Evening, i have recently perchest a siemens IQ700 condenser dryer and i need a little help. I have started to notice creasing quite recently, my old creda reversair dryer never creassed anything. Ive tryed using the less ironing options and still things get creassed but not as mutch. I love this dryer but the creassing issues are driving me absoloutly mental.

Try shaking the laundry before putting it in the dryer and separate the stuff.

Heat pump dryers are actually closed loop dehumidifiers, so they use very low heat and no high temperature steam forms in the drum. It's the steam that "irons" the clothes. Without it, you'll have some creases.

Reconsider your washing practices

Sounds like you need to treat your washing the same way you would when line drying: the aim is to not put creases into the fabrics.


From experience, the best way to avoid creasing at the wash stage is:


- Medium loads (not stuffed to capacity)

- Lower temperatures (anything over 40*C is bad news)

- Moderate/short spinning: keep it to 800rpm or so/use the synthetics cycle or one that pulses the spin so clothes aren't stuck to the drum for the entire duration (good news for wear and tear on your washer too)


Also, remove clothes from the washer promptly when the cycle has ended then shake/smooth it out.


I'm no tumble drying expert - much prefer to line dry - but in terms of reducing creasing the only sound advice is not to dry heavy items with lightweight ones and don't overload.


On a more positive note, do you find the cooler drying temps kinder to your clothes? Is there less shrinkage of seams? Does the laundry retain its scent more and therefore emerge vaguely fresh?


Just tumbling clothes when wet even on the cold setting will help quite a lot to pull creases out of the load - I nearly always use the cool tumble in the dryer to ease out creases before hanging. At least the clothes don't look quite so much like old rags when hanging up that way! So it's not all about the heat, you know...


Good luck in the meantime. Looks like a very smart machine you've bought! Is it quiet?

A different operating concept!!! I was most disapointed with the V-Zug Heat Pump dryer when I first got it....with up to six double bedrooms to service most weekends and more bedding & towels before and after the wash-ins I relied on the Maytag or vintage dryers to "Dry Ready For Fitting" I spun everything fast 1600rpm and many blended quilt covers and bedsheets usually only took 20mins in the dryer..any creases obtained in the max extract spin where lost with the Heat / Steam from the dryer..and I benefited from fast dry times..

With the Heat Pump dryers these work by extracting the moisture left in the clothes by the Heat Pump technology which doesnt use heat, (Very Cheap)but heat does build up by the residual effect (Weird reverse action than a normal dryer that produces heat at the start and then goes cooler)

So all this bedding spun at max extract etc never dropped the creases by using the HEAT PUMP EFECT and also the drum never gets warm or heats up like a traditional dryer, the traditional dryer acts like an IRON dropping the creases out of fabrics and they drop onto the WARM/HOT drum.

You will have to reduce your spin speed for mixed fabrics, leaving more moisture in them, so less creasing and the heat pump dryer will extract the moisture - you still save on money but you dont on time...

With any new technology its a different process, in this case a very different one!!

Thanks guys!
Mike: my siemens doesnt reverse but it has a spoke in the back of the drum to stop tangling of garments.

Alex: thanks, its very silent in use but makes weird noises when it flushes the heat exchanger through and when the circulation fan is powering up. i can still smell softener on my laundry and things are soft when they come out.

I can get you all more phots if you want :)

Actually need a high heat or steam to de-crease laundry being tumble dried, the older classic dryers like the Servis MultiVents had a very high air flow and a low 1.9kw heater, the warm airflow and heated drum de-creased everything fine and dried quickly....

That was the thing I was also surprised at when I had my first zanussi condenser the door after 10mins and everything ( even delicates) was steaming away just waiting for the condenser to keep up & condense the steam to water!!!

Listen to Mike!

If you wanna get better results with the Heat Pump dryer then listen to what Mike has to say - he explained the concept to me recently & it made more sence than i'm sure most manufacturers instruction manuals do for these machines!

It did kinda make me glad to still have access to a regular condensor - i'm not especially grateful when the electric bill arrives but it is nice that it steams everything so much, it almost does the ironing for me aswell!

And I also follow the same method when I use my white knight 447wv dryer that lives in my shed, revers lasts for 10 secs which is a joke but its a good dryer but pails in comparison to my
