I have a Sundance Caprio which will not get hot. It runs on high and low speed, the circ pump puts out enough water to close the flow switch, and the filter is brand new today. I got rid of the Micro filter and just put in a C-8326 filter.
The red light which indicates heat just goes on for about 5-10 seconds, then goes off for about 20 seconds. The time is not exact nor is it consistent, but it is close to the numbers I gave. I can hear the heater relay click when the light cycles.
There is enough power - I have it running in the shop on a special power distribution box just for testing spas.
Can any of you Sundance geniuses tell me where to start with this thing?
Thanks in advance...
