Bosch fine adjust - drying targets

replying to henene4

wow, these were all so interesting to read, i'm shocked by the amount of interesting and detailed info. thank you so much.

but i'm confused by two things. sorry for asking you a lot.

firstly, the way it washes condenser in the back is way more complex than i thought. it says it only washes it every 75 operating hours, and on standard programs. what do they mean by standard programs on that, which ones are standard? for example 90% of the time i use the program i saved on “memory 1” which is synthetics cupboard dry extra with +2 drying target and low temperature. would this be considered as a standard program? i hope it does haha. at one part it talks about how programs behave and their features, maybe they wrote about that there, i would be really happy if you can check if the program i talked about flushes both condenser and the evaporator. is there any indicators to understand while it's cleaning both condenser and evaporator? like would i hear a sound or does the selfcleaning part gets longer?

and secondly, can you please check if the “care programs” which is used to manually start the flushing programs include the both condenser and evaporator washing? there are two care programs, i wonder if they both do it.

thank you again. btw some of the pictures were so hard to read, and i didn't understand most of the temperature target things. for example is synthetics cupboard extra targeting for less heat compared to cottons and mix? are a+++ devices running less hot than a++ devices?

idk if that's possible for you, but i would love to read this whole document/pdf so much for my AutoClean model. i promise to not share it anywhere, it's just for my interest, and for since i'm too eager to learn about these all. i can give you my email if you can send it to me, i would appreciate it sooo much.

let me know about these please, thank you and have a good day

Can't share that on here anyway.

The targeted temps for fan cycling are - for those models that display them - the same, regardless of cycle with very few exceptions.
Delicate fan cycling temps are somewhat lower by a couple of degrees.

As far as I understand "standard program" means just any regular program, just not timed cycles or very short ones.

The care cycles aren't described any closer, but they mention that the message to run them is displayed either after 300h or if 10 of the condenser flushing cycles have been skipped (due to special cycles or to little water).
That indicates that they both do run condenser and evaporator flushing cycles.

Thank you henene4. Do you think this is better than LG?

Do you think this complex AutoClean system clean itselfs better than LG's Self Cleaning dryers? Do you know how those work too? Thank you.

Correct, mine is a WTWH7540/12. When idle, the temperature readout through the service menu says 23C (and also 30C, which presumably is that dummy value). It also shows Lo and 253 when consecutively pressing the four buttons above the display left to right. I'll see if that 23C value changes the next time I dry a load.

Thanks for the screenshots. Super interesting.

LG SelfClean

It's simpler in certain ways and more complicated than others.

Not better or worse per se, though their inverter heat pump is way more flexible than the BSH ones from what I experienced.

an another question to henene4

Home Professional dryers has an additional fan that's right back at the TFT screen.

I know this is probably there to the block the possible condensation reaching the screen, but is there any explanations of the fan on the service documents you posted? Why the Home Professional washing machines don't have it, but the dryers do, even though washing machines generally create more steam/condensation?

I would love to read about it, thank you so much!!

Dryers most definitely create more condensation for sure.

Let's say you have an 8kg load spun at 1400rpm.
At 50% residual moisture, that's 4kg of water.
Now run that through even an A condensing class dryer, about 10% make it out if the dryer.
That's 400g of water - that's like 2 normal size drinking glasses.

Your washer does not aim to evaporate water, your dryer does.

I think there was also a fan for the inverter board. Kenan763 has a video showing it, which I linked previously.

Been running two Extra Dry cycles this week. Initially, the timer adds 16 minutes when going from Normal to Extra. However, it actually added 22 minutes for the extra drying. On both cycles with different loads. Conclusion: set and forget and only return to the dryer once it's done. No use in making sense of the thing. Clothes come out dry, that's good enough.

So…. My sister has now taken my Bosch to use instead of using the washer dryer to dry. But the last 2 loads, it hasn’t dried properly (total mix load), thinner items coming out dry (as you’d expect) but the more cotton items still quite damp (50/50 split loads). I’d expect it to do this if only 1 or 2 items were cotton but not this amount. It’s annoying as if you seperate, it cannot sense the fleecy type fabrics at all and stops immediately, forcing you to use time dry. This is using the saved programme which I saved Mixed fabrics with cupboard dry +3. Now I’m thinking if it would be better to save cotton cupboard plus +3? Doubt there is any temp difference between cotton and mix.
