Before you buy — quick checklist

  • Confirm your J-300 series spa was manufactured June 2018 or later — earlier J-300 models use a different keypad
  • Locate the existing part number on the back of your current keypad and verify it matches 6600-383
  • Check whether your spa has a 2-pump configuration, as this keypad is designed for that setup
  • Do not order based on visual similarity alone — Jacuzzi produced multiple keypad form factors for the J-300 line

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