    Cal spa control panel 2100 error #20, 11, and 01.
    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.

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