I recently purchased a Chihiros Co2 Regulator Pro for my aquarium. Setting it up, everything seemed fine and there were no leaks of any kind. However, after a week, the solenoid no longer seems to be working properly, leaving the Co2 to run 24 hours a day. It clicks correctly when the Solenoid is turned on and off, but the bubbles just keep coming. Additionally, I checked for leaks, but everything else seems fine.

I was uncertain if the steps of taking apart the solenoid from other posts on this forum applied to this particular model. Should I take the solenoid apart? Or is there anything else I can do?
 
Chihiros CO2 Regulator Pro regular or limited edition?
Remove the bluetooth controller cable, plug in and out the power adapter, see if the solenoid valve works normally.
 
I bought it on the 7th of August from the dealer's website (dealer's name is in the screenshot), but as I mentioned above it was only in operation for little over a week ago. Below is the screenshot you requested. Thanks in advance!

If the problem persists after removing the solenoid controller, it may be a problem with the solenoid valve.
You can ask the seller to replace the part within 1 year warranty.
