Posted Sat Dec 29, 2012, 12:58pm Subject: New rancilio rocky with grounds falling out the bottom?
Just got a rocky as a gift for xmas and have not used a higher end grinder. After grinding about 6-7 cups I noticed that there was a large pile of grounds coming through the bottom and when I unscrewed the bottom, there was a fairly large collection of coffee grounds in there. is this normal? Could not find help online searching

Hi and welcome. You really are not giving us much to work with, you said 6 or 7 cups, is this shots of espresso or cups of coffee? Are you making espresso? Is it a Doser or doserless grinder? What did you unscrew? How much is a large pile, and how much is a fairly large collection?

Ground about 6 cups for coffee (17 g each) using medium roast beans, set at 20, with a doser. So not many beans have been run through it. I noticed a few flecks of bean at the bottom of the unit. When I moved it, a stream of coffee grounds fell through the perforations at the bottom panel. I unscrewed the 3 screws and there was a substantial pile of coffee grounds there, probably about 3-4 tablespoons. As this is the first larger grinder I have ever tried (have used my hand grinder previously), I did not clean the chute after each grind, and I did notice that the chute would be completely occluded after each grind. I assumed that the momentum from a new grind would simply push out the prior. Is it not cleaning the chute that is causing the grounds to fall?

Thankyyou for more info. My hands on with a rocky is limited to about 3 double shots on one, I have mostly Mazzer grinders. Are you saying that you have adjusted the Doser to about 20 g and are filling the Doser chamber so that the Doser is being used the way it was designed (they require the Doser chamber to have a high level of grounds in n it to be accurate and consistent with dosing)
It is normal for some grounds to get Inside the machine but that sounds very excessive. Was there any oil showing on the beans before grinding? That would tend to clog up the grind chute.
OK Rocky experts, now if you guys could take over and help this guy got, we both would be thankful

There is a gasket between the outlet of the grinder mechanism and the body of the grinder that's meant to stop this happening, part number 36-301-027, described as GUARN, SCAR, CAFFE'ROCKY -GM . I would suggest it's missing or dislodged by rough handling in transit, either way you should send the machine back to the retailer for repair. (Unless you're comfortable with DIY.)

Thanks for the helpful advice. I took apart the hopper and the gasket (small white soft plastic piece at chute) appears to be present. I think that my coffee may be the problem. After only 6-7 cups of coffee, there was quite a bit of soil-like buildup covering the top burrs. Looks i'll have to use my hario hand grinder for my brazilian beans. Maybe i'll have to grind rice every few cups? I'll keep the rocky as it was a nice gift from family, but I like the simplicity of the hand grinder.

I would venture to say that the gasket you are refering to is not the gasket Alan is talking about- and that the gasket he's refering to could also cause discharge problems if it were not properly in place- just a guess.
That's the one. Note that a "leak" at this point is the ONLY WAY that ground coffee can enter the machine body. The type of coffee you're using doesn't matter.

That's the piece and it is small, but was in place. It seems that coffee grounds could spill over the top of the burr especially as the grounds seem to occlude the chute. When I unscrewed the hopper the grounds had covered most of the burr.
