    I have the Gene with the 230V element (I live in France) but routinely get 240+ V at the socket (except in the depths of winter). I did the dimmer mod to be able to dial down the power to 1200W and also to compensate for the fluctuations of my mains supply (230-245V in a typical summer session)...

    Finally got a new heating element, installed it this morning and voila, machine working again 😀. Once more thanks for your help. cheers, Mike

    Thanks for your advice Dave. I'll get a heating element ordered and will report back with the results. Cheers, Mike

    Thanks again Dave, Well, for what it's worth, if I set the range on my multimeter to 2000kohm, I get a reading of around 120 between a heating element terminal and the boiler body. Mike

    Thanks Dave, Since the RCD trips immediately when I switch the machine on, wouldn't the element still be cold? Any other simple troubleshooting I can do with a multimeter? Mike

    Thanks for your help Neil, Did as you suggested, I don't detect any short circuit between either element terminal and the case or boiler. Mike

    Hi all, Switched on the Rocket this morning only for the RCD on the fuse box to trip immediately. Tried again and the same thing happened, the power led flicked on for a split second before the RCD tripped again. Opened up the Rocket, no sign of any damp/water leakage, wires all look ok. I...

    First crack in the Gene is very hard to hear with Brazilian beans, especially if you don't know what you're listening for. Better to roast a hard/high grown bean or Monsooned Malabar, you should hear the crack with those.

    It's supposedly 230V in France as well but I usually have nearer 240V or even as high as 244V. You really should get a power meter for your socket to rule out that variable. You can also see how stable your line voltage is (or not, in my case). I can get anywhere between 229 to 244V depending on...

    I have the 230V element and the line voltage can vary from 230V (winter) to 244V (summer).

    I've had that with Brazils when roasting at full power (1300W), due to chaff. With 250g roasting at 1200W or lower, never had any problems.
  12. Home Roasters
    Nah, 1200W is with dimmer on. I have the 230V model (I live in France), but the voltage around these parts is usually in the upper 230s and can get up to 245V! It fluctuates quite a lot such that I have to keep an eye on the plug meter and make little adjustments on the dimmer during the roast...

    Thanks for the info guys. I'm still roasting at around 1200W up to first crack, then drop the power to stretch development out and hit cooling just before second crack. For softer beans I also try 1150W. Temp at first crack is between 232 to 238C (gene readout), depending on the bean. Heat up...

    As long as you don't blast the hell out of the beans or drop them far too early, you'll get something not half bad in most cases. The fiddling with the roast just tweaks the taste to your liking and gets those little nuances out of the bean. Assuming your vent is open and not ducted, keep...

    I think the thing that has helped my roasting efforts the most has been keeping the temp under control at the start of first crack. Previously I used to have a set temp in mind and heat to that point even if first crack was underway, which could be a few to several degrees higher. It's that...

    My experience is mostly with Brazils and C/S American hard beans. I just heat up the beans at 1200W from room temp to first crack, stabilise at that temp by dropping the power down to around 1100W until 1 min into first crack, then drop the power again to 1000W (sometimes a touch lower) to...

    Thanks, the evenness is much easier to achieve with the dimmer mod, at least in my hands.
  18. Home Roasters
    I usually don't do any preheat, just whack the beans into the cold chamber and off we go. In the winter I tend to do a quick preheat to 50C cos I store the gene in the garage so it gets pretty cold (I roast in the kitchen). Don't know if it makes any difference though. I used to preheat higher...

    Here's my go with some Guatemala Antigua (El Fuego), roasted this morning. Batch was 250g, heated up to 238C with 1200W. First crack was nice and strong, starting at 13:06 and lasting just over 2 min. About 1 min into this, I dropped the power to lower the temp to 233C. Hit cooling at the first...

    Try keeping the heat on towards the end of the roast, don't drop it so much. I roast brazils to just before 2nd crack, but that may be too dark for your taste.
