Hello, I do not have the same problem as some people who hear a noise when they try to prime but nothing is sucked I'm like there is not even noise for example on my 3 other pump you see the little thing turn in the middle and it sucks and bah on one of the 3 it does not even turn and it does not suck, thank you for your answer.
 
You can record a video of that pump head when it's working, technicians will check.
Send video to info@chihirosaquaticstudio.com
And attach a screenshot of the Device ID number and Firmware version.
Finally, the problem was really with the pump, the dealer is going to send me a new one. Thanks for your help! Buuut I've got another little problem with my aquascaping: my chihiros A2 MAX 120cm ramp is starting to flicker, is it because it's too hot? Indeed, when I put my hand on it, it burns even though I haven't overclocked it and the lamp intensity is at 100%. What do you recommend?

It could be a problem of the bluetooth controller.
In the app switch to Manual mode, tap the Off button, could the flickering light be turned off?
