Possible Causes
How to Fix / Troubleshooting
Safety first: Unplug the spa before removing the filter or hoses.
- Clean/replace filter: Remove the filter cartridge, rinse thoroughly, or replace with a new NetSpa filter. Test flow briefly without the filter to see if it improves (do not run long-term without a filter).
- Inspect suction and return fittings: Remove any visible debris from the spa wall fittings.
- Check hoses: Straighten any kinks and ensure hoses are not crushed under the spa or furniture.
If flow remains weak, the pump impeller may be worn or partially blocked internally. The NetSpa circulation/massage pump should be inspected and possibly replaced by a technician.
