Bosch Heat Pump Tumble Dryer - WTF?
Discussion
Had this thing delivered and fitted on Wednesday - heat pump tumble dryer):
Apart from having to basically re-fit it myself to correct kinked pipes, it works Ok-ish (washing always seems to be not quite dry)
I fitted an additional spur to the adjacent sink drain, so I wouldn’t have to empty the drawer every time. The drain works - I temporarily fed it into a bucket to check, but the drawer still gets a load of water in it:
I phoned Bosch twice today - first time they said the black plug (just visible in the top recess) needed to be fitted to a drain on the underside, so I did that - no difference. Read the manual again, and that says to remove it (logical); did that - no difference, still loads of water in the tray after a run, and in the bucket.
The drawer itself bears little similarity to the manual image, plus it’s got a kind of valve lever on one side which appears to do nothing in terms of draining the water. The tray appears to be some kind of labyrinth, where you have to tilt it to allow the water to drain. Trouble is there’s always a bit left, which ends up on your foot:
So now Bosch are sending someone round next week. In the meantime has anyone else got one of these apparently rather poorly documented machines? If so, any idea what’s going one with mine Thanks.

You usually have to disconnect a hose on the back bottom that feeds up into the tray. Where you disconnect the tray feed you connect your hose that runs to a drain. If this is done you shouldn't be able to get water in the tray at all.
Yeah that is done, the orginal pipe is in its stored position on the blind spigot - I checked (even though it must be right because water flows out of the drain pipe that goes to the sink drain.The only other way water can get in the tray is either through the hole in the top where the filter is, or up through the tiny drain hole.
It's a mystery.
Our beko drier does this. I connected it up as per the supplied instructions which include a tee piece, so the pumped water can go to either the tank or the drain. The connection to the drain isn't much lower than the tank so we get water going to both locations.
I've since found a different instruction from beko online which doesn't use the tee piece, so water can't go to the tank. I guess the downside of this is that if the drain gets blocked, it just leaks out somewhere rather than going to the tank and triggering the "tank full" error.
I plan to lower the drain connection one day to hopefully solve the issue.
How high is your drain connection in relation to the tank? Maybe yours has the tee connection internally.

That’s a good call. The drain is about the same height as the tray, but reading the instructions, it says to use a hose guide (the n shaped thing) between 80 and 100 mm high, and loop the drain over it, then to the sink drain. This hasn’t been done.I've since found a different instruction from beko online which doesn't use the tee piece, so water can't go to the tank.

I wonder if it forms a syphon to drain all the water, and without it, the excess goes into the tray?
^ As above, if you have the outlet hose connected and free to drain (ours goes into the same waste as the washing machine), just ignore the drawer most of the time. I periodically take the drawer out and rinse the mesh kettle-style filter.
If you keep the drawer horizontal when you do take it out, it shouldn’t drip. If you feel that you want to empty it, you can water the garden with it, but don’t drink it!

Well, I've instaled the n bend and there's a load drying at the moment, so we will see.
It doesn't say in the manual that water will collect in the tray, and Bosch service told me on the phone (in no uncertain terms) that the tray should remain completely dry when the external drain is fitted.

Ours does the same. In the manual I think it says this is deliberate as they use some of the water to clean the condenser
Mine does this, as far as I’m aware it keeps a store of water for cleaning the condenser and dumps any excess into the drain pipe. As mentioned before, you need to reconfigure the hoses on the back and the various bungs and filters in the drawer to swap it from manual emptying to drain mode.Ours is a Serie 8 - about 2 years old, and the same layout as yours, just wearing a different set of graphics.
I think that the extracted water enters the tank via the recess just behind the blue filter.
About 3-5 minutes from the end of the cycle it pumps the extracted water out of the machine.
The water container on ours looks very similar to yours - the white lever shown in your second picture is what I think empties the water out of the machine, operating the flap with the rubber gasket in the base of the “tank”.
Just looked at ours now and the black rubber bung seems to have gone walkies…

I have this model. I’m not entirely happy with it. Clothes rarely feel completely dry, as you have noticed as well.
Also the “auto clean” statement isn’t really true, you have to manually empty the filter at the bottom almost every time or it becomes less efficient. Doing so is a messy job.
Wait a few months and you will get a message “CRE” when you turn it on. This means it needs cleaning, to avoid bad smells. You have to re-fit that little black plastic bung, then fill the reservoir with warm water and run the machine (for a few hours!). Then a few months later the message will be back. So don’t lose that bung! According the the manual, we are also supposed to add a special cleaning fluid every third time we run the cleaning cycle IIRC.

I've got a Bosch Series 6 heat pump dryer. Works really well. Experiences clearly differ!
Change the cupboard dry setting if you haven't already and your clothes are damp.
If you've followed the instructions, removed the drawer, removed the black bung and put it in the 'storage' hole it should drain without problem.
The fluff filter is a 5 second job - lift out. wipe, put back.

I have to undo 4 blue plastic catches, then pull out a 45 degree filter - which is indeed 5 seconds to clean - but after that there is a plastic clamshell type tray sitting in a permanent pool of water which you can pull out, and is full of wet fluff. It gets full every 3 or 4 cycles, depending on what you dry. If I don’t clean it the machine takes noticeably longer to run.

I'm talking about the plastic cage that sits in the door opening. Open door, lift out filter. No water present, bone dry. It's a mesh that collects fluff.
I've lifted it out here. The front panel below the door I opened once after about 18 months and nothing doing there at all.
The drawer is here. It has water in it but is connected to the drain. I've also added a picture to show the bung storage spot under the blue mesh storage spot.
This is inside the bottom flap. Some dots of water but nothing in there.

I didn't even know there was a flap at the bottom of the machine
And the blue filter storage thing?? My filter is in place in the tray - why is it stored there?
The filter just inside the door collects fluff quite rapidly, but so did out old dryer. No problem to empty it, and it's always bone dry anyway.
According to the Bosch service engineer who came round on Tuesday, the tray should contain water after each run in order to keep some filter or other purged. That water gets replaced during the next cycle. So if your tray is dry with a plumbed in system, something is wrong.

The blue filter is there as that's where the instructions say to store it when it isn't used for the cleaning programme. And the blue filter storage thing?? My filter is in place in the tray - why is it stored there?

We must be talking about different machines:
1) On mine the instructions say that the blue filter must be in place during normal use. It’s self-cleaning (hence the need for water in the tray that reverse-flushes it somehow). Instructions say nothing about ever removing it even for cleaning.
2) Nowhere in the instructions does it mention water remaining in the tray (even though it should)
3) No mention of a lower hatch for anything. Appears to be permanently attached.
4) the clam-shell lint filter behind the door only needs emptying when a warning light comes on.
It’s all stupidly complex and confusing to me for something that just needs to dry a few clothes, and seems doomed to a lifetime of finnicky maintenance and minor issues. Despite the relative inefficiency, I’d have the old one back any day.
