    Re: Hi from a new Antipodean and some woes

    Well there is some good news....

    Firstly I have not as yet been able to find out my nominal supply, but this IS going to happen.

    Secondly I follwee the tips from Genesis care of Altura which pointed me in the direction of a dust filter on the underside of the machine. Basically I got the hoover out and hoovered the Gene. I also disconnected the Oscar from the double socket I use and performed a dry run.

    The Gene got up to temp more or less and performed a little under what I experienced in the UK. I roasted up some Malabar and it acheived 245 Deg after 22 mins and the result was a very nice roast. I am still not impressed by Genesis concession that it is very sensitive to voltage though. This is IMHO a major design flaw.

    The main thing is that I am now up and running again and can get back to roasting!!!

    I really appreciate all your input guys and I have learnt a lot from you all.

      Any heating element is very sensitive to voltage. Tis the nature of the beast.

        The gene cafe chews a pretty healthy 8 amps as it is. In the gene cafe the ramp up is controlled by the balance between Heat output and ambient temp. On most settings that people use ie 230 by the time the thermostat kicks in your pretty near to first crack.

        The only way to have a GC that was not sensitive to voltage in this way would be to overpower it to such a degree that roasting temps and ramp would be controlled by digital programs. Ie the machine set on full power would have enough power to burn a roast in 5 min.

        It would be nice to have a GC with this kind of control but It would probably require more power then the average domestic power point could give. I doubt they would sell as many roasters to the domestic market if installation by a qualified electrician was necessary.

        that said the guys with heat guns and bm get loads of control on the same power doing the same sort of thing. Where I think this comes from is not the power used but rather that the GC is not very energy efficient. The chaff collection is great but there is a lot of hot air that blows out the back of it. The trade off is that we can roast indoors in any wheather.

        Just a question espressomatic. whats the ambient temp that your roasting in I would imagine its getting pretty cold in NZ at this time of year if your doing it with a door open or on a porch etc. Ive found that it responds better to an ambient temp of above 22 deg

          Hey muppet...

          Well it might be cold for you natives but this is quite mild for us Pomms!

          I roast indoor with an extractor hood going - The ambient temp is around 20-22 Deg thanks to a Warm Air heat Pump and the humidity sits at 55-60% thaks to a dehumidifier.

          Looking forward to roasting in the summer with the higher temps as I too have found it tends to work better in those conditions.

          Thnaks for thye input

            hmm I just worked the maths out properly it actually uses 5 amps. 1.2kw/240v

              The voltage has been checked and it runs at 240v as it should, so that covers that. It is something that I am not able to fix, but hey ho.

              I have found that bean mass helps stabilse the temp somewhat as well. 250g of malabar roast a lot better than 250 of Santa Terazina. So with the normal beans I will increase the volume and live with it I guess.

              Thanks for all your input guys, I have learnt a fair bit

              Cheers
