PCLake Posted April 5 Report Share Posted April 5 2003 Altamar tub with a control panel from another Sundance Spa, might have been an Optima. In any case, the tub had been working fine for many years, then started to get an OH code at any setting above 101 degrees and the blower/pump kicks on as per the program. The tub water reads 101 on the thermometer hanging in the water. From other threads on this site I have tried running without a filter, I have replaced the circulation pump and both temp sensors, the one by the filter and the one in the heater unit. Still the same issue. Any other suggestions would be welcome. Quote Link to comment Share on other sites More sharing options...
cranbiz Posted April 8 Report Share Posted April 8 Have you checked the flow switch? If it isn't working correctly, you will get an OH indication. Quote Link to comment Share on other sites More sharing options...

I figured that would yield a FLO notification. I will check it. Thanks. Quote Link to comment Share on other sites More sharing options...

Looks like the flow switch was the issue. Thanks for the help. 1 Quote Link to comment Share on other sites More sharing options...
