Common symptoms this part fixes

If your spa is showing any of these signs, this part is likely your fix:

  • Spa displays error codes and will not respond to panel inputs

  • Spa functions unresponsive after power reset

Before you buy — quick checklist

  • Confirm your existing control panel part number is 6600-385 before ordering — do not rely on model name alone
  • Verify your spa is a 780 Series with a 2-pump (dual pump) configuration, not a single-pump 780 variant
  • Check whether the fault is in the topside panel or the control pack itself before replacing — these are separate components
  • Inspect wiring harnesses and connections for corrosion or damage that may have caused the original failure
  • Confirm your spa's voltage supply matches the electrical requirements of this control pack

Reading the checklist now prevents 90% of returns. Worth the 60 seconds.
