What to do if my Hydro-Pro Heat Pump shows 'Flow switch failure'?
- Rraymond58Aug 17, 2025
If your Hydro-Pro Heat Pump displays a 'Flow switch failure' message, it indicates there may be insufficient water flow in the system. The causes can be no water or little water in the water system. Check the flow volume and verify the water pump is functioning correctly.
