"Prewarm carafe with hot water to help keep the coffee hotter".

I tried that with normal hot water from the sink and then placed "filtered
cold water in the coffee
pot. The coffe came out cold. So I know, I need to place hot water inside
the coffe maker.

No, usually makes things worse. Hot water will not set off the sensors in
some units.


How cold is the cold coffee? If it is not heating properly, it may be a
defective unit. Take a temperature reading to see what you really have.
Most coffee brewers say something in the 180 range is the "best"
temperature, but it will drop more in the carafe. If you fall far below,
take it back. If it is still not as hot as you like, perhaps no drip brewer
will do the job for your preferences.
