My Rancillio Rocky has just stopped working --- completely silent, almost as if a fuse has gone.  The on/off rocker switch seems ok, but no sign of life.  I can't locate a fuse, does it even have one?  I'm in love with this baby and can't believe that such a durable, industrial-quality machine has a problem that can't easily be fixed.  I'd rather not spend a fortune by sending it in to a dealer.  Please, please help me.

Thanks

I pulled my Rocky apart a few months ago. No fuse. How do you know the switch is okay? Have you tried swapping it out with a known good switch?

Here's a couple pictures of the innards of Rocky, with no fuse in sight:

Thanks for the pics, Dana.  

Good point on the switch, no I have not it yet.  I suppose I can short the circuit around the switch then plug it back in to see if it works (presuming the motor works outside of its case).  

Have you ever heard of their switches failing before?  I unscrewed the 4 screws in the top, took off the top burr to clean it, but that did not help.  As the use has been domestic, not commercial, I can't imagine one could burn out a motor like this.

How did you get the innards out?  Is it attached to the casing or the burrs, or does it simply come out with gravity once you have unscrewed the bottom.  Do I need to have serious mechanical skills and tools?

I appreciate your insights.

Dennis

I hate to sound obvious but have you checked to make sure your outlet is still hot? I plug mine into a GFCI outlet and once accidentally hit the "test" button on it thereby turning it off. Try plugging something else into the same plug and see if it works or not (a circuit tester would be even better).

Good luck!
Larry.

No serious tools required -- Just a screwdriver. I can't remember now where the screws are that need to be removed. I believe you remove the silver plate at the bottom (with the 3 exposed screws), and I think there are 2 or 3 under there that hold the stainless case in place. I do not remember there being any on the top of the case, but it was a couple months ago, and I am getting my share of senior moments now and then.

So, any progress on your grinder? Did you get it working? What was the trouble?

Thanks and good luck!
Larry.

To Dana & Larry:

Thanks for the help, guys.  "Rocky" is working again -- thanks to your suggestions and encouragement.  

The problem was at the connection to the front toggle switch inside the unit (not the kill switch on the side).  The 'hot' black wire which runs in and out of this switch was being pushed on by by a black-colored cylindrical-shaped electronic component inside the unit causing the a bad connection (the neutral correctly by-passes all switches).  The repair was simply to straighten the bending male connections and make sure they were tight again.

The way I isolated the problem was to by-pass this switch completely.  This was easily done by pulling off the black wire leaving the switch on the motor side of the switch (not the incoming black wire from the power side) and connecting it directly to the kill switch on the side of the machine (also easily done as they both have the same push-on connections).  It worked, so I knew I had either a bad switch or a bad connection at the switch.  Fortunately for me, it was a bad connection.  Getting inside Rocky was as easy as you said.  There are 3 screws on the underside that allows the entire bottom s/s section to come off.  To access the top of the machine, I unscrewed 3 screws that allow the black plastic coffee bean separator to come off.  Then peering down inside the top of the machine, I removed the 2 obvious screws (I think it was 2, but 3 a the most) holding the entire black body of Rocky's exterior casing in place.   The black casing then slipped off exposing everything (actually to get it completely off, one needs to also pull off the 4 black wires going to the 2 switches).

I really love Rocky!!!  Shame on me for almost losing the faith.  Viva Rancilio!

Dennis

You might want to mod your Rocky per this thread.

Thanks so much Dennis for posting this. I had the *exactly* the same problem with my Rocky today. Your posting encouraged me to open the grinder and fix this myself instead of paying $$$ for a repair.
Stefan

UPDATE: FWIW if somebody runs into a similar problem. My Rocky "died" again recently. This time the connections to and from the switch had oxidized. Wiping the metal with Deoxit spray easily fixed the problem.
