Drips significantly once you turn it on. I have to put a cup underneath it while I'm waiting for it to heat up. A few times I have forgotten and there is a drip tray full of espresso and splattered all over the counter by the time it's ready to turn it to brew setting. This unwanted seeping has to make the actual brewed espresso weaker.

I've even tried doing the maintenance cleaning as directed on a regular basis to see if removing any residue buildup would fix it but there has been no noticeable improvement for the issue.
