20 Most Recent Krups XP 4000 Espresso Machine Questions & Answers


Maybe the grind is too fine and it is building up too much back pressure. Max is normally around 15 bar, more than that and the pump stops functioning. Also try another silver bucket that holds the grounds, if it is double walled sometimes grinds too small can block them between the skins. There was often a single wall bucket available that eliminated the blockage problem.

The pump is probably bone dry, you will need to put some water into it under pressure. I have a piece of hose in my workshop that fits the seal that the tank engages into, it's about 8 to 10" long. I engage the hose, fill it with water, activate the pump and seal my mouth over the hose and blow as hard as I can like I'm blowing up a balloon, it rarely fails.

I had the same problem .... My gasket split and I replaced it and water was still leaking past the gasket... Try this - Don't tighten the screen screw all the way...I have mine set at about 6 turns counterclockwise from fully tightened. Loosen the screen screw more if needed until the leaking stops... As a result, the gasket will sit lower and make a better seal with the portafilter lip.

Try running 2 cups of white vinegar into it and run it for two cycles

I had the same problem. The issue was that the machine needed a clean to dissolve Calcium build up from the water. I used a commercial cleaner available at my local supermarket but have since used white vinegar and get just as good results. I just put about a cup of white vinegard in the water haopper and run the machine without the group attatched. I run the steamer wand and then put another cup through with the group attatched . I then rinse a few times with fresh bottled or distilled water.

Check the grind on the coffee or the packing pressure used to tamp. If it flows great without coffee in the portafilter, then the problem is the grind or tamp. The grind might be too fine that the pump has to use so much pressure that the relief valve open and most of the water goes into the drain tray.
