I have a Balboa vs 500 second speed inop clicknig sound from board,but when fill tub halfway both speeds work. with jacuzzi full second speed not working and no heat. please help!

Hi,

There are some things to check.
Make sure the vents on your cabinet are not obstructed.
Make sure your filter cycle is not too long
Make sure you are not running high speed for more then 30 mins.

Have you looked through the Balboa error message site. I have attached a link follow your error through and you may find your answer. Diagnostic Messages

You have voltage across the element but no heat....

Disconnect one element connection and do a resistance/continuity test. Or use a clamp to measure running current.

Curios, why did you order another control panel? I need some history, when it worked, how it failed, any other information like if it was moved or rewired for power...etc.

Located behind the access panel there is a grey box that is the spa pack. Open that up with the 2 screws on the top of the pack. There is a small glass fuse on the circuit board. One of those fuses is most likely blown. If that is not the culprit you need a new topside control. More than likely it's the fuse.

I believe you are barking up the wrong tree.
If I understand you correctly, the pumps are backwards!!!
Pump #1 is always a 2 speed pump.
Pump #2 is usually just a 1 speed pump.
When the filtration cycle comes on, "Low" speed is supposed to be the speed that does the heating.
But when your pump is on high speed, the movement of water is creating friction and that will heat the water and provide you all of the error codes you have been experiencing.
A 2 speed pump is normally a "Circulation" pump.
as far as dip switch settings, there is a key on the label on the inside of the load box cover. It will be in a little table.

Either the spa is incorrectly wired or one of the fuses is blown in the spa pack. Typically this is due to your electrician wiring the spa incorrectly and blowing the fuse on accident.

have you cleaned your filter recently. Sound like there may be a low flow error in low speed
either that or the start capacitor on your pump is bad and the pump will not come on in low speed unless you first give it a boost in high speed
anytime you ask for heat with insufficient flow there will be an error message

If the system is the Jacuzzi 52221-05 system mentioned in the subject header, there could be a stuck relay causing the problem and you might need to get a spa technician out to assist you in repairing the problem. However...

If it is a Great Lakes system as mentioned in your message body, then there could be a programming issue allowing the filter cycle to run continuously. Provide a model number off of the Balboa control. Then we can provide you an instruction manual or reference card to assist you in resolving this problem. you can also search our online manuals at our website. You can find them online at:

Hi,

I will advice you get a technician to come to your house and take a look at it, since you are sure of the position or status of the Balboa jacuzzi, it will be better you get someone, a professional to help take a look at it, this is not (DIY) do it yourself as you can see.
