So, the service tech ordered some parts for my grandmas machine.
Meanwhile I was looking around and due to some luck in pricing, if the repair fails, I put in a reservation for a 1600rpm Series 8 Bosch at work.
So checking some specs, I realized something strange.
Any BSH machine - at least in the Series 8 level - uses a heck of a lot of energy.
For a 9kg load, they use 2.12kWh of energy.
Sure they reach north of 60C, but still.
AEG uses only 1.55kWh, Miele only 1.45kWh for the same load size.
And the Miele even is an entire hour quicker.
Especially the Miele seems odd.
Given it has an all metal construction, it should need more energy than the others.
Knowing Mieles water levels though, I can see that happening.
AEG and Miele only reach 55C.
But even adjusting for that, they still are a good 20% more efficient.
How can that be?
Do they use THAT much more water during the main wash?
Or why do they maintain temps that long?
Out of all these machines, that is the one still offering an option to extend the wash time.
And the one with the largest drum volume of them all.
I attached the corresponding screenshots from the manuals.
