Aquacal Pool & Spa - Recent Questions, Troubleshooting & Support

Sounds like a bad temp sensor or switch. Like in cars my guess is that the switch is failing to work causing the fans to stop despite the pump getting hot.

go to system set up then go to calibrate and change temp

overheated check gas pressure if not enough it will distort heat exchange

Contact a pool supply store or the manufacturer for manual. If you need further help, reach me via phone at https://www.6ya.com/expert/frankie_091f536560a54e12

I looked up the users manual for this unit and it said if the display was not working then "ensure the main breaker (located at the power supply panel) and the disconnect switch (located near the heat pump) are both turned ON."

If power is truly comming into the pump then the problem is likely either a bad power supply, connector problem or the display board. There could also be a fuse blown but that would likely be caused by a bad power supply.

I am not sure HeaWave will help but I recommend you call the HeatWave technicalsupport at 800-786-7751 and they might be able to help you figure this issueout. I hope this helps.

Please vote on this answer. Thank you.

contact your pool service provider if you have one or find out where the installer got that heater from they will carry parts or a new heater..
