OH is a standard error code for "over heat". This can happen due to a few reasons. Either the area around the sensor thinks the water is over 108 degrees (approximately) or the area where the sensor is in the pipe is hot from the outside heat or motor. OR it could be the sensor is bad. Does the water feel extra hot? Try cooling the water down and see if the error goes away. If not you may need to replace sensor.
Check your filter run time and be sure it is not on longer than needed (2 - 4 hours only needed at most). It is in emergency shut down. This can occur during summer, usually on hot tubs that are not fully foamed (foam keeps heat out as well as keeping it in). Turn down the heat setpoint also. It should cool down if you take cover off at night.
Not sure what the glow bottle is. Can you take a picture? Or is this on the led screen indicating the spa is on?
I think you need to have it on for the glow bottle to work...sorta sounds like it shows power.
I could not get the phone to work either. However, if the glo light does not come on it is probably because the hot tub is in emergency cool down period. More than likely it will come back on when water is cooler. If the problem continues your equipment temp sensor needs to be checked as well as the board and / or relays depending on the hot tub brand.
