Hot Tub PCB Installation

Do not remove and replace the circuit board unless you have tested all other components and proven that the circuit board is actually causing the problem.

The first thing is to do is to identify the symptom from the list below:

Spa PCB Associated Problems

Hot to determine your Balboa PCB type

What are the typical PCB output capabilities?

A typical circuit board has the following output capabilities:

•230 VAC System

• Two-speed pump 230 VAC, 50 Hz, 2 HP

• Single-speed pump 230 VAC, 50 Hz, 2 HP

• Blower 230 VAC, 50 Hz, 2 HP

• Heater 230 VAC, 50 Hz, 2-3 kW

• Light 12 V, 12 W, 50 Hz, I A or 120 V, 100 W

How to Remove a System Circuit Board?

• Shut OFF power to the spa at the main circuit breaker panel. Do not attempt to service a spa without shutting off the power. Serious injury or damage may result.

• Disconnect all wires and slip-on connectors as necessary to remove the board.

Note. Labelling these wires may help speed up reinstallation. We recommend taking a photo for reference, the wiring diagram should always be used to ensure proper wire placement.

• Remove all the screws which mount the board to the system enclosure.

• Remove the board from the plastic stand-offs by gently squeezing the locking flange on each stand-off with a pair of pliers. The board should now be free and can be removed from the system box

All PCB boards come in a sealed anti-static bag and once opened can not be returned other than for a warranty......Always use anti-static gloves when fitting.

• Check all jumpers and dip switch positions on the new board. Make sure they are in the same position as the old board.

• Make sure the new board snaps in place on the plastic stand-offs. Use care to be sure the connectors on the right side of the board clear the enclosure openings as the board is installed.

• Install all screws which mount the board to the system enclosure.

• Reconnect all wires and slip-on connectors. We recommend siliconing the main wires into the terminal block as they can often work loose through pump vibration eventually causing a short.

• Restore power to the spa at the main breaker.

• Test to make sure all functions work correctly.
