When it is just heating the heat light flickers and there is temp numbers flickering as welll. Any ideas or suggestions
OH is the overheat code.
Your spa temperature is set above 108, or your thermostat is faulty & not reading correctly.
SOURCE: QCA Opal hot tub display reading OH.
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.

your ozonator may have condensation water in it, try unplugging it and using a hairdryer to dry it out, otherwise you will need a replacement ozonator (i know where to get these at dealer cost if you need one). When replacing ozonator, make sure you request the correct plug type depending on if you have the white plugs or gray plugs that plug into either the side of your spa pack or the circuit board.
Good job on isolating the problem by unplugging each component when a circuit breaker trips. Next, your filter cycle is most likely set on constant filtration, you will need to reset it to 2-4 hours per 12 hour cycle. Don't put it in standby, leave it run in standard mode. Hope this helps,

Ken,
You need to contact a hot tub technician/engineer as you clearly have issues.
'ICE' means that the water temperature is too low and therefore the pumps will be turned on to prevent freezing within the plumbing. Depending upon the spec and settings, the heater maybe disabled during 'ICE' condition.
'ECON' is Economy Mode. If you have a mode button, keep pressing it until you see 'Stan' on the display. This will put the system back into the standard mode.
'FLO' means that there's insufficient flow of water through the heater, or non at all. 1) Check the water level - top up if low. 2) Ensure that all jets are open and flow water - if they don't you may have a pump issue. 3) Remove the filter(s) and see whether or not this clears the fault, if so clean or replace the filters.
'COOL' is displaying because the set temperature is much higher than the current water temperature.
As I mentioned at the start, you really should get someone to take a look at your hot tub. You may have a few issues that need resolving.
Regards,
Ian.
