Jacuzzi Hot Tub Troubleshooting
Our Jacuzzi troubleshooting guides are organized by model series and year, because error codes and parts can differ between them. Choose your series below for step-by-step help from the Spa Store parts team, serving hot tub owners since 1994.
Choose Your Jacuzzi Series
J-300 Series (2014 and newer): J-315, J-325, J-335, J-345, J-355, J-365, J-375, J-385
How to Find Your Model and Year
Your model number is usually printed on the label inside the equipment compartment and on your original owner's paperwork. The year matters too: a 2014 or newer J-300 uses different electronics and parts than older J-300 models, so check both before ordering.

Safety first: Always turn off power at the breaker before opening the equipment area. Leave electrical testing to a qualified spa technician.
