All about me
A genuine Jacuzzi encrypted circuit board for two pump J300 hot tubs made from June 2018 to 2024.
Fits these hot tubs
- Jacuzzi J335, J345, J355, J365, J375 and J385 made from June 2018 to 2024
Check before you order
- This is an encrypted board. It only works with encrypted control panels, and if it is fitted to an older tub it needs reprogramming with a Pick-iT kit, so ask us or your engineer before you order.
- It replaces the earlier board 6600-419.
- The one pump J315 and J325 use board 6600-498. J300 tubs from 2025 use a different board.
- The surest check is the part number on the label of your old board or panel.
- This is the UK and European (export 50Hz) version.
- Circuit boards are wired to the mains. Turn the power off at the isolator and have a qualified electrician or hot tub engineer fit it.
