Question about Pool & Spa
Yes LOC is a standard topside lock code.
Try these common unlock codes,
Press & Hold Jet Button for 6 seconds
Press & Hold Temp Up & Temp down for 6 seconds.
Possibly your jet button is faulty i.e. it is broken internally or when it is pressed the button sticks in the on position and locks out the panel.
If those common codes don't work let me know which brand/topside control your spa has and I will get a more specific answer.

The tub experienced an overheat situation. This may be due to leaving the t stat turned all the way up and not monitoring or the hi-limit sensor is defective. The hi-limit sensor will shut down the heating cicuit if temp gets above 105 D optimally.the fact that the heater light is on is a good sign that things are working at this point.Whether or not a suitable temp(100-103 D) will be arrived at is to be seen. If spa heat kicks off before set temp is reached then replace hi-limit sensor.
