#1 Does coffee stay hot indefinitely or does it shut off automatically after a period of time?
there is no machine that stays hot all the time , the health and safety rules do not allow it now so they all turn off at approx. 40 to .45 mins
#2 This seems to be making really weak coffee. How can I get it to produce more intense results?
"The advanced showerhead technology" brews steam through too fast rather than a slow drip you get from all other machines. I'm baffled by the many positive comments. I assume people are just adding more coffee than should be required. I gave my machine away.
According to the instructions, you may wash these parts in the top rack of a dishwasher. This comes under care and maintenance. I always put my previous one in and that was okay.
