The Latte button actually will only steam milk-the Latte Macchiato button is what we would term a traditional Latte, with espresso and with steamed/frothed milk. As for the spraying, what kind of milk are you using? Liquids like almond milk and soy milk will do that, as they do not have the same protein structures as plain old cow's milk. I would suggest running a carafe cleaning cycle with the http://www.wholelattelove.com/Urnex/urn_rinza.cfm first. Should that not clear it up, follow the instructions in your manual for disassembling and cleaning the carafe, or call our Technical Support team for further assistance. Technical Support is available Monday through Friday, 9:00 a.m. to 6:00 p.m., and Saturday, 10:00 a.m. to 3:00 p.m., EST, at 1-888-411-5282, option 3.
