Bosch WTW85461PL: Proper Dryer Drain Installation with 30mm Wall Outflow & 15mm Hose

Question

Hi! I would like to connect the Bosch WTW85461PL dryer to the drain so that water does not accumulate in the drawer. Together with the dryer is a set to connect this, but I have a problem. The outflow that I have prepared in the wall has a diameter of 30mm and a drainage hose from a dryer of...

Borutka · Answer

It is not the washing machine and the outflowing water has no pressure. It will not fall out alone.

I asked about something else - how to connect it? The manufacturer claims that it can be connected to a drain, which is max 100cm from the base of the dryer so somehow this water must be pressed there.

strucel · Answer

After all, in each dryer the tank in which the water collects is in the upper part so somehow this water must be pumped there - what the difference is to the tank or to a similar height located at the bottom. As the attached accessory is not suitable, you can easily get the right adapter in the stores

zhudomel · Answer

If the hose is to be connected to the tube from the second photo, it is possible to "thicken" the hose by putting a few-centimeter piece of the second hose on its end and insert the 32/25 mm reduction gasket (smaller ones I have not found) into the drain. You can also - as it is most often used - insert a 32 mm plastic sewer plug into the drain and drill a 15 mm hole in it.

The attached set fits most probably to the siphon under the sink with the appropriate entrance. It is unlikely that he will get the adapters.

maczkus · Answer

I bought such a 32/25 seal yesterday. I will try the way you write - put a piece of a thicker hose on the tip of it. I also have a sewer plug in total - thanks for the hint!

strucel · Answer

Enter in goolge 34/14 gasket - used in urinals, I suspect that this 30mm description of the author is a big mistake.

Borutka · Answer

If there is something combined with non-normative elements, then it is necessary to ensure perfect tightness of the connection, so that odors from the sewage system do not get out.

Jsk76 · Answer

Personally, I used a tee, and the reduction gasket for the dryer hose was made of a rubber stopper.

kaczakat · Answer

The subject has a bit, but if someone looks in and does a cuckoo, it will be uninteresting, so I will add something. Bosch has a condenser cleaned with this water from the drain, if you do this drain, this function will of course not work. The pump pumps water into the tray, from the tray to the exchanger and back to the pump tank. It's true that after 6 years, I still have to rip it and clean it manually (that's why I came here), but why bother you for something new ...

Hello.
I found a similar problem when installing my washer and dryer. I found a solution that can be useful to users. In Castorama, you can buy a McAlpine siphon for washing machines (price: PLN 25). Unlike other siphons of this type, this one has a blue plug from the top that can be removed and put a gray end from the hose in this place. I personally sealed it with 3/4 inch o-ring. In the middle of the siphon there is a valve that prevents "falling" of water from the washer dryer. The whole presents photos. I hope someone will find my solution useful.
Greetings.

zhudomel · Answer

No, this valve prevents smells from draining into the washing machine, which is not so necessary in the washing machine, because water is always in the drainage hose and fragrances are not likely to get through. By connecting the hose from the dryer, instead of this plug, you can pour odors from the sewage system into the dryer. Unless you're lucky, there will always be some water in this tube.

methaman · Answer

It is exactly as you wrote. The hose from the dryer is quite long and in itself acts as a siphon. Pzdr.

gozdzik77 · Answer

Are not you worried about the fact that the washing machine letting water out, pump dirty water into the dryer through this siphon?

tomruch · Answer

@kaczakat Are you sure? The dryer is adapted to external drain. The self-cleaning function should work independently, which seems to be confirmed by the instruction: Residual water in a container for condensed water, although the dryer is connected to the condensate water outlet. This is not a malfunction, and in the case of a condensed water outlet, condensed water accumulates in the condensed water container due to the self-cleaning function of the dryer.

rolandr23 · Answer

Okay, can this gray end be bought somewhere? Exactly the one from photo no. 1 because they gave my Samsung only a snake.

Some time ago I came to this topic looking for a solution to an identical problem. Today I came across the siphon visible below, so I share the find: Producer: Scanpart Product code: 1130710015

marekwroc · Answer

@arxas89
I'd like to dig up a bit of the topic because I'm facing this problem. @arxas89, this connection is available in stores, casto or lm, but the question is different - how to connect it? There is a thread and it can be connected to the sink siphon, where places for such connections are prepared, but to the sewer ⏀ 50 how?
I corrected TONI_2003

Marsal20 · Answer

@methaman By connecting the dryer and washing machine to the drain, with the modification of the siphon proposed here, will there be no problem with partial pumping of water from the washing machine drain hose to the dryer drain hose? Will the rubber ball inside the siphon, under the pressure of the water coming out of the washing machine, block the dryer outlet sufficiently that the problem should not occur?
