I'll run a test to see what the max temp it can get to is. Might be delayed a few weeks due to some family stuff, but I'll get around to it. |

So just got my T1 and running the normal cycle with it set to extra dry and even having the dryness set to max in the settings when the dryer is finished and I open the door my glasses fog up and there is a slight moistness to the laundry. The laundry seems to be dry within a few minutes of coming out though. And it's definitely warmer than I was expecting. Is this how it's supposed to be?
And my new dryer made all my laundry stink like plastic mixed with machine shop. I think it was from it being new as the smell is dissipating as I use it more. So far I'm not very impressed with the dryer. |

I ran a load through my dryer last night and, yes, my glasses fog up slightly as well when I put my face right in front of the door right after opening it. Increasing the cool-down time (or cool-down target temp with Miele dryers) helps in my case. In fact, I did add an extra air dry cycle on my regular condenser dryer, too. Clothes were cooler and residual moisture removed.
The thermometer I use goes up to 158F. There have been more then one occasion where it would display "max" because the dryer got hotter than what it could measure. |

Did some testing in my Series 8 Bosch with a medium load of dark cottons. I used the Cotton cycle with the normal dryness level and two increments up. The initial time displayed was 2:52 hrs. Here's the temp each ten minutes of the cycle:
00 min. - 24C | 75F 10 min. - 30C | 86F 20 min. - 36C | 97F 30 min. - 41C | 106F 40 min. - 44C | 111F 50 min. - 50C | 122F 60 min. - 56C | 133F 70 min. - 62C | 144F 80 min. - 60C | 140F Interestingly here, the temp never got that high; I would have expected more, especially since the heat pump basically kept running until the dryer shut off. Around 30 minutes into the cycle, the display switched from just "drying" to "iron dry" and the cooling fan started cycling on and off. The first flush of the condenser also takes place here and the timer finally dropped from 2:54 hrs. to 1:01 hrs. remaining. I think only Miele had a worse timer many years ago that only lit up and counted down during the timed cool-down. Around 70 minutes into the cycle, the heat pump shut off for the second time for the final two flushes, thus the slight temperature drop. I added my usual 20 minute air-dry cycle, which brought the temp down to 43C or 110F and eliminated any lingering humidity in the drum. |

Hi everyone,
I too have ordered a temperature sensor as I'm curious how hot my T8929WP gets during drying. I looked at the type of refrigerant used in the two dryers in question. The TWF640 uses R290 gas whereas the TCR860 uses R450a. The use of different refrigerants can have an impact on drying temperatures. As mine has R134a refrigerant, I'm interested to see what temperature it will reach in a drying program. Cheers Rod |

Hi everyone,
So I did some temperature tests with my Miele heat pump with a load of towels consisting of 2 bath sheets, 2 bath towels, 4 hand towels, and a bath mat. The program was Cottons Extra Dry. Total running time 90 min. These were the temps at 10 min intervals: 00 min. - 27C 10 min. - 34C 20 min. - 39C 30 min. - 43C 40 min. - 44C 50 min. - 46C 60 min. - 46C 70 min. - 48C 80 min. - 53C 90 min. - 56C Interestingly before the towel run, I ran a 3 kg mixed load of items on the Automatic Plus Normal program and the temperature profile was very different. 0 min. - 24C 10 min. - 30C 20 min. - 40C 30 min. - 50C 40 min. - 55C 50 min. - 59C 60 min. - 64C Did I put it down the higher temperature to the smaller load? Not sure. Anyway, I will test the Automatic Plus program with towels to see if it gives the same temperature profile. |

These smaller loads leading to higher temperatures. I wonder what constitutes small too. |

My regular whites load (about 25 T-Shirts plus underwear and socks for 2 weeks) today dried in just about 80min and peaked at a whopping 49C - yet was totally dry. I purposefully overran a time cycle by a lot with a very small load and the temp leveled out at just about 65C. |
