My hot tub will stop heating every once in a while and where

Customer Question

My hot tub will stop heating every once in a while and where the temperature is displayed, it will say "cool flo". The tub will still run, but won't heat. What's up?

Hello,
It appears a flow/pressure switch is not activating. When this occurs...is the pump running as it should?

the pump is running as it should. All jets are working.

The code is saying we are 20 f cooler than what it is set for.
This means the heater is not coming on...which the flow switch would be the first item to check
