Question about Krups XP4030 Espresso Machine

No water flow even though descaling

The machine won't pump put any water, either from the head or the steam nozzle, no water comes out into drip tray either. I have tried descaling but cannot get water through with this process either. It makes all the sounds it should do however.

I KEEP having this problem... everything is in place, but no espresso. Nothing comes out the brew head. I have found multiple fixers for it. One: make sure you have water in the tank and that the tank is firmly pressed down (this was the most embarrassing of the mistakes I made), Two: try a slightly courser grind of espresso. On my Black & Decker burr mill, I have it on the 3 (of 12) to finest settings. Tamper only a little bit... not too hard. Three: when the flow is just not happening, try running some steam through the nozzle to see if you can get things moving along. Once I ran the steam through... it sputtered and coughed for a few seconds then steamed normally, then cooled it back down and the espresso came out fine. This was the most recent fix.

This may sound like a silly solution, but this happens to me a lot too, and this is how I fix it.

Just check the water container. Lift it up, and put it back down. Then, make sure it is really locked in, so press it down some more.

I know this sounds ridiculous, but the same thing happens to me ALL the time.

Hope this helps.

I started the descaling process as according to manual. I tried running water through every 6 hours or so, however it kept coming up dry. I left the water in for a total of 2 days before finally the water managed to come through.

You can try this different approach: open up the back of the appliance, and blow hard into the rubber hose that comes out of the water reservoir and into the pump, _while_ the machine is on and in espresso mode. The machine starts coughing, then water flows. You might have to fill the pump hose with a little bit of water.

    dont forget to descale after you get the water through - the machine will likely clog again in a few days

When I turn on the steam valve, nor hot water nor steam comes out (not one drop), it doesn't make it to the nozzle and instead it goes directly to the drip tray. Coffees dispense works...

Hi, sounds like either you have a blocked or fauly solenoid, or micro switch or the water inlet side of the boiler is bocked. This is easy to fix. You need to be able to get to the inlet on the boiler, undo the water line and drill it out using a 3mm drill bit. Dazza

(Button 26 is the right-most one (2 intersecting
From the Manual:
Press the button (26) for at least 5 seconds to
select the descaling operating mode; the LED
emits a fixed light.
• Direct the steam nozzle (14) toward the drip
• Position a vessel of adequate capacity under
the steam nozzle and turn the hot water knob
anticlockwise (16). The appliance starts an
automatic descaling cycle with pauses preset
by the manufacturer and managed
automatically by the appliance.
• At the end of the cycle, the flow of the
descaling solution is shut off and the 5 buttons
start flashing simultaneously.
• Turn the knob of the hot water nozzle (16)
clockwise to OFF. In this case, also the warning
light (27) flashes.
• Rinse the water tank and fill it with fresh
drinking water.
• Position a vessel of adequate capacity under
the steam nozzle and empty 2/3 of the
contents of the water tank by turning the steam
knob (16) anticlockwise; to shut off the flow,
turn the knob (16) clockwise.
• Let the appliance heat up and empty the
remaining contents of the water tank by turning
the steam knob (16) anticlockwise; to stop the
flow, turn it clockwise.
