Jacuzzi J-340 troubles

Hi everyone, Iím new here and hoping someone can offer some help because Iím stumped.
I bought a used Jacuzzi J-340 this summer and after fixing all the freeze damage and replacing the circulation pump, I finally got it filled up and running. I started getting a FL1 code which I learned was due to the flow switch being stuck open. I adjusted the switch and got it to connect when water was flowing. Everything worked as it should for the first day and it heated up to the proper temp. Today, I woke up to find the display read 41.0. And nothing would turn on. The hot tub displays in Celsius so I assumed this was the temp which was higher than I had it set for.
I shut the tub off at the breaker and let it cool down. I flipped the breaker back on after it had cooled down and everything worked again however the temp was not accurate. It heated up for a while and then I started getting the FL 1 code again then the display went back to 41.0. and everything shut off. Now nothing will work. Iíve tried restarting it but it makes no difference. Nothing will work. Ive ordered a new flow switch and a new temperature sensor. I donít know if that will make a difference. I see no kind of damage on the circuit board so I donít know what to check for or try next. Iím hoping it doesnít need a new board because itís already cost a lot more than I was hoping. Any help would be greatly appreciated. Thank you.

Solved!

Today I noticed a crack in the topside control. I thought some water might have gotten in there so I removed it and dried it in rice. Problem solved! Everything works as it should now.
