Common symptoms this part fixes

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

  • Spa displays persistent HH or OH fault code that won't clear
  • Spa will not heat or hold temperature
  • Filtration cycles not running on schedule
  • Spa unresponsive to topside control panel inputs
  • Heater cycling on and off erratically
  • Spa powers on but jets and functions fail to respond correctly

Not sure if this is your problem? Try our diagnostic centre or .

Before you buy — quick checklist

  • Confirm your spa's existing control board part number matches 76840 — check the label on the board itself before ordering
  • Verify your spa model is compatible with the IQ2020 Hawk system — not all Hot Spring or Hot Spot models use this board revision
  • Rule out a failed topside controller or sensor before replacing the main board — these components are often misdiagnosed as board failures
  • Check that your incoming power supply and GFCI breaker are functioning correctly before swapping the board
  • Document all wiring connections with photos before disconnecting anything from the old board

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