About this circuit board

The Jacuzzi J380/J385 Circuit Board 6600-101 is the main control board for Jacuzzi J380 and J385 series spas. This LCD-equipped board manages your spa's complete electrical system, controlling three pumps while coordinating heating, filtration, and user interface functions. The included ribbon cable ensures proper connection to your spa's display panel.

This genuine Jacuzzi circuit board replaces failing control systems that cause error codes like HH (high heat) or OH (overheat), restoring your spa to full operation. We guarantee exact fitment for your J380/J385 model and back every board with our 1-year warranty. Most orders ship same day for fast repairs. This is a direct OEM replacement requiring basic electrical knowledge – verify your model number and disconnect power before installation to ensure safe, proper replacement of your existing control board.

Common symptoms this part fixes

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

  • Pumps not responding to control panel inputs

Before you buy — quick checklist

  • Confirm your spa model is J380 or J385 — check the equipment bay label or owner's manual
  • Verify the existing board SKU matches 6600-101 before ordering
  • Rule out a failed temperature sensor or high-limit switch before replacing the board — these can trigger the same HH/OH error codes
  • Disconnect all power at the breaker before removing the old board
  • Inspect the ribbon cable and display panel connector for damage — a bad connection can mimic board failure
  • Document all wiring connections with photos before disconnecting anything

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