The Aqua Comfort heat pump pool heater may remain in the "OFF" position after selecting the POOL option due to the following possible issues:

1. Broken or faulty temperature sensor – The system may not detect the correct water temperature.
2. Incorrect automatic timer settings – The heater may be scheduled to remain off.
3. Low water flow – Possible causes include a dirty filter, closed valves, pump not running, or air leaks.
4. Dirty or corroded heat exchanger – This can prevent proper heating.
5. Electrical issues – Weak or insufficient electrical connections can prevent operation.
6. Sensor or wiring faults – Error codes like “tSO” or “tSS” indicate problems with the water temperature sensor connection or wiring.

Checking these areas can help identify why the heater stays off.
