Never heard of Miele detergent. I've been using Persil in my Miele. I'm gonna guess and say that the Miele detergent should work just fine in any front loading washer, providing the dosage is correct.
Regarding the Ultraphase usage in non-Miele machines, even with their own auto-dosage systems - these other systems are designed for liquid detergent dispensing and fabric conditioner. There is no autodosing facility for detergent and hydrogen peroxide bleach on these other machines, as Miele does.
