Question about Krups ProAroma 453-71 Coffee Maker
When I brew coffee the water leaks out of the bottom of the machine. Help!
I just had the same failure, but fortunately, had already bought a used 10-cup unit a few months back as a spare.
The component in question is a thermal circuit breaker, of the sort which does not reset. Once activated, it is destroyed,
I have been unsuccessful locating the same component on the internet, but it seems to be a very high temperature unit, with the nomenclature "Tf 318 C" which because of the lower case "f", leads me to conclude that it's designed to trip at 318 degrees, C, or a very healthy 604 degrees, F.
Similar fuses in other appliances range around 230 degrees C (446 degrees F), which is in the ballpark.
The failure is easy to verify. If blown, there will be powdery white residue on the inside of the bottom plastic cover near the part. Also, an ohmeter will show an open circuit across the contacts. (Unplug the unit before measuring!)
Screws to remove the bottom cover are three tamper resistant torx screws.
If I am unable to find an exact replacement, I will use a thermal fuse in the same power and temperature range (10 Amps, 300 degrees C trip).
Because my unit unequivocably did not experience over temperature conditions, I suspect this is a component aging issue and that there is no other problem with the coffee maker.
Supporting this is the fact that the unit works fine after I moved the good part from my spare coffeemaker to the dead one.

had the same type of problem with a hair dryer once. A thermal interrupter- I called it a planned obsolescence gizmo- died. I bypassed it with a silver wire soldered in and the hair dryer ran well until another part died years later!! Sailorb

Replacement time. a certain percentage of thse have this problem. There is a small, non-replaceable tube in the inside toward the bottom that has become melted/damaged.

The black tube that is protruding from the coffee machine is broken or leaking.If you pull out the brewunit,, you may find the broken piece stuck inside of brewunit.
