Aquapure 1400 No Flow error in spa mode once water heats up

[mcinlb]

My Aquapure unit seems to have issues detecting flow when the pool is in spa mode with the heater on.

It works initially, but once the water starts heating up, it starts getting no flow errors.

It seems to work perfectly in pool mode. The water is 73 degrees.

Does anyone know of a fix for this? Thank you!

Put it in spa mode without turning on the heater, does it still shut down with no flow errors?

What output % are you telling it to use during spa mode?
