At least one piece of clothing per cycle gets caught in the gap between the spinning drum and the dryer housing. It leaves a burnt looking mark on that piece where it stuck.

Something like this happens when one of the drum supports wears down leaving a gap between the drum & bulkhead. Clothes can get caught-up in this gap & this will cause the brown marks you see on your clothes. Open the dryer door & look around the front & rear perimeter of the drum, if you can see a gap I recommend replacing the drum rollers. If you aren't comfortable making the repair yourself, you can contact a local appliance repair shop or the manufacturer of your Calypso dryer.

If you take front of dryer off, there is a half moon shaped piece of felt on top of door opening that most likely has worn and leaves a gap between drum and where that felt is. Replace that for right drum fit.

you have to replace the felt piece in the back where the drum rides on,the clothes are going through the gap where the felt has worn out and could be rubbing on the rollers or whatever the clothes are touching as they spin,if there's a felt piece on the front change that out too.

Sounds to me like either the seals on the front and back of the drum are worn or the glides for the drum are worn and is causing the clothes to get caught between the drum and the usually the
front edge of the dryer. The worn glides will cause the gap that you mention.

Probably you need to replace the front drum bearing. The gap between the front lip of the drum, and the bearing, is too large, allowing the clothes to get caught in there and get dirty. Hope this helps you.

The clothes are getting pinched between the drum and the housing. Check the gasket(s) where the drum turns on the housing at the front and back. If the gasket is worn there is a small gap that clothes can get pulled into. The marks are from the worn metal. Lighter weight clothes are more likely to get caught. The gaskets can be replaced by removing the drum.

Open the dryer door. Reach in just inside and feel for the felt seal that goes all of the way around the drum. The culprit is usually the top portion of the seal which supports the end of the drum near the door is worn out. This allows the drum to tip down and leaves a gap at the bottom. Clothes get caught in this gap and get rubbed and marked or rubbed clear through. Remove the front of the dryer and replace the seal. On some models the top 1/3 is replaceable. This portion carries the weight of the drum and is what wears out.

There is a gap between the lip of the drum, and the dryer housing. Usually the gap is not large enough for clothes to get caught up..
I think the drum should be removed, and the drum bearings checked for excessive wear. This can cause it. There are like 6 rubbing blocks at the front, that the lip of the dryer runs on. This is what I mean by bearings. There will also be a single drum bearing at the back of the drum, check this also for wear or damage.
Hope this helps.

Yes, the felts are what seals the unit and allows the drum to turn without much heat loss. The felt can become damaged and the clothes will get caught between the drum and the housing leaving these marks.

Hi and thank you for your request.
Assuming the marks were not there before you put them in the dryer, then there are a couple of possibilities for the marks appearing.
Check that none of the clothes lifters or ribs as they are sometimes called in the drum are not loose, as the clothes could get caught in any gaps,make sure that there is no large gap between the drum front and the front of the dryer, as again clothes could get caught here,,check to see nothing is stuck on the drum itself that could transfer onto the clothes.
Make sure the drum is free to turn and that there is no unusual noise coming from it, if it does appear to be noisier than usual ,then it could be the drum rollers or bearings are starting to wear and this could transfer grease and the like onto your clothes.
Hope these suggestions help with your prob.
Plz feel free to leave any comments and rate my suggestions.
Thanks
