Why is there no espresso coming out when the pump is on?

Why is there no espresso coming out when the pump is on?

The machine is on and everything else is working fine, but when I turn the pump on, nothing comes out and I have no idea why.

"It can also be the issue of descaling.

I clean the filter, the boiler as indicated in the manual. But after 1 year (!gasp) the machine won't deliver expresso anymore.

I found that it is suggested to descale every 200 brews! So I descaled the machine and it's back, working.

Here's what I did.

Don't load any filter.

Take a container below the boiler.

Plug the machine.

Fill the water tank with 50% white vinegar and mix with 50% of tap water.

Turn the knob for the red light, wait for the OK green light and turn to the most right option (the one that you usually make espresso with)

Wait for hot water to drip, do this during the green lights for 1/4 of the water tank.

From time to time, turn the top frothing knob and let the descaler go through.

Repeat for another 3 times, and

then do the steps again with a second tank with 25% white vinegar and 75% tap water.

Finally, load a full tank of tap water to the tank. This is to wash off the descaler from steps mentioned above.

Load another tank of water if the acid smell continues.

Once done, unplug the plug. When the machine gets a bit cooler, unscrew the boiler and clean the boiler. Put it back.

Clean the frother as well.

That should be it. It took me about 2 hours. My machine was working as usual. Hope you have success too!"

If the water is getting into the de Longhi coffee holder but not coming out and the holder's round metal mesh is clear then the spring-loaded little valve in the middle of the round black plastic mesh-holder may be stuck. Take the mesh off its black plastic base and push hard on the little dimple in the middle of the base. It should give - this is what lets the coffee out of the holder and maintains the pressure to give a good crema. Clean it and reassemble.

"I know it’s an old thread but just one more thing to add. The descaling works, I had this exact same issue and followed the vinegar steps above and yes it started pumping water again without the portafilter. The 2nd issue I had was the screen on the portafilter was completely blocked so when I added the portafilter, nothing was coming out still.

To clear this, you need to burn the blockage away. Since the screen is blocked with dried coffee bits, they can be cleared by burning vs poking each hole out. I held mine with thongs and used a lighter for about 30 seconds a time and rinsed it under the sink after each time. As I held the filter to the light I could see more and more holes opening up. I repeated this until most of the holes were opened.

After doing this with a combination of descaling, it’s like I have a brand new machine.

Thank you to all who posted answers here, it really helped."

I just got the Lavazza Blue espresso maker and it brew the water into the waste dispenser and does not come out into the cup. The waste dispenser is where the kcups drop into. Anyone have any idea? It’s brand new out of the box.
