The 'Sensitive' button increases the amount of water per page 16 of the instruction manual.

Thanks- I'll be asking the miele technician why I am unable to access these option (supposed to be coming Friday). The instructions in the manual you included the link to are actually omitted from the manual I received with the machine (I did none the less follow the instructions from the manual that has them included, although without success); I'm guessing an earlier version of the same model included this functionality, but not mine, which is very frustrating. Do you have this particular model of machine and are able to access these functions?

I'd go to the Miele website and download the manual for your machine (you have to enter the model and serial number if I remember correctly) and follow those instructions.

I've been researching this machine as a possibility to purchase. Your concerns with the water levels on hot cycles are something I'm worried about as well. I wash cloth diapers so definitely need some serious washing and rinsing. I came across a way to get an extra rinse independent of the sensitive button which I know doesn't work on the extra white cycle. For cycles that do allow the sensitive button to be active, this would provide an extra rinse above the sensitive button extra rinse so 2 extra rinses. You have to select a spin speed of less than 700 RPM (so 600 RPM) which forces an extra rinse. On older Miele models, if you change the spin speed to the higher RPM you desire after the machine has started on the first rinse you can still get the extra rinse and have higher spin speeds. I don't know if this would work on your machine specifically. I'd be interested to hear how it works for you if you try it! Any further thoughts on the machine a few more months in?
