ejjones55 Posted October 21, 2014 Report Share Posted October 21, 2014 So my '99 cal spa doesn't heat during filtration cycle. Light doesn't come on either. It will heat when jets are turned on and the heat light will come on. Found some small ball bearing type things at bottom of the spa. Related? Also had a jet pop out could be that?

Dnepr Dave Posted October 21, 2014 Report Share Posted October 21, 2014 The swiveling jets in my spa have little ball bearings. Give your jets a spin, maybe one has lost it's bearings. Dave Quote Link to comment Share on other sites More sharing options...
ejjones55 Posted November 15, 2014 Author Report Share Posted November 15, 2014 Any ideas here on why it's not heating during filtration cycle? It's getting cold out and it running constantly now on the low cycle because it won't heat to keep it at 102 degrees. Costing me money to have it run all day and not heat.

ejjones55 Posted November 25, 2014 Author Report Share Posted November 25, 2014 I adjusted the pressure switch about a half turn counterclockwise and now it heats on the low cycle. Easy fix that my spa guy told me over the phone. Quote Link to comment Share on other sites More sharing options...
