First of all, have you read the
review?
1). I don't know what you mean by a 115V adaptor. If you mean the 15A vs. 20A mode, that is covered in
First Impressions. In a nutshell, 15A mode prevents both heating elements from coming on at the same time. In 20A mode, the heating elements in the brew and steam boiler can run at the same time. Except for startup time, most will never notice the difference.
2). Sounds like the volumetric dosing isn't set correctly. See
Setting the Auto-Dosing for instructions.
3). Yes, condensation in the steam wand is normal. Purge it into the drip tray before steaming milk.
