What to do if SINO SN-50 Water Pump doesn't respond when pressing the power button?
- MMichael CookAug 9, 2025
If your SINO Water Pump does not respond when you press the power button, it could be due to a low battery and no AC power supply connected. Connect the AC power supply and keep charging the battery. If this does not solve the issue, the power system may have a failure, and you should send it back to the factory.
