I hooked up my machine to hot water as well and it saves some energy - but not as dramatic as I thought.
I think Miele dramatically changes the heating logic once it senses a warm fill - I basically get the same wash and rinse temps regardless of what Auto senses to.
I also found that the Auto cycle can get mixed up and deliver middling results.
Mine sometimes runs a prerinse with a full drain, and then runs the shortest main wash which is less than 30min which often just isn't enough.
Mine has never done a gray rinse - Auto mostly does a full drain and flush, and then the pullsed rinse before full final rinse.
Mine still has the "Normal" cycle which is basically Auto with full soil which I sometimes though rarely use if I don't trust the Auto cycle.
But QPW is pretty efficient for a fast cycle still, so using that has come in handy if I don't need a prewash.
BSHs heat exchangers of the earlier generations were significantly different to the today ones.
With todays design I have 0 hygiene concerns - the only area that can get gunked up is completely removed from any fresh water source.
Still not 100% sure if todays upper line G7000s still have Mieles version of the heat exchanger.
I think so - the manuals at least suggest it - but I really wasn't able to tell how the current design works from the parts diagrams.
The very early ones used a separate pump and so on - very Miele typical over engineering...
