All components (save the plastic "tamper" that is awful) are very high-quality

I would recommend a more sturdy machine if you can afford it - like the Gaggia Classic as this unit seems to be made with some questionable quality components.

To steam, you need higher temperature and more pressure, which stresses the boiler and components more, causing overheating etc

Also, Delonghi really cut corners on quality and tried to squeeze too much profit by introducing cheap components.

The EC680M vibrates enough that the glass espresso cup being filled moves!
