    It is definitely possible - and probably worth while every few months. I usually just take off the top burr and dont bother with the bottom one - its just too much hassle.

    If you have been using it for a while and have never cleaned it - get ready for the smell. Its a wonder something that smells so good fresh can smell so bad after a few months.

    IRT cleaning of our grinders regardless of the brand have any of you tried using a high pressure air gun to clean your machine?

    We use one on ours and at 120psi there is nothing left, We pulled our grinder down and found the internals to be very clean. Just a thought

    FB,

    I cleaned my Rocky over the weekend. Gave it the once over with a tooth brush, then hit it with the air gun. As good as new, not a speck of coffee left.

    Not wishing to tread on anyones toes but some in the service game will advise that high pressure air is good for some things and not good for others.

    In the case of a grinder, high pressure air may well clear out the grinding plates/burrs and the small channel through which the grinds pass on the way out, but it may result in grinds ending up in places where it shouldnt be such as underneath around the motor and wiring where it can cause other, future problems...

    I find the best tool for cleaning / clearing the grinder from time to time, to be a common vacuum cleaner. Every workshop should have one. So instead of blowing grit into places where it shouldnt necessarily be, you suck the garbage through to where you want it to go!

    And yes by all means unscrew the top plate and suck it out using the vacuum cleaner and an artists brush, but beware that it is relatively easy to cross thread the very fine thread when trying to screw the top plate carrier back on. Take care.

    Regardez,

    Youre right of course, you dont want coffee grinds going into places they arent meant to. I pulled the top burr out and cleaned it away from the machine. Then loosened the grinds on the bottom burr, tipped the machine on its side and blew into the centre of the burr set, sending the grinds out and away. I think if its done right, this is the way to clean it.

    Hi,

    Much prefer the Vacuum Cleaner method. Does an excellent job and the grounds end up in the bin. Coming from an electrical background, I wouldnt recommend using high pressure air to clean out Rocky unless you were an accredited service agent and had Rocky completely disassembled for a major overhaul. Based on nearly 40 years experience of maintaining electrical equipment.

    Cheers,
    Dimal.

    I agree Dimal

    As a Registered Sparky opening an electrical appliance with out the necessary training is never advisable.

    A Vac is the safest option by far and I doubt you would taste the Difference. But when it comes time to change the burrs Id be going to an Autheorized service agent.

    Tho over here in Ausie even they dont need any qualifcations. At least in NZ you need limited registration to do the job, so at least there you can be sure that the person servicing your appliance has a basic idea whats going on.

    Cheers

    Re: Cleaning Rocky??

    I agree with what you siad Rich, however a lot of common sense also prevails. We certainly do take the top off our grinder, and after a quick brush down the Air gun is used to blow out anything that we cant get to, with this in mind you have to remember that the top of the grinder is off and as the air is blown in from one point there is certainly a large enough area for the air to escape. Grind certainly do find their way into areas that we best not speak of, but if you do it carefully and use some nouse the job is a good job. You also know that dust a not a real major problem with a lot of electrical gear, but it does stop many components from cooling effectively, and most grinders would have a sealed bearing at the head and it would take an awful lot of pressure to force the grinds down this area (alowing for the fact that if the compressed air has somewhere else to go instead of down the shaft)
    I also agree that many repairers here are not accredited sparkys and thus you are faced with the problem of do I send it to someone who knows bugger all and face the chance of them stuffing my machine up or do I do it myself (that is if your techicaly minded)

    But then again we are all faced with little delemas in life, it is your own choice as to whether you wine away in the corner or do you boldly face the world and do what you think is best, No one disrespects someone who gives it a go compared to someone who runs away. (Not having a shot at anyone, just my own little interpretation of life)

    Hi FB,

    Agree with your sentiments. I wasnt concerned so much about grounds getting into the bearings but getting into the motor winding itself. As you say, this then has the potential to cause blockage of air cooling galleries in the motor stator.

    Also, Im not sure what happens to coffee grounds over time as to whether the resultant rancid oils and other compounds might become corrosive? I know a lot of foodstuffs can do so.

    Even though I no longer work "hands on" in the industry anymore, Im still lisenced and as such, must be seen to be providing advice that recognises the potential for mishap... even via the Internet.

    Generally though, given the option of either method, I would always go with using a vacuum cleaner rather than blow air in and around the machine, its much safer and doesnt spread contaminents to all corners of the immediate environment. Also, most people will have a vacuum cleaner handy but might not have access to dry compressed air and a suitable filter booth.

    Cheers,
    Dimal.

    Re: Cleaning Rocky??

    Guys,

    I dont think its an issue really. Perhaps I am lucky but in my own area most *independent* repairers are either licenced sparkies, or have done the electrical appliance repair course at Tafe. They are trusted to repair espresso machines for cafes, or autoclaves at the hospital. They are usually quite experienced and repair a multitude of different appliances.

    Workshops run by the agents / importers of espresso coffee making equipment employ people with specific experience in that field, and train their own "apprentices", in a field that has no specific qualifications. As far as I know the only thing you CAN do is do the electrical appliance repair course at Tafe.

    This does not preclude the fact that these people become specialists in their field.

    In my experience very little goes wrong with a coffee grinder, and when it does its seldom electrical. If someone is in there changing over grinding plates, they dont have to go anywhere near anything electrical.

    Some electricians I know who spend their lives wiring houses or working on building sites or in "industrial" applications (rather than working on "electrical appliances") wont go anywhere near an electrical appliance, its not their field of expertise. Its not that they dont have the capability, they are simply not interested.

    So you see, there are horses for courses and you dont necessarily need to be an electrician to repair a coffee grinder, and you certainly wont wreck someones coffee grinder just because you do not have an electricians certificate, particularly with the most common breakdowns.

    Perhaps the worst thing you can do if you are attempting to repair a coffee grinder, and you are not a licensed sparky or someone with the requisite knowledge or experience, is to electrocute yourself!

    Just an opposing opinion.
