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.
Some have a electric heat element, while some others have a "Exchanger" system utilizing the heat from the pumps motor to transfer that heat to the water. Pump will be on a lot!

Check the Topside Panel Display to see if the "OHS", "OH", or "SPA TEMP
LMT" Spa Water Overheat Error Message has Cleared. If the Error Message
has Not Cleared, the Spa Water is still too Hot to Continue Testing. • Either Wait for the Spa Water to Cool Below 108°F (42.2°C), or Exit Now and Retest at a Later time.
