Possible Causes
Internal blockage in the Kripsol heat exchanger, Debris caught in the Kripsol heater inlet screen, Partially closed isolation valve near the heater, Collapsed flexible hose in the heater circuit
How to Fix / Troubleshooting
Safety first: Turn off the pump and power before disconnecting any plumbing. Relieve system pressure by opening a filter air bleed.
- Check valves: Ensure all valves before and after the Kripsol heater are fully open.
- Clean inlet screen: If your model has an inlet strainer, remove and clean it thoroughly.
- Inspect hoses and pipes: Look for kinks or collapsed flexible hoses in the heater loop. Replace damaged sections.
- Backflush exchanger: With the heater isolated, connect a hose to backflush the Kripsol heat exchanger in the reverse direction to dislodge debris. Severe blockages may require professional chemical cleaning.
