Customer Question

I have an old Jacuzzi Z115 Hot tub. Six months ago I replaced the Board, Hi limit sensor, water temperature sensor, and new filter. Last week I put in a new pump. So basically everything is new. I refilled the tub and when the water comes up to temp, the system shuts down and the LED blinks steady. I can shut off the breaker, let it set for 15 minutes turn it back and and it does the same thing. I am at a loss. Any ideas?

Have you inspected the pressure switch?

It's 6 months old. That was replaced along with the other parts.

what led light is blinking?

Customer: replied 12 months ago.
The only one on the unit. there is not LCD read out. Just a LED next to the temp knob. It blinks steady after the system shuts off. I removed the Hi temp sensor from the heating element tub and system will run fine now, but the heat status led does come on. I am assuming its not heating due to the Hi limit not being in place. Sounds like that might be my problem.

I thought you said you had already replaced the hi temp sensor?
