1) Make sure the needle valve is open by turning it anticlockwise at least half-full-turn.
2) Switch your solenoid ON/OFF and check if you hear clicking noise inside the solenoid. Please contact our support team if you don't hear a clicking sound.
3) If you hear clicking noise, but no bubbles in the bubble counter, power up your solenoid and remove the tubing from the bubble counter
4) if the tubing is removed and you still don't see any bubbles, remove your bubble counter.
5) without a bubble counter, open the needle valve fully and switch your solenoid OFF/ON again, ensuring it is ON, and you hear a clicking noise inside.
6) You should hear a hissing noise from the needle valve at this point.
7) if there is no hissing noise from the needle valve, contact our support as we may need to perform a few more steps or just arrange needle valve cleaning repair for you.
Answers :
1) If you get bubbles after removing the tubing, please ensure your diffuser is clean or not clogged. If you have an additional check valve, please remove it to see if the check valve is not blocking the flow.
2) If you hear a hissing noise after removing your bubble counter, the check valve in your bubble counter is blocked. Contact our support team if this bubble counter was purchased from us.
