Your spa’s circuit board is a printed circuit board (PCB) that you find in many 
electronic devices. The spa circuit board is designed to perform a specific set 
of tasks under comparatively extreme conditions. You can say the circuit 
board acts as your spa’s central nervous system. It controls all of its vital 
activities and automatic functions through electromagnetic relays. The circuit 
board control functions, like water-flow, high-limit sensors, operation of 
temperature, filtration, water temperature, spa lights, and jets and blowers.

When to Replace Spa’s Circuit Board?
Over time your circuit board wears out due to overheating and may fail. 
Being a spa’s the circuit board is exposed to all kinds of harsh conditions. So 
a circuit board’s life expectancy is usually between nine to ten years. If you 
take proper care and attention, then the circuit board could last as long as 
twenty years. You may need to replace the circuit board at least a few times 
over many years of ownership.
How to Replace Spa’s Circuit Board?
In the present day, most spas on the market today are manufactured using 
Balboa Water Group components. Here, the Balboa circuit boards are given 
as an example to help you know how to make the replacement. 
Here are the two most effective methods for getting the right circuit board 
for your Balboa spa. 
Method 1: Check the Serial Number:
The most accurate method for identifying and replacing your circuit board is 
the serial number. It contains your board’s product number. The product 
serial number is a series of several numbers (preceded by ‘SN’ or ‘S/N’) 
found on the rectangular white sticker on the front or back of your printed 
circuit board. The first five to seven numbers of your spa’s circuit board serial 
number represent the product number. Beneath the serial number, you find 
the model of the board. 
Method 2: Consider the Chip Number:
On a small white sticker on your board, you can find the chip number! You 
can also find the chip number written in black marker on the back of the 
circuit board. The chip number enables you to identify your circuit board 
using the handy chipset cross reference provided by the Balboa Water Group. 
It gives you the ability to track down your board’s part number and match it 
to the chipset.
