Customer Feedback

‘After spending money on several cheap quality coffee makers, I decided that I needed a machine that could produce better quality brews. After an extensive amount of research, I had the ECP3420 on my shortlist and so I decided to give it a try. Although it's less automated compared to many $500+ models, I'm happy with it so far, especially when I consider its low price and the high-quality coffee that it brews.'

‘The clearance between the dispenser and the base is pretty impressive. I was actually looking for one such model and I'm glad that I finally got it. Also, the single and double size variation is what I love the most about the De'Longhi ECP3420'

‘I have been using this machine since 2011. For middle-ranged users, I think this is a good one. I use it almost daily and drink roughly 10-15 cups from it every week. The steamer power is good, and the pump is still strong after these many years of use. My only minor complaint is the startup time which has recently become a bit slower.'

  1. I was giving the ECP3420 model as a Christmas present in 2019 to replace a small expresso maker, which was on its last legs. There is a learning process to adapt from the old expresso maker to the Delonghi model. Also, adjusted to the amount of milk to froth and amount of heat. Once I got the hang of monitoring the amount of coffee being poured into a mug and frothing the milk, I truly enjoyed over a year’s worth of tasty and frothy coffee. What I didn’t learn early on is the process to descale the expresso maker. I first encountered problems getting coffee to pour out due to a clogged filter, which the Delonghi FAQ suggested to clear the filter wholes. It was around 6 months before this happen. Second issue I encountered was water leaking from under the expresso machine. Again went to the FAQ and other sites, which pointed to the water tank plastic rings were not tight or needed to be replace. I got so tired of the water leaking under the machine that I had to pull the water tank out after each coffee cup. Finally, I realized that I needed to descale the machine, which I was able to successfully but it seem to make things worse. Steam started to seeping out from all parts of the machine, the steam pressure was uncontrollable and couldn’t get a good cup of coffee without dealing with the leaking and steaming. Delonghi should emphasis descaling of their expresso products. I’ve learned a lot about these expresso machine and look to purchase another Delonghi expresso maker and take better care of it.
