Thread: Cal Spas CS7000 No Heat
08-15-2013, 03:50 PM #1
I have a 2003 model Cal Spas CS7000 and the heater is not working. The ohm reading on the heater was 10.5 Ohms. I am not getting 230 volts to the heater. I suspect that the problem may be in the circuit board. Since this is an expensive item, i would like to do some more troubleshooting before I purchase one. This model has two "tape on" temperature sensors, but they are difficult to troubleshoot as well. Can anyone help?

The element is in range so that should be good. If you spa has a light or indicator on your topside panel when heater should be on make sure that indicator is lit. If it is on and no power to heater then it sounds like the circuit board. If that indicator is not coming on then it could be the sensor causing it. I would also try removing the filter and see if the light will then come on if it isn't, a flow problem can also cause a spa not to heat.

Yes the "heat" light is on on the topside controls. I just cleaned the filters last week, but did remove them just to test the flow, still no heat. I wonder where a person could find a wiring diagram or schematic for this spa??

You may need to go through the manufacturer to get the owners manual. If heat light is on then you need to verify if circuit board is supplying the heater proper voltage. If it is then heater may be bad, if not then circuit board may be the issue.
