Krups xp4050 won't brew

Hi all,

I have a Krups xp4050 that was working beautifully for 2 years and a bit ... until this week. Lately it won't brew or produce hot water. The steam function however still works fine. I thought it was a cleaning / descaling problem, so I used a sta***cks product to clean it and it worked the whole time I was cleaning it, but stopped on my second run through of clean water. I've tried cleaning it twice now. Here's what is happening when it doesn't work:

Press a button (one shot, two shots, or hot water), the machine starts normally, sounds like it will perform fine, runs for 2-5 seconds, then stops and beeps and all of the lights blink.

Any help is appreciated as I am getting quite fed up with this problem.

Thanks :)

    I have the same problem. I punch all the correct buttons, it sounds like it's going to brew, then a beep sounds and nothing happens. After several attempts I unplugged it, and that solved the problem. Once. Now that doesn't even work.

    I also have the same problem with it only running 2-4 seconds. Is there a reset or a way to return to "factory settings"? I called customer service and they said it was the pump. Any ideas????

    Could it be simply that the coffee is grinded too fine ?
    When I use it with "normal" coffee everything is ok, when I use a certain brand of Italian puds, it beeps, but not with another brand.

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

SOURCE: espresso function problem Krups XP2070

Most likely it starts the espresso but stops after a few second because the unit is not getting the water flow information or the unit is blocked. You will know that you have a blockage because not water will come out of the espresso filter but most likely you get some liquid during the 4-10 seconds it operates. My unit has the same problem and I fixed by getting a new flow meter. This unit is installed after the water tank and has wires (3) going to the the power module.

SOURCE: Descaling

No, it does not quite clean both boilers, even though they are connected, you will have to use the preground chute if your machine has one, if not then grind and brew method will work. The reason, you want to get some of the cleaner through the white plastic valve behind the brewunit and the fitting that connects it to the boiler.

No espresso coming out.

The problem with the XP4050 is the two safety valves that the water goes trough on its way to the coffee head. They are plastic and some of the parts will just become brittle because of the hot water and the contamination they gather. With my XP4050 they just broke and parts of it were in the rubber tubes that go to the waste tank.They are also very cheaply constructed compared to the more robust parts of this machine. The water to the hot water/steam head does not have these valves and has a completely different routing. I am currently trying to fix the machine with just one valve and parts of the two valves that are still good. Fingers crossed....

Water goes directly to drip tray instead of to the brewing head.

Have the same issue with mine. Descaled it all and wouldn't even brew with no coffee OR filter in the housing, so I took it in to get it checked out. Turns out it's the solenoid valve that needs replacing. ~$60 part plus $90 labor, so I've decided to try and find that part and DIY, if I can. I'll let you know how that turns out!

Flashing red light

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".

My Krups won't brew

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,, 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.
