Maintenance and Cleaning: If you use steamed milk, I highly suggest changing the setting to display the "Rinse Milk System" prompt to appear right after using. The default is 10 minutes, and you cannot select this rinse from the Maintenance menu. The quicker you rinse out the milk residue, the less likely you are to get clogs. The manual also suggests to use the Jura Cappuccino Cleaner daily. I tend to rinse often and do a breakdown cleaning of the milk system and frother about every other day.
3) This machine is crazy smart. It knows exactly when to clean itself, or tells you when to start the cleaning cycle. To clean it, all you do is insert a tablet in the coffee powder drawer and it does its thing. It knows when it needs water, when the filter needs to be changed, etc. In fact, since we have a water filter built into our refrigerator, we just use that filtered water in the coffee machine and therefore we don't need to use the expensive water filters. Bottom line, if you just pay attention and clean the machine on a regular basis when it tells you to, this is a no-brainer machine.
