I’m getting lots of aborted roasts. Sometimes even during preheat the heating just stops. There have been no visible errors, but I just found out how to use the ‘i’ Info icon to get the logs up. This is what I saw:
Error 32786: 3328 - No drum detected
Error 131: 512
Ambient temp is under 30C, first roast from cold. 280C preheat. It made it through preheat, then at around 160C ROR started plummeting, I checked the red LED on the induction controller board and it was flashing.
The manual suggests this sort of thing might be caused by the drum not turning easily (mainly due to front bearing issues) but the drum seems correctly mounted on the bearing and turns fine. The fan on the induction board is clean and spinning.
Nothing’s going to happen at the supplier for a week or so (Xmas break) and Aillio support have just referred me to the supplier.
Does anyone have any ideas what could be causing this?
I didn’t notice any flash count, I thought it was just continuously flashing. But I wasn’t looking for that so I will check tomorrow. I preheated to 280 and charged after it hit 285 then dropped to 282. But I’ve had it do this after letting it decide to go to charge itself, also I’ve had it do it during preheat long before it got to the set temp.
My reply won’t help, but I had a similar issue with power loss without error notification a few roasts ago. Around that time, I had to adjust my drum pulley tension due to slight slippage. Since it hasn’t recurred, I hadn’t the impetus to look into the cause, but I’ll have to find out how to pull up the logs to see if I had the same code you did.
I had my drum stop dead half way through a roast. Turns out the tiny screws fastening the pulley wheel to the motor drive shaft had no loctite so they just unscrewed themselves and let go. This was back at roast number 10 or so.
I got hold of the supplier, they got an answer from the distributor pretty quickly, sent an induction board from the East Coast, it got here in a few days, I picked up the roaster this afternoon and I’m back roasting. I can confirm that a roast that stopped half way several times and then was left for nearly two weeks then completed… doesn’t taste the best. But it was a good way to confirm the Aillio is working without risking any precious Ethiopian Ardi Late Pick beans.
I Have had my bullet for about three years now and have maintained it really well, and never had too many issues till recently.
Preheating is fine and charging is fine but once I get to between 140c and 150c I start to loose power and my roasts drop off dramatically. This also corresponds with the time I drop my power down by 1 level from P9 to P8 (not enough to create the problem)
I have oiled my bearings and aligned the drum pulley to eliminate a squeak, but the problem persists.
No clue why it’s happening. But I’ll speculate some electrical feedback from the drum drive motor is missing in order for the Bullet to know drum rpm. Assuming the drum is rotating (??), the easiest issue may be a loose connection to the wiring under the fixed cover at the rear of the bullet… ?? Loose connections seem unlikely after 3 yrs successful use but it’s a place to start. The dealer where you bought the Bullet ought to be able to guide some troubleshooting.
Thanks for the feedback @bab, I made sure all my connections were tight when I aligned the pulley. I also pulled the drum out to ensure there were no obstructions.
I have raised a ticket, so hopefully I will get a resolution soon.
Yeah, I find I get some fall off, but it is sort of during what I now call the “steam” phase, and this is when the beans are letting off water and beginning to white and yellow, and it appears the steam could be cooling the roast down. I notice the exhaust smell goes from a nice dry hay and cookies /biscuits to a wet and smoky smell. But I see a what looks like a “power falloff” but is perhaps an airflow issue causing steam build up. Because the “power” picks back up closer to FC, even if I am at P6, as this is when things begin to dry out a little more. But it is just temp swings that seem to be more related to letting off moisture.
