I moved my cal spa 2200. when I hooked it up again everything seemed to work. I noticed the bubbles that normally accompany heated water from the bottom of the tub were weaker than normal. I changed the Ozonater cartridge and attempted to restart the tub a couple of times. The bubbles and heated water have stopped all together. The heat on light is lit, the ozonater light is lit, there are no error lights, but the tub won't heat. I've spoke to several people at Cal Spa and their lost. Any idea's.


Thanks,

Try removing an airlock.

I did remove the airlock and the system now bubbles again. However, I still don't have heat. Can I assume I have a flow switch or heater element problem?


Thanks,

Make sure the heater element is getting voltage, to check this put one meter test lead on each electrical terminal of the element and see if you have full voltage. You can check the flow switch, it should read closed when the pump is in low with your OHM meter.
