Question: why does my machine explode coffee grounds into my cup?
Document: (If you want to froth some milk, flip the second switch in the opposite direction.) Come back in a few minutes and the machine will signal that everything is at the right temperature and ready to go. You fill either a one or two cup filter with coffee grounds (or use an expensive Krups one-use pack if you are a sissy) , attach it to the machine, and you are good to go.
You turn a switch (after the wait light goes out) and espresso drips into your cup. You turn the switch off when the right amount has been dispensed, wait a few seconds while the machine, forces the last of the steam out, then turn off the power switch. At this point you can remove the filter full of used grounds and put it in the sink. I then take a moist paper and wipe the grounds that remain in the machine.
That is, unless you like cleaning up coffee grounds from corners of your kitchen that you never knew could accumulate them.5: Turn off the machine, wipe down the grouphead, rinse out the portafilter and basket, and enjoy your creationIt took me a few tries to get things right, but after finding thecoffeewe both liked the most, I was pulling perfect 1 oz ristretto double shots within a week.
I have had this machine for 4 months. For a relatively inexpensive machine, the coffee is good. That stated, for my needs, this machine does too much "thinking". You must wait for the water to heat up before the pump will work. If you want to bleed the water or pre wet the grounds, you cannot. On the steam setting, same thing, cannot bleed or blow through the nozzle until the machine senses the correct temp. Pump is noisy.
Plus they are more expensive. Eventually, I began tearing open the pods and hand tamping the loose grounds, assuming there had to be some fine science behind the weight/volume of coffee that was beyond my abilities to muster. But the included scoop is the perfect size. Depending on the grind (especially if you are grinding your own beans), you might get a taller or shorter shot, but these instructions should give you a good starting point:1: Turn on the machine.
This is  my first Espresso machine. It arrived packaged well, and was easy to get out of the box and pull the tape off holding the parts together. Compared to my Kuerig, this machine is extremely light. I like it's design better too, it's also not as tall. It comes with a Scoop/press, one and two cup filters, and the piece to put the coffee in. Directions were brief, I had to read it a few times to figure out where all the pieces went.
We're a 2-3 cup a day coffee household. This doesn't include all of the weekly trips to the coffee shop while at work for more specialized drinks. Prior to getting this espresso maker we simply brewed flavored coffee at home with cheap and disposable coffee makers. We were of course overjoyed to welcome the KRUPS XP601050 Manual Pump Espresso Machine with Thermoblock system, Stainless Steam and Die Cast into our kitchen.
I like this machine I was amazed at how much steam it would put out. Makes a very nice cup of espresso. We use it every day and have had it for over 6 months. But  a couple a months ago I noticed it was taking longer to pull a shot of espresso out of it, and then eventually it just quit! It would make the noise but no coffee would come out. I live in Alaska, so it would cost a ton to ship it back.
It requires you to turn over the arm and tamp it several times to try to remove the coffee grounds. It does not eject cleanly and I always end up with a mess on my countertop. Plus, banging that coffee arm in the morning is LOUD!3.
I typically run 1/2 cup of hot water through the machine without coffee into an empty cup to warm the cup and the head. I then fill the device's coffee basket, dump the hot water from the cup and immediately brew espresso. When the cup and the head are warm to start, the espresso is hot. The device has an automatic shutoff and cleanup is very quick. The appearance is elegant with clean, simple lines and a bit of an art deco feel to the design.
Answer: make sure the cup that holds the coffee is in place.I threw mine out the first time I used it by mistake and had the same problem.
