As one of the only repair centers in the US for the infrared saunas which originate in China, we have been repairing these control systems for more than 10 years.
Based upon my experience, there could be several reasons for this.
The most likely would be that the temperature sensor has either become unplugged or a mouse chewed through the wire or it has failed.
If these are not the issue, it will be internal to the control pack itself and it will require a technician to evaluate and repair it.
We rebuild the control packs for most manufacturers. You can call me at 1-66O-263-O984 to discuss your options or to order components.

Question edited for clarity, 'till' refers to turning over soil, 'tilling', 'until' is the word you need.
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.

It appears to be a New Zealand product made in Australia. We are in North America. This link should find you one and also has a link to the maker.
