Hi,
I own a focus temp 105 000 BTU heater for my inground pool. The fan and the unit is operating. However, the unit produces hot water for a 1-2 minute then shuts off and does not reach its desired water temperature. Are there any solutuions?

I have series heat pump insta 55 series and it stop sending warm waterin the pool no matter how high I set it... what can be done here to get it going ?
