Hi Alex
Likely to be one of three things. I hate washer dryers. Mine is always breaking down.
If you are confident take the filters out and make sure they are clean and free of blockages. You might find a blockage which means the hot air cant escape from the drum hence the hot and moist clothes.
Failing this the most likely causes of dryer failure is either the dryer thermostat (on top of the dryer box a little circular disk with two pins and wires attached) or the heater eliment.
The thermostat will cost less that £10.00 if you can fit it yourself otherwise it may be the heater eliment which again should cost less than £30 if you can fit it yourself.
If in doubt take a picture first so you know how it all goes back together again.
Failing that get a pro to do it but it will cost you!
Also do a visual check of all wiring. Drums vibrate alot whilst spinning so a wire could have come off.
Hope this helps
