  • A rock killed my 14yr old Rocky, what's a good replacement?

    Hi all,
    Sadly my faithful 14yr old Rocky accidentally swallowed a rock the size of 2-3 coffee beans and died. A few questions
    • my brief research led me to Compak K3T as a replacement. is there a better option in this price range and level? I am trying to avoid anything too smart like a digital timer or something. I think the simple nature of the Rocky was the reason that it went for that long.
    • any store in Melbourne that would have stock?
    • I have had small rocks in my coffee beans before, but nothing this big. Anyone had similar experiences? Any good tips on avoiding rocks in grinder issue? I obviously don't want the new grinder to suffer the same accident.
    • Does the roaster have any responsibility, I know it is kind of part of the deal, but a rock big enough to kill a decent grinder surely is a risk that needs to be managed.

    Thanks in advance

    Welcome Joseph...

    In saying the Rocky has died, what do you mean by that exactly?

      Two thoughts
      1) Checking for a rock is routine for me, even though I rarely find one. I did find a 5/8" Whitworth nut once when I changed roasters (briefly)! Check out Andy's thread about the crap he gets that he removes with his destoner (and magnetic?) system. Perhaps you should look before you pour the beans into the hopper?
      2) I always thought that my ceramic burred Mahlkoenig Varios did not need their special $4 plastic gear which is designed to strip and then be replaced before anything else gets damaged. Now I see the Swiss Ditting factory (which actually makes the Vario) were way ahead of me.

        There's something to be said for a "rock" solid grinder with a minimum of electronics. Larger and probably not as aesthetically pleasing as some, the K3 will still be going strong when most others ($450-$550), are a distant memory. Mine's 10yo and just about to have another burr refresh. I have the timer (Touch) model but have always used it like the Push model. You could save a little money if you don't want the timer function.

        If you shop around and wait for discounts, there are some really good deals on the Compak K3 available.

          I cleared the remaining coffee beans and found to rock in the burr. I was hoping the rock was just jamming the motor, but it still didn't work with not blockage.
          Looking a the parts diagram, it will either be the motor or the capacitor. If it is the motor, it is not worth fixing based on parts price I found online. If it is just the capacitor, then, maybe, but how do I check?

            Have never pulled the motor out of a Rocky (never needed to) but it is entirely possible that there is a Thermal Overload Protection Device installed that may only require resetting. If so you will, at least, probably have to remove the bottom cover to see if you can get access to a Reset Button on the motor; if nothing is obvious there, you will probably have to remove the entire motor and look for a reset button elsewhere on the motor.

            Doubt that Capacitor has failed, in isolation, as you would still be able hear the motor trying to start without it. It is also possible, that there is a remote protection device between the start button and the motor system and it is this that will need to be reset. If you're not happy doing any of this, you should engage the assistance of a coffee loving Sparky to suss this out for you.

            All the best,
            Mal.

              If you're in Sydney and don't mind travelling out Liverpool way I can take a look for you

                Shouldn't be a cap, as they are only a start cap. A pool pump shop will be able to test it/supply another- you need a special cap tester.

                But your nose should tell you. If it smells cooked, something is burnt. Smell the cap and look for damage, same as the motor- look and smell. If its not smelling cooked, in sure it will be a overload somewhere, or a over temp...

                  Attach the parts diagram, perhaps the overload points are easy to single out

                    The diagram is easy enough to find online and sure enough there's a circuit breaker in there. First place I'd look, just check to see if it's open circuit.

                    BTW the cap looks like a run cap, not a start cap. Some run caps have class P2 protection (fails open cicuit) but I don't think this is one.

                      Just located an official Rancilio Parts Manual for the Rocky (attached)...
                      There is indeed Overload Protection within. It is Item#24 located close to the base of the Grinder.
                      You will have to flip the base cover open and reset the Circuit Breaker, probably by pushing a small button.

                      Once this is done, all should be good to go...

                        14 years is a great innings from a grinder.

                        I reckon the OP has well and truly earned the right to treat themselves to a new grinder!

                          Just noticed (must be getting old) the irony in the thread title - " A rock killed my Rocky".
