5. Troubleshooting
If you encounter any issues with your Waterdrop WD-10CM filter system, please review the following common concerns:
Common Issues:
- Reduced Water Flow: This often indicates that the filter is nearing the end of its lifespan and requires replacement. Ensure the water supply valve is fully open.
- Leaks: Check that the filter is securely twisted and locked into the system head. Ensure all connections in the system are tight. If leaks persist, turn off the water supply and contact customer service.
- Unusual Taste or Odor: If the water develops an unusual taste or odor, the filter may be exhausted and needs replacement. Ensure the initial flushing procedure was completed after installation.
