Hi,

I've had my Alex Izzo Duetto IV for a couple months now, and I totally love it. I use a bottomless portafilter (Compack K3 Touch with doser), and have had some interesting extraction issues.

I was getting assorted channeling and distribution issues, so I started using the WDT on pretty much every shot. I seem to have removed the channeling, but I'm still having another issue during extraction; I get a nice, tiger striped stream at the center of the basket, but at about 25 secs or so, the stream moves toward the edge of the basket, at which point it becomes a little wobbly.

In a lot of cases, it's not really problem, as that is when I kill the shot anyway, but is that normal? Any of you have that issue?
