I'm not sure if it's the machine that's slow by design or if I'm expecting too much, but it is REALLY slow to dispense coffee using ground coffee. This is my 3rd Delonghi and it is by far the slowest one I've used - in fact, I threw my last one out as the pump appeared to have lost pressure and was also dispensing very slowly. I'm using shop-bought, ready ground coffee (Illy Espresso, cafe Macinato). I've made sure that I'm not over-tamping it and still it's very slow. By the time that the pump has got to full pressure the amount of coffee coming out of the machine is down to a slow dribble and it takes far too long to finish the dispense.
Apart from that, the machine looks good and doesn't make too much noise - unlike some other Delonghi machines I've tried. I think I'm going to have to send this one back to Amazon (what a pain in the butt that whole procedure is) and get a replacement. Looks like I'll be drinking plunger coffee for a while, again. If I get a replacement and it works better, then I'll let you know.
I'd be interested to hear if anyone else thinks it's slow and what is your dispense time for a double espresso?
Edit - decided to send it back to Amazon. Used the online returns and it was impressive. Monday at 5pm, went through online returns procedure and printed out barcode labels and packed machine away in original box, wrapped in black bag and affixed labels. DHL was automatically arranged to collect machine next day. DHL arrived 10am next morning (Tuesday) and took box away. Wednesday morning, 9.45am new machine arrives. WOW!
New Machine works much better and pump seems fine. Coffee dispenses perfectly and as quickly as I expected.
Thanks to Amazon for great service and customer support. This is the first time I've had to return anything to them and it was painless.
