How to Fix / Troubleshooting
Safety first: No immediate plumbing disassembly is required. Use caution when changing installer settings.
Step-by-step:
- 1. Confirm resin volume: Check the AquaHouse model label for resin tank size (e.g., 30k, 45k grains) and ensure the programmed capacity matches.
- 2. Verify hardness and usage: Re-test water hardness and compare daily usage to the controller's assumptions. Adjust settings accordingly.
- 3. Perform a manual regeneration: Force a full regeneration and test softened water hardness afterward. If hardness remains high, the resin may be exhausted or fouled.
- 4. Inspect for iron or fouling: If your water has high iron or manganese, consider cleaning the resin with an approved resin cleaner following AquaHouse guidelines.
- 5. Replace resin if needed: If performance does not improve, the AquaHouse cation resin may need replacement.
