With my previous Siemens condenser dryer, it would just add time to the cycle. Once the LCD icon switched to the target drying level, the dryer would run for 5, 10 or 15 minutes before entering cool down.
I haven't found out how BSH do it now. As you've said, adding two increments to the Cupboard Dry drying level, will give you a longer (estimated) cycle than selecting Extra Dry in the first place. My Serie 8 will add 12 minutes when selecting Cupboard Dry +1. However, once the Cupboard Dry icon lights up, the dryer will jump from eleven to three minutes remaining. Huh? I am confusion! I feel like the, say, Cupboard Dry light won't come on, unless the added time has elapsed as well. And don't even get me started on that wonky timer. The time will fluctuate down and up again by five minutes for like an hour, only to then drop to 30-something minutes once clothes are iron dry. Henrik, where you at? Oh, and kindly also explain to use what Gentle Dry does (besides adding time). It surely doesn't decrease the temp on my dryer. | ||

Depending on cycle, there are 3 fan behaviours. Either temperature dependent, on continuously or timed. Delicate lowers the temperature the fan comes on at. The documentation however AFAIK does not state which cycle does what. I'll check when I'm back at work, but I'm on holiday for this week and next week so we'll see. | ||

Henrik
I dried a roughly 4kg load of clothes today using the Low Temp option. The fan didn't come on until the time dropped and the clothes were about to be iron dry - which is normal. It cycled on for 15 seconds and remained off for 20 - again, this seemed normal. At that point the air temp was 42C. The duty cycle remained unchanged through the cycle and even into the anti-crease phase. At the end of the cycle (Cupboard Dry with one +) the temp was 62C. Don't know if that is supposed to be low or...?

62C is - by laundry care standards definition - low temp. 65C was as far as I am aware the reference temp for low temp drying. | ||

Well, today's victim was a large pillow. Had it on Timed Dry for an hour with low temperature. Towards the end of the cycle, the temp had reached 68C in the lint filter. I stopped the cycle, as 68C is clearly above 65C and the fan never came on, ever. Started another Cotton cycle with low temp and the temp rose to 68C again, at which point the timer jumped to 1 minute and the cycle ended. Tried again on Delicate with low temp: exact same result.
What I did find interesting (not that a 70C Delicate cycle isn't interesting) is how quickly the temp in the filter drops. After three minutes of tumbling without the compressor on, the air temperature had dropped by almost 10C - although the temp did eventually stop rapidly falling at around 50C. | ||

Here’s just 2 examples of mine. A regular cycle and then a timed 20 cycle which didn’t use the fan at all after delicates finished at 52c | ||

I found an old German service manual for the Siwatherm dryers - those with the rectangular door. It references the high temperature as 75C, the low temperature as 65C and extra low as 55C. Each of the fine-adjustments would add .5% to the selected dryness level.
I remember when we had these Panasonic dryers...

It’s a A++ model rated 800w, but has an A condensation rating. | ||

Yes, my WTWH7540 made in December of 2019 will leak moisture around the control panel in the Quick|Mix cycle that does not use the fan. The fan, by the way, expels air through the front of the dryer.
Not sure where the NTC is in my dryer. It's there, according to the parts list (0527), but it's not anywhere where I could see it (i.e. the filter area).

Some corrections So actually, yes, the main pump is used for flushing. The diverter I had in mind is situated in the drain pump, makeing a total of 2 thermal actuators down there max. The SC2 system has automatic filter flushing but NOT condenser flushing, so I switched that up. | ||

Unfortunately, both your dryers have revised cycle charts that do not list target temps. The 2 examples are both A+++ dryers, one with Inverter one without. The compression on here isn't doing it any favours, but should be doable if you zoom in enough. | ||

Actually, Logixx, going to through stuff, you dryer has actually an old cycle chart available and lists 65C NTC temp as limit. You dryer should be KI-index 12, so WTWH7540/12. On all other dryers, there's a testing document for end-of-line and service testing that shows power consumption depending on temperature. | ||

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. | ||

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. | ||
