Heating problems

If the control system thinks that there is not enough water flowing through the heater to heat the spa safely, it will shut down power to the heater, and you'll most likely see an error message on the display screen. Different systems use different messages, but some common ones are FLO, FL, LF, dr, drY, PS, FL1, FL2 or Err1, depending on the model of the control system installed.

You turned your spa on yesterday, but the water is still only lukewarm, or even cold? You might have a heater problem, but other - often more simple - reasons can also be the source of the problem. We'll explain, step by step, how to identify the cause of these malfunctions.

The Astrel Easy heaters are available in several versions, depending on the power, the type of flow detection and the sensor model installed on it. All references start with "PFEAR" and end with "00000" or "00001" (the last digit is not important). The three digits after the letters PFEAR provide the essential information on the heater configuration.
