Problem with Qca Spas Jewel Series Topaz Plus Hot Tub

QCA Opal hot tub display reading OH.

Was starting to empty tub for routine water change. Noted that discharge water was cold. Water in tub warm (90's) display reads OH. Disconnected tub power, reconnected (stopped emptying tub water too) Tub cycled through jets, bubbles, now circulating, heater light on, 82 degrees. What happened? What do I need to do about it?

The tub experienced an overheat situation. This may be due to leaving the t stat turned all the way up and not monitoring or the hi-limit sensor is defective. The hi-limit sensor will shut down the heating cicuit if temp gets above 105 D optimally.the fact that the heater light is on is a good sign that things are working at this point.Whether or not a suitable temp(100-103 D) will be arrived at is to be seen. If spa heat kicks off before set temp is reached then replace hi-limit sensor.
