About this circuit board

Common symptoms this part fixes

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

  • Spa completely unresponsive — no display, no pump, no heat
  • Pump runs continuously and won't shut off
  • Heater won't activate despite correct set temperature
  • Spa trips GFCI breaker repeatedly
  • Control panel buttons unresponsive or erratic
  • Spa stuck in error or fault code loop

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

Before you buy — quick checklist

  • Confirm your spa is a 1998 Hot Spot model — not a Hot Spring or Watkins model from the same era
  • Locate the existing board's part number (stamped or labeled on the PCB) and verify it matches 71974 before ordering
  • Inspect for upstream causes — a failed board is sometimes a symptom of a shorted component like a pump or heater element
  • Check for visible burn marks, corrosion, or cracked traces on the old board to confirm PCB failure vs. a wiring issue
  • Have your spa's wiring diagram on hand before disconnecting any harnesses

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