Bosch Condenser Tumble Dryer: Comparing WTW85460PL Heat Pump Model and Conventional Options

In #1123 I uploaded two photos. The lint drawer (or sediment trap or second filter) is a lockable container lying in the water under the exchanger. The bottom is at a slant, also the deeper it is the more water stands. The pump's nipple enters from the top just behind the lint drawer and this is more or less in the middle of this whole space. The pump looks like it connects with a hose directly to the teat. Access to the pump is from the rear under the inspection flap, also any cleaning or replacement is 2 snaps and 2 screws. But this is probably a common solution.

Compared to the infamous 6-series self cleaner variant....

Attached is one of the exchanger flushing cycles. In my opinion it works effectively

It is a pity that Bosch has withdrawn these dryers with AutoClean and no other manufacturer has come up with something similar, as it seems a sensible solution to the ills of SelfClean type systems.

Presumably the new models (8 series) work similarly, as can be seen by the use of a filter in the condensate tank. The care programme in principle also works in the same way. However, it appears that for the user to clean there is only a small classic filter under the door, which basically forces emptying after each drying. For more access is not visible, unless access is from the back.
In my opinion, the biggest advantage of this type of system is that the circulation of lint is through a layer of water and generally there is no contact between the dry lint and the exchanger so no cobweb forms. Also, in the new models I don't expect any regression.

I still have such a vintage

How do you figure it

No imagination needed. Lint enters the filter through a section submerged in water. I have described above.

Here is an example of the effectiveness of the exchanger flush. one of the many dryers with auto cloas or self clean systems after a certain period of operation.

One of many... let's not do beauty contests. I presented a specific solution which I happen to have and which I think works, and which a colleague obviously does not have to like.

@mrice I cleaned a colleague's once by taking it apart like this, the second time went with a pressure washer and it was done

What you are showing is not AutoClean.

This is not the way to go, once with a pressure washer you will not clean the other part of the exchanger or the drain channel properly.
This technique is, unfortunately, patting the syph with powder.

It's not about competitions, it's about facts, how dryers with exchanger flush systems look like.
I will not convince a colleague by force if he does not believe the photos.

So outline the differences in construction and principle of self and auto.

I was referring to a system where there was no filter under the door, but it was in front of the exchanger. It was flushed with water and the lint went into a drawer under the exchanger. For some reason, this system was abandoned and we returned to the infamous previous solution, where the exchanger is flushed and not the filter in front of it. There is also a filter under the door.

Listen, what dryer would you recommend today where the exchanger doesn't rust and doesn't get clogged with dust? I've seen videos on YouTube where dryers have been taken apart for cleaning and in the Samsung for example, the exchanger was rusty after a few years. I have a LG slim washer dryer for 6 years and it's lame because the heater system is useless. It shrinks and destroys clothes. LG dryers, on the other hand, are one of the more expensive ones as far as I can see and there is no access to the exchanger at all, not even through the flap. The whole front is built in, no door. There is only a self-cleaning system, questionable as in all such systems anyway.

You have shown a dryer with SelfClean, this is an older system, in fact Bosch still uses it.

I think the AutoClean system was in one generation, which they quickly phased out. Supposedly due to a change in EU requirements for energy labels (although I don't know what the fart has to do with the windmill). Below is a photo.

They withdrew because it worked and probably reduced sales of dryers

is this dryer https://www.mediaexpert.pl/agd/agd-przemyslow...mp;clickid=Xi095YJsYthnxfE2vQ8Q-1774709841154 is it exhaust or condensing? https://www.mediaexpert.pl/agd/agd-przemyslow...arki-przemyslowe/suszarka-asko-tdc1772c-t-7kg

From the instruction manual for the one in the first link , quotes "Connecting the hose that discharges air from the dryer
The dryer allows three ways of draining the air: from the back, from the right and from the left. At the time of
delivery, the opening at the rear is open and the connection fitting (1) is mounted on it.
The side openings are covered with two
plugs. The machine is supplied
with air exhaust hose
(3) and two clamps (2)

The EU has probably only allowed this to be marketed by 'Professional', after all the pump lobby wouldn't allow it.

The former is an extractor, the latter a condenser.
I would no less dismiss ASKO. One, most service technicians when they hear the name will not even want to talk about coming here, two, today it is basically the same as HiSense, only many times more expensive.
