Pre Heat issues with V605?

Anyone had issues with PH stopping after initial heat raise?

First roast worked fine, went F1 to go Bac and PH started but then just stops heating and temp continues to decline. Exit all functions and try to start PH manually, nothing. Went to Cool mode and F1 to go back to Bac and it resumed. 2nd bac roast had to upgrade to get it to work. Has now happened on 3 bac roasts using F1??

looks like it gets to about 258 -275 C and then starts to decline. Only solution so far is switch off Bullet, close RT, unplug power & data. Turn on Bullet, start RT, plug in data reset PH temp and PRS to PH mode.

How long are you preheating for?
Can you pls send us a screen shot of the preheating phase from RT?

Thanks Jacob, I deleted all the failed PH phases as there was no rhyme or reason. I was in Back to Back mode and PH worked up until about 258-275 and then temp started to decline. I was aiming for a 295 PH. Time from setting F1 for B2B to temp decline was about 10 minutes or so. Then it would take me another 10-15 to reset machine and software to get PH working again, by which time temp usually dropped to 140-160.

Did you check the Info->Logs to see if there was an error code? I’m wondering if there was a power board issue e.g. IGBT over-temp. The error codes were saved to the server and are recoverable by Support.

Another question: did you use the PRS icon in RT3 to launch the 2nd Preheat? or did you use the PRS button on the control panel? My routine is to use the control panel (just out of habit) and I’ve not had an issue such as you describe.

And one more- did you see PH on the control panel when you launched the b-2-b


No error codes and I was using the PRS button on the bullet control panel, not the software version.
I used the F1 function to go into B2B and it started the PH function, but once it gets to around 258-275 C, it just started to decline in temp, no sounds, no alarms, no display.

It would only resume after resetting RT software, turning bullet off and disconnecting then reconnecting all cables.

If you can tell me the serial no, and when this happened then I can try to check the logs

Answered in our message thread, the addition of the little fan worked as you suspected.
