The drum temp shows 172 does it preheat at all before tripping the error ?
On the underside power board, can you see a red Led and is it steady or flashing. If flashing count the number before it pauses and starts over…
This was the first time it made it this far in preheat. Before it was almost immediate.
Can you get to the Info panel in RoasTime that shows the fan speeds etc, and get a screen grab to post here.
What firmware and software are you running now ?
What @stuartmcknight asked about the flashing red LED is imnportant… that’s what identifies what error you’re dealing with on the power board (if the power board is in fact the issue!).

Here is the screen grab from my Info window - I suspect one or both of your Coil Fan values is on the low side or not registering at all…

Might be worth looking at the power board underneath to see if the fans are clean and free running. If your cooling tray has no ductwork it’s possible smoke from the tray is being sucked into the power board and depositing on the fans and other parts. When I used the cooling tray I had a right angle elbow to direct smoke away from the board.
If that’s not a winner then you’ll likely need spares from Aillio
The Chaf message is when the Chaff collector is removed and the the fans stop (new certified bullets has a switch to turn off the blower and coil fan 2 when you remove the chaff collector)
If the collector is not removed then coil fan 2 might be broken if it stops spinning. You can take off the motor cover (opposite chaff collector) and check the wires.
The support are off on weekends but should reply you today.

Hi Marathon0025,
Based on the serial number of your Bullet, we did receive your email and replied on Oct 18th, a day after we received the email. It might be kicked into the Spam folder. As we mentioned in that email, there are no debug logs of your Bullet uploaded to our system after June 1st. Yours is not a CE version Bullet so it’s most likely a coil fan 2 issue. Please find our reply in your emai folder so that we can arrange the replacement shipping for you. Thannk you!

That seems odd that a “chff” message would be thrown if there isn’t the hardware (microswitch?) to trigger it ? Thanks for the update Jacob on the hardware tweaks…
Matt, it was in spam. Replied. Thanks.

Hey I have this same problem/error code, did you get it fixed?
How do you know if the fan is broken/not working?
I took black cover off the other side from the chaff collector, and there was some dark chaf in their could that have been the issue? But still not working, wires and fan look fine.
You can take off the Chaff Collector and power up the Bullet while holding the switch with a pen or a screwdriver. The Coil Fan 2 (lower fan behind the Bullet) and the Impeller should spin a little and then stop. If both fans are not spinning, then you have a microswitch issue; if only the Impeller spins, then you have a Coil Fan 2 issue.
Best regards,

Is this true for all of the Bullets, or just the 200 volt machines?
Hi @billc,
This applies to the Bullets that have a Microswitch on the back of the Bullet. It’s located behind the extra hole on the Squirrel Cage.
Best regards,
Kevin
From what serial number is this switch there?
Hi @blacklabs,
I don’t have the exact number, but it should start around SN 6000.
Best regards,
Kevin
Hi Kevin
Serial - 2276, so mine does not have a microswitch. We are getting another one, an R2 in March, which, I guess will have a microswitch. What does it do and does it affect back to back roasts in any way.? When I roast more than 5 batches at a stretch, I take off the chaff collector while the machine is in cooldown stage and change the chaff filter and gasket. The Bullet does not throw any errors. Will this behaviour change with the ones with a microswitch?

Hi @cash0612
The Microswitch disengages the Fans running at the back. When the Fans are not running, the Bullets will show some error codes on the Front Panel. Since the R2 (Pro) doesn’t have a Coil Fan 2, only the Exhaust Fan will stop spinning. If you’re only doing a quick filter change between roasts which shouldn’t take too long, you can ignore the error codes; just make sure the Chaff Collector is properly installed and the Exhaust Fan is running once you’re done.
Best regards,
Kevin
