The water outlet may be blocked. Try inserting a skewer up it to dislodge any residue. I would call the Lavazza customer service. If they can't advise you, ask them if they can replace the machine. I've found them to be reasonable.

Our machine does this too, since new. I am not sure why but it has never affected the operation. I just empty it after use.

Thank you, but ours has just started to do it after 6 months.....we have just descaled it to see if it makes a difference....

Hi, mine does too even I after I descaled it. It's not a lot so I just empty it out with the capsule and it doesn't affect the operation. I've just purchased a re-useable stainless steel capsule so I'll post how that works out too. Hope it goes well and I don't have to purchase non recyclable capsules again!

I will have to get back to you on that one i have never measured it.

It’s ok, I found out the answer in the meantime. Unfortunately the total amount of dispensed coffee is the entire capacity of the water tank! So there isn’t a way to preset it to stop after a cup of coffee. It only works with an ON/OFF button for making coffee and you have to watch it and stop when you have enough coffee in the cup. This is very impractical in busy environments where not everyone understands that this is the process, most machines on the market dispense one coffee at a time, so it leads to spillages if people don’t figure out in time how to stop it or are walking away from the machine whilst it’s making the coffee. Very bad design, I guess that’s why Lavazza now brought out a new model called A Modo Mio Jolie Plus . This new one has a preset small/large coffee function ( 2 buttons) which can also be adjusted in volume to suit your own cups.
How could anyone bring out a machine that literally pours 600ml of coffee in a tiny cup unless you’re watching it and stopping in time??

We like small espresso coffees so this machine is perfect for us. You do have to watch the amount coming from the machine. We usually dispense around 50ml per capsule. I understand the machine turns off by itself after 90ml. But I think the coffee would be very weak with that amount. I don’t think it would be much use in an office environment where people want a large serve and aren’t prepared to put in a little effort to make a perfect coffee. We’ve been drinking Lavazza coffee for nearly 40 years and it’s still our favourite.
