It sounds like you have the possibility of a couple of things going wrong here. It could easily be a board issue based upon what you are saying. However, it could also be a pump issue because you are having limited success with filing the tub up half way. The best suggestion is to have a spa technician come out to assist you in determining what exactly is going wrong here.
You really have not provided enough details on the problem to help you diagnose exactly what is going on here.

That sounds like a thermostat problem. The heater should only be on when water is circulating, even if it is just in the standby mode before the high pressure jets are turned on.
Contact your installer or one of the parts suppliers in the link. It is unlikely to need a new mainboard.

Chemistry is the branch of science concerned with the substances of which matter is composed, the investigation of their properties and reactions, and the use of such reactions to form new substances.
OH Code is Overheat, so all the things you tried are not relevant. Low flow is normally the reason, too much heat build up in the heat exchanger so it cuts out.
So, the next time your spa throws you a OH, OHH or some other "overheat" error code, you know what to do. Clean or replace the spa filter, open all the jets and turn the pump on high. If you still have problems, check over your temp sensor and high limit circuits for wire, plug or sensor problems.
