light cottons or linens, the moisture from the denser material will transfer to the lighter material. This can cause longer dry times. Towels and/or jeans should be dried on a hotter temperature setting - usually takes 30 to 45 minutes. Cottons and linens will take about 30 minutes on a lower heat setting. Make sure the dryer exhaust vent is not clogged. If the dryer cannot exhaust properly, the dryer heating circuits will actually overheat and eventually fail. The result is a hot dryer with clothes that will not dry. If you suspect you have a dryer vent problem, remove the vent hose from the back of the dryer and try drying a load. If your drying results improve, you probably have a clog in the dryer vent EXTERNAL to the dryer. If the results are the same, inspect the dryer INTERIOR. NOTE: Rule of Thumb - The SHORTER and STRAIGHTER the dryer vent, the better. Dryer vents that are excessively long, have many bends, or run through an attic or crawl space are the worst for accumulating lint. Also DO NOT push the dryer all the way up against the wall. This tends to crush the exhaust vent hose. Leave about a one foot space between the back of the dryer and the wall and use the semi-rigid metal type dryer vent hose. It resists crushing and rodents from chewing through it.

If you would post brand name and model numbers of your appliances in the future, it would make it much easier to diagnose a cause and be able to tell how the appliance is configured. I hope you find this information helpful.
