Tumble dryer not working

At the end of a drying cycle, the clothes still remain wet. The dryer appears to work (correct led display and length of cycle etc) but the clothes aren't dried at all. The appliance is 4 years old. An Engineer was called a fortnight ago to replace the pump as it wasn't washing but there is no error alert at all this time.  The tumble drier appears to work but quite clearly doesn't when the cycle has ended and I check the clothes. Thank you.

    I have the same problem.I changed the thermostate and it worked but after that time it turned to not working again.I don´t Know where is the air filter for the drier mechanism.I believe that is the problem, because it´s dirty.

    Yes I have the same problem as well. The cycle runs fine - no warning lights - nothing to indicate there's a problem. But when I open the door after end of the cycle the clothes are cold and as wet as they were to start with. Have checked through the manual but nothing in the troubleshooting section. Anyone got any suggestions?

I managed to solve the problem the following way: I noticed that if you unplug the Sensor-NTC(part nimber 154431 https://www.bosch-eshop.com/eshop(bD1lbiZjPTAwOQ==)/bosch/gb/prodp.htm?prod=WET2820GB%2f13 ) that controls temperature of air in the air channel, the drying cycle runs as you describe above. So this circute was checked up to the power module. Contacts of the Sensors plug were tightened; I think this solved the problem; resistance of the sensor checked. It must be 4.8K at 25 degree C. and decrease when temperature increases. I dipped the sensor in a glass with hot water.

Dryer Dry Time Appears to Jump or Stall During Auto Dry Cycles


The operation of dryers during the Auto Dry Cycles is based on the moisture content of the clothes as they cycle over the moisture sensor. At the start of the cycle, the default estimated time is displayed depending on the cycle selected. The moisture sensor feeds information to the control based on the "wetness' of the clothes during the first 5 minutes of the cycle. The control then calculates and display a new estimated time making the time appear to "jump".

Recalculation happens again based on the reduction in the "wetness" of the clothes when the Estimated Time Remaining is between 15 to 5 minutes. The control will extend the cycle and display the Estimated Time Remaining unchanged if it "sees" no significant reduction in the wetness level of the clothes. The dryer will run longer than initially projected and give the appearance that the displayed time has "stalled".

Clean the sensor bars for any films or dirt build up to make sure it sends accurate information to the control. Level the dryer front to back and side to side to ensure the clothing will tumble properly and making good and proper contact with the moisture sensor bars. Check the dryer vent duct for any restriction to ensure a good air flow as the operation of the Auto Dry Cycles is based primarily on the air flow condition.

It is highly recommended to clean the lint filter before every load and make sure the dryer is grounded at the wall plug.

Not heating


If you can hear the dryer start and operate but at end of cycle your clothes are wet then it is likely (assuming the heater is turning on) that the fluff collection on the condensor unit is blocking its operation.
Refer manual at this site and follow instructions on page 20.

E15 error code on hoover tumble dryer


Controls
  • The control unit on the tumble dryer will vary among different makes and models. The main purpose of the controls is to allow the user to select the drying cycle. You can choose the time and temperature setting on most units, while others allow custom settings such as moisture sensors and end-of-cycle alert signals. The controls may include a dial or a touch panel and LED screen display. Some tumble dryers allow you to independently select the appropriate time for the load you are drying and separate programs for temperature.
Motor
  • The motor inside the tumble dryer spins the basket to allow the clothes to tumble while being dried. The tumbling action allows the air to pass through the clothing to dry them faster. Heating laundry that is stagnant will likely dry the clothing on the outside while leaving damp clothing inside the pile. The constant motion, along with the heat and steam created by heating the clothing, reduces wrinkles. The motor also powers the fan that delivers the heated air to the basket of laundry. The heater can be an electrical element or gas powered.

