    Hottop trouble shooting

    Gene Cafe Coffee Roaster $850 - Free Beans Free Freight
    I cant believe Im back here asking questions about b.... roasting, but here I am. *
    Been travelling along fabuously for the last few months - great roasts - everyone very happy then whamo!!! :o I cant get a decent roast no matter how I twig roast times/temps, nor do the temp readouts indicate there is anything happening which shouldnt be happening. The beans come out of the roaster with an uneven surface and crazed appearence and some are black on the inside *:(. The damage seems to be done in the early stages of the roast but no amount of twigging makes any difference nor does changing the bean variety... all turn out the same ... very unpleasant coffee. *Ive recently cleaned the machine and replaced the filter but am wondering if a new filter will fix the problem. *I really hope a Hottop owner out there has had a similar problem and will tell how to fix it, easily. :)+
    Oh please please help me! Yeah Yeah Yeah!

    What model Hottop do you have?

    Have you replaced both filters? Also make sure the rear fan is pumping plenty of air out. The rear fan on mine stopped working about 8 or 9 months ago (new one sourced from the bay of evil) and gave me a couple of shockers before I figured out what the problem was.

    Hi Beanflying,
    Mine is a B model and is only about six months old. Ive ordereda new top filter as well as rear (but I doubt the problem is the rear filter as I replaced it only three weeks ago). I havent detected any change in the whirring when the fan is activated or increased in speed so I think its still working but Ill check that it out as well.
    thanks for the feedback.

    If you ave a thermocouple or some sort of thermometer you can insert into the roast chamber to monitor temperature then that might give you some data to go on. It will not read the same as the LED display but should give you an idea as to whether the temperature is close enough.

    The bean defects you mention sound more like they are caused by the coffee than the roaster. Try a different coffee, and in particular, a single origin to see how things go.

    You should be able to get a decent roast even if you pull the filters out completely. it will probably extend the roast time a bit, but if you are manually controlling the roaster then you should still be able to roast. With the rear filter out you will be able to check fan operation.

    Best to keep the fan speed down a bit if you remove the rear filter but do as Randy said, trying 250g of an easy to roast smooth / large bean like a Brazil or a Indian monsoon Malabar and see what you get.
