I have a 12 year old Pasquini Livia 90 expresso machine. I hadn't back flushed it in probably a year, and didn't have the Cafiza powder, and mistakenly bought Jura tablets and dissolved 2 in the tank as directed by a salesperson at SurLaTable and ran through the machine. Now I realize I should never have put any cleaner through the tank. The coffee tastes fine, the hot water is fine, but the steamer makes the milk taste soapy. Have I damaged the machine and am I being poisoned?
