Thread: Jacuzzi J-365 flat line
04-01-2014, 04:37 PM #1
We shut off hottub bc water was too low and went to fill it next day and was empty. Flo control cracked and a ozone in a line was broken. Replace flo control, remove the ozone part and replace the line. It was working fine for a day and then flat lined on display.
- - - - - shut off power and restart it doesn't get rid of it. Any suggestions?

Is the heater very hot to the touch? Watchdog (the four dashes) is intended to come up and shut everything down because the high limit sensor on the heater has detected a temperature of 118 degrees. It could be that this sensor has failed or your heater is really getting very hot. Was it the Flo Switch that your replaced? If so make sure that is plugged into correct postion at the circuit board. You may want to call service with this type of issue. The service techs have test plugs to determine if the sensor is causing or the circuit board.

I think it tech time, can't check the heater if I can't get it on. I replace the flo switch but used the old wire, I have a different square end that is hard to find.

If the Flo switch is not working properly and your circulation pump is not coming on it could allow the heater to come on and get very hot then shut down with the four dashes. The flow switch is intended not to allow the heater to come on if the circulation pump has a problem so it wont dry fire.
