We drained and refilled our spa. It circulates well but it stays at 80 degrees, heater is set for 101. When restarting the spa we get #20, #11 and #01 flash on the control panel before showing the temp. Does anyone have any idea what these "error" numbers are for? Any suggestions for heater? Removed filter and the heater light is lit on the panel.

Did you ever figure this out?

Thank you

Your manual should show werror codes. Otherwise, Google "California Spa error codes"
