My caldera spa is not working. I have replaced the main

Customer Question

Hello. My caldera spa is not working. I have replaced the main circuit board, heater board, heater, circ pump, top control panel, thermostat between circ pump and heater and high limit switch. There is a big green light on inside panel and two red lights. Control unplugged andD17. The top control panel has four dashes.
My local dealer has given me the run around. Do you have any idea what it could be?

hello,

this is a watchdog alarm...does the unit try to run after a reset or goes straight to 4 dashes?

Customer: replied 1 year ago.
It clicks. And the circ pump starts then the dashes and lights on circuit board