My clothes come out wet after running for a length of time but they are hot


You have an vent issue..If the clothes are hot but not drying your not getting proper air circulation, you need airflow thru the unit to help remove the moisture from the clothing other wise you end up with warm moist clothing... Start unit and go outside to where the dryer vent comes thru the wall and check the airflow with your hand ,you should feel a good flow of warm air. If not some where between the unit and the vent their is a restriction either in the flex duct or the duct work in the wall which will need cleaned out before the clothes will dry in a normal time frame..Plus it cost a lot to run the dryer 2 or 3 cycles to dry clothes Hope this helps Good Luck

Not enough heat


You may need to adjust the air flow on your dryer vent.
When an LG dryer is functioning normally---the time required to dry laundry is determined by the *Sensor* located on the drum side of the lint filter housing and by the main control board.
When laundry is near dry--any Time Remaining on the control panel that is *not* needed will be eliminated---except for the last 6 minutes.
The final 6 minutes of any LG automatic cycle is for cooling down the laundry before the dryer ends the cycle.
If a dryer *counts down* to the last 6 minutes but the laundry is still not dry--the computer will allow the dryer to run until the laundry has dried or defaults (not drying within the additional time allowed).
Dryer vents that are longer than 8 feet with more than (2) 90 degree turns--can affect drying performance.
Setting the DRY LEVEL selector to *Very Dry* will solve most dryability issues. In homes with abnormally long vents--even the longer run time in the *Very Dry* setting is usually not sufficient to dry laundry loads.
Reducing the length of the vent or starting a second cycle becomes necessary to fully dry the clothing.
If a second cycle was started---only the amount of time that is needed to dry laundry will be used before dropping to 6 minutes and then the cycle will end with dry laundry.
*****************************************

LG gas dryers are more sensitive to venting length and air flow resistance. The gas burner can cause a rapid increase in temperature compared to an electric burner.
Rapid temperature rise in a gas dryer leads to premature burner shutdown (longer time required to dry laundry).
The gradual temperature increase of an electric element is more "forgiving" in homes where the dryer venting is less than ideal.
*******************************************

Problem:
The dryer has an auto dry feature which never fully dries the clothes so we wind up manually setting the dry time to an hour
Solution:
LG gas dryers are VERY temperamental in long vent set-ups. If fabric softener sheets are used in the dryer--clean the two stainless steel strips of metal on the lint filter housing with a SCOTCHBRITE PAD--scrub back & forth several times to remove the waxy residue from the fabric softener sheets. Most,if not all manufacturers do *not* recommend using sheets in dryers that have a moisture sensor (electrodes).
However--using a SCOTCHBRITE pad keeps the wax off those sensors which can be seen if looking *into* the dryer drum and at the lint filter housing.
If only *liquid* fabric softener is used in the washer--clean the dryer sensors once a month. Liquid softener also contains wax which can slowly accumulate on the dryer sensors from the laundry washed in the washer.

I have a Whirlpool Gas Dryer LGR6646BI-12 the clothes feel warm but not hot and they are still damp


The Dryness Level allows adjustment of how damp or dry the clothes are at the end of the cycle.
  1. Make sure the correct Cycle has been selected for the type of fabric being dried.
  2. If the correct cycle is selected and the clothes are still coming out too damp, use the Auto Dry Level button (Kenmore) or Dryness Level button to increase the Dryness level.

  1. If the highest Dryness Level setting was selected and the clothes are still damp, the Customer Focused Drying Mode settings that are built into the machine can be adjusted.
Dryers come from the factory set to Drying Mode 1 (default). Drying Modes 2 and 3, include additional drying time.
Note: This change will affect ALL Auto Dry cycles.
  1. Machine MUST be in Standby mode before beginning. (Standby mode = Plugged in, Power off)

  1. To select drying modes, momentarily press the Auto Dry Level button (Kenmore) or Dryness Level button (Whirlpool) again. The dryer will beep, and the display will flash and show the next drying mode number.
  1. With the door open and the display flashing the desired drying mode number, press the Start button to save the drying mode and exit diagnostics.
  1. Press the Pause/Cancel key at any time to cancel changes and exit from this mode.
Hope this works............

Dryer turns on and rotates. However, does not dry clothes completely. Cycle signals wet,then damp,cool down and finally dry,but clothes are still wet. Sometimes the dryer works fine and completely dries...


This problem may be the result of a dirty lent filter which if clogged will short cycle the dryer and the clothes will still be damp when done. Also a dirty exhaust pipe (usally 4") will prevent the clothes from drying correctly. Make sure that the air is leaving the machine. To do this you have to go outside when the machine is running.
