Miele TKR850 WP Dryer: Express Cycle
HTML-код
- Опубликовано: 29 сен 2024
- Thought I'd do a video of my Miele TKR850 WP Dryer doing an "Express" cycle. This is for small loads up to 4kg, though I did adjust the drying level to "Normal Plus" to ensure that thick cotton waistbands were dried sufficiently.
If you've ever owner a dehumidifier then you'll recognise the sound the dryer makes after it has been running a while - this is the heat pump working... A glorified refrigeration unit. This is used in the condensor to quickly cool hot air and extract the moisture from it, before heating and drying it up again before re-entering the drum. Clever stuff, and highly energy saving.
Does your machine completely dry the clothes? I hear heat pump doesn’t get hot, runs for hours and the clothes are still wet. I have an aging Miele condenser that drys well but it doesn’t shut off when the load is dry so I’m looking to upgrade.
This is definitely different to just condensing type dryers, but you'll get used to it. This does get very hot and dry clothes, but it has taken some adjustment within the settings to get this function like the dryer it replaced. You can adjust the drying levels in settings and also I've extended the cooling down period. For things like towels I just let these air before putting in the cupboard. Sometimes I dry things on a timed programme after but this is rare. I'll try and do a video for you!
I replaced mine for exactly the same reason. I was really pleased with mine at first, a T1 eco - not the model above, but now I don't think I'd buy it again. The intelligent reverse cycle doesn't appear very intelligent. My sheets end up in a big knot and still wet in the middle. I also feel I have to put it in for another 20 mins or so at the end - I've come on here to see if I can glean anything to get past this thing with the sheets in case it is user error. Drives me nuts! :)
@@sabistar44 heat pump dryers uses a much lower temperature to dry the clothes it is not getting HOT but warm, HOT is a big word for a heat pump dryer, HOT is above 55 degrees and Heat pump dryers uses max 45 degrees to dry the clothes and the old condensing models dry at 95 degrees. So there is no chance of clothes shrinkage in a heat pump tumble dryer.
I just recently bought this machine. I’ve noticed on the reverse tumble a dull click can be heard on every complete rotation of the drum. Noticed yours does it too... Guessing that’s normal? Did you notice?
Hello! Mine does this and I hate to tell you it will only get more noticeable with time. This is the moisture sensing components of the dryer. I think (from when the engineer showed me) two bands of metal actually run around the drum and make contact with component at the top of the dryer. This has carbon on the underside and makes contact with these bands around the drum the whole time - a small electrical charge is sent through the clothes to measure how dry they are. This is apparently a peculiarity of all Miele dryers - but if you've only recently got it I would get it checked just to be safe. I'll do another vid soon so you can hear the 'normal' noise mine makes. Hope this helps.
Hey thanks for the in depth reply! I believe you are right about the carbon brush contacts. I've been researching it. And I knew this is how Miele sense their dry levels. What I don't understand is why the sound can only been heard in the anti-clockwise rotation - quiet on the clockwise rotation. On this particular video though it seems to do it on both. If it's normal then I'm not overly bothered. Did you have to have an engineer out to look at this machine?
Glad I could help. To be honest I've got so used to it I can't recall - I think it used to be more noticable when the drum reversed, now it is there irrespective of the rotation direction. I did call an engineer out as, like you, I was not aware of this Miele system and thought it was a fault. Further advice - I've had several fragrance 'flacons' leak and pool oil at the base of the door in between uses. So just keep eye on these - I believe they fill with fluff. Still, it dries so much better than my previous dryer and I'm hoping to to move it under a counter one day, where the noise will hopefully be dampened!
sabistar44 Ahh ok so when the engineer came out he told you it was normal and not a fault. I’ve looked at a couple of other videos on Miele tumble dryers running while open. You can see that at least one of the two contact bands that run around the outside of the drum have a join. It’s a very tiny step which depending which way makes a louder noise. I may open m machine up and have a look sometime! I tend to close up the flacon when I’m not using the machine. Not noticed any leaks so far. Have you tried anything other than the aqua? I want to buy the matching washer to this sometime this year too.
Miele has used carbon brushes to contact the drum for over two decades (maybe longer). There is a rivit on the underside of the plastic arm that the brushes are attached to. Depending on which way the drum is rotating the little rivit makes contact with a join or weld in the drum.
Usually this doesn’t happen until the brushes has worn down from many thousands of hours of use. Eventually the brushes get very short and the sound will get pretty loud. We had a dryer where the sensor dry stopped working due the bushes being so short they wouldn’t maintain constant contact with the drum.
The upside is that the brushes cost about $20 or the whole arm assembly is about $35. It’s pretty easy to replace. Ours wore out around the 7000-8000 hour mark. We heard the knock, knock for years before the brushes got too short.
