SoftPro softener shows E17 and regeneration is skipped due to excessive water usage or capacity error.

Safety first: No special safety steps beyond normal electrical precautions are required for programming checks.

• 1. Verify hardness setting: Compare your actual water hardness (from a test kit or lab report) to the value programmed in the SoftPro controller. Adjust to the correct grains per gallon.
• 2. Check capacity setting: Ensure the grain capacity programmed matches the size of your SoftPro softener (e.g., 32,000, 48,000 grains). Incorrect capacity can cause premature or delayed regenerations.
• 3. Review water usage: Look at the usage history on the display (if available). If usage has spiked due to guests, irrigation, or leaks, address the cause.
• 4. Inspect flow meter: Clean and verify the flow meter/turbine as described for E05 to ensure accurate metering.
• 5. Resin condition: If capacity seems low despite correct settings and normal usage, the resin may be fouled with iron or hardness. Consider a resin cleaner treatment or resin replacement.
