OH anf f3 codes on a master spa

[mopar383]

Ok guys you are always a big help here is my latest. Pulled the cover up today and it was displaying OH I found out thats means over heat. I thought maybe plugged filter. I pulled it and turned off the breaker then back on.Hit the button for the pump F3 appears but the pump dose come on and runs. The hot tub works but wont shut off. Whats your ideas?

You are probably in the programming for the filter cycles, reboot the spa and see if that clears it.

I shut it off over night. I restarted it and sat the temp at 100 it just keep  heating up past 100. The pump and everything still works. When I hit the button for the pump f3 still appears but it runs as normal
