Common Troubleshooting
If you are having problems with your CSpring One, see if one of the solutions below can resolve the problem.
| Problem | Solution |
| CSpring is not powering on. | Make sure that the power adapter is properly connected, both to wall electric receptacle and into the CSpring power adapter input. |
| Water is not coming out from the hose into the water chamber | Verify that both ends of the hose are properly connected into the Cspring and the water chamber intake valve. Make sure that the hose is not bent or kinked. |
| Water is coming out very slowly | Clean the waterpump filter, verify that the hose is not bent or kinked, |
| Water spraying our from the hose | This is normal. there is a valve with a pin hole that allows some water out from the hose to provide proper hose priming. |
| Noise when first powering on | When the CSpring is turned on for the first time, the pump will make a noise while the hose gets primed with water and gets rid of any air in the line. |

After every use do I turn off the MK2 or leave it on?
Should I turn off the CSpring Mk2 after every use or leave it on?
Based on the CSpring Mk2 manual, the device is designed to automate the refilling process. While the manual does not explicitly state you must turn it off after every use, it provides the following information regarding the power button states:
Because the CSpring Mk2 uses sensors to monitor your CPAP water level and a UVC light to keep the water clean, many users leave the device on (in the second mode with the ambiance light off) so it can continue to monitor and sanitize the water. If you prefer to turn it off completely, you can use the touch on/off button, but you will need to turn it back on before your next sleep session to ensure your CPAP chamber is refilled.
