    They have all the manuals on line - Google is your friend

    From the manual:OH= Overheat The spa has shut down. One of the sensors has detected that the spa water is 43C (110F).
    Warning Notice: DO NOT ENTER THE WATER. Remove the spa cover and allow water to cool. At 41C (107F), the spa should automatically reset. If spa does not reset, shut off the power to the spa and call your dealer or service organization.

    From my experience in repairing mine, for some reason water has stopped flowing across the heater. If you are comfortable troubleshooting, working with plumbing and electric you should be able to figure it out. There are generally valves underneath (inside the cabinet) that regulate the flow and one may not be set right. Or, it could be a bad flow/sail switch. You are going to need to figure out why the overheat condition. But, there are things that can kill you inside. Don't fool around if you are unsure.
