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.
