If also have Yocan UNI vape mod flashing error, similar with this Yocan user, please read this thread.
I bought the yocan box vape maybe 3 weeks ago. It charges, it heats up, lights flash, but I can't get vape from it. So far I'm not finding my issue anywhere. Please help.
Thanks for contacting us.
How many times does the light flash when you hit the fire button?
The battery flashing 5 times means no atomizer error, the Yocan UNI battery can't detect the vape cartridge.And the UNI battery flashing 3 times means short-circuit error.You can try to switch the vape cartridge or loosen the adapter.
