Warning - do not buy equipment - Fehlkonstruktion condensation tank

We had for the first time 20 months after purchase, ie within the guarantee, the problem is that the IQ700 simply ran out.
It was the mistake of the other "commentators" 1 Star rating have already described.
The principle of "Self Cleaning Condenser" does not work with the device. Despite regular and careful cleaning of the lint filter, collect in the lower externally accessible receptacle not fluff. The pump clogged and the unit stops.
The state will be accompanied among others by the reports that the upper receptacle would be full, although the contrary is the case.
Because the error for the first time in the guarantee occurred, we have come a technician from Siemens. The dryer was cleaned on site. The statement of the technician was frustrating us that you can not do anything about. It would design reasons for the accumulation of lint on the site.
From "Self Cleaning" So we can not speak.
Barely half a year later (after 27 months) and out of warranty, the error occurred again.
That does not surprise because the technician could not completely clean the receptacle due to the inaccessibility or cleansed.
There is a video on Youtube that shows how to clean the pump and the tank itself to some extent.

I have therefore taken the dryer running again. Because the whole structure is so inaccessible, it is an evil drudgery. As in the video, in our control has a telescopic rod also shown that one gets the area not really clean.
(If the unit would be at least as accessible as it is the case in the video on this Siemens model, would be much helped:
[...])

After the warranty probably has the support is due to the billable power most pleasure from it.

PS: In the first few months after purchase, the dryer of us could get of course also 5 star. So it does not surprise me that there are so many good reviews, including by Stiftung Warentest, there.
It would be interesting, as after 3-4 years and often use the vote fails.
