20 Most Recent Krups ProAroma 453-71 Coffee Maker Questions & Answers


The culprit is probably the thermal fuse. It's under the bottom cover, and you have to have Torx security bits (the ones with the holes in the middle) to remove the three screws holding it in place. Sadly, the thermal fuse is not resettable. Once it's tripped, it's dead. If you have this problem, forget about getting Krups or their lame service agent, smallappliance.com, to repair it. Both contacts I had with Krups were unsatisfactory. The factory/customer service folks say that there are no parts available and to buy a new coffee pot. Great solution. You can damn well believe it won't be a Krups. Or is it ****? An otherwise perfectly functioning unit gets sent to the landfill because the folks at Krups can't be troubled to find the part number. Idiots. For your info, there are thermal interrupters made by several manufacturers. The trip temperature on the breaker is 318 degrees, C. Something in the neighborhood of 200 degrees C would probably work, but would have to be soldered in. If you are comfortable with doing that, it's a solution.

Many times the Thermal (not Thermo) fuse is soldered in line with silver solder and unless you have the ability to cut the old one out and replace it, the cost would be greater than a replacement coffee maker.

Contact Krups, and they should be able to send you out a new one. Their phone number (according to their website, www.krupsusa.com ) is 1-800-526-5377


Good luck! :)

Thermal fuse gets stuck, gently take it apart and reverse the thermal button over, clean the rust under the button

unplug the coffee maker. Let the unit cool down for say a half hour. Try another pot of coffee and see if it comes on after plugging it back in of course

The wavy lines indicate the carafe pre-heat function. When it is ON the red light blinks for several minutes and the goes on solid. It doesn't start brewing until the light is solid red.
Mine also doesn't seem to keep hot also.

Sounds like the thermal fuse (search this database under "fuse" and you'll find a discussion of it). I have yet to find the proper TORX security wrench, so I haven't been able to get to mine in order to try the things mentioned there, but I have a similar problem and what is said there makes sense.

Just found the answer!


The type 453 coffee maker offers a carafe ‘pre-warm’ function.
This feature will heat the carafe for 5-10 minutes before the brewing process begins and is indicated by a flashing red light.
To toggle this feature, push the top-right button in the control panel until the display reads "off".

That model had a likelihood of the electrovalve growing a green crystal inside the fitting where the teflon tube comes from the boiler. The electrovalve is a solenoid operated tap on the steam wand side accessed by removing the lid and the side cover. I used to take the electrovalve off completely to do the job. To get the teflon tube out you depress the silver collar around the tube towards the fitting and pull on the tube. It won't come out unless you depress the collar. You then unscrew that same fitting and clear the green crystal out with a probe or screwdriver and rinse or blow the fitting out. The fitting was sealed from new into the electrovalve with some sort of sealant product, I used to clean out the threads and use some thread tape, I never had a leak and did heaps of them over the years.
