Congratulations!
You shot one of the best modern machines there are (were) on the German market. As Louis in Groningen said: One of the last ones that were made in Nürnberg.
My best friend owns one like this, it has been going strong for the last 11 years flawlessly. Ok, the sounds got some (estimated) 20% louder ever since, but still: Once you open the room window for a small crack (hearing the street sounds), you won't here the machine, not even today. The gurgling of the water on the glass of the door is still louder than the humming of the recirculation pump itself. A regular breakfast conversation in a low voice is louder than this machine, which made it perfect to be used during the night here, when electricity is up to 40% cheaper in some towns. (Hence the 24 hrs delay button).
His machine is doing some 4-8 loads a week, some on 60°C (hot), but most of them on 40°C (warm) or 30°C (luke warm). The only thing it can't handle were dog blankets, most of the dog hair has to be taken off in the (matching) dryer, a hedge-hog type rubber dryer ball helping it along.
Me too, I have heard of some people having problems with it on some internet forums, but we have not encountered any of those ever.
Still today I love to get over to his place just in order to wash my motorbike repair rags in it (using the "stains" button and some oxygen bleach in the according dispenser) because they come out even better than boil-washed in one of my own older 1960s water hogs.
Even if its overall "feel" is somewhat more "plasticky" than that of a comparable Miele, I would always go for this last German made TOL AEG.
Good you have it, enjoy!
