Customer Question

I have a Balboa VS 501 controller on my spa. I cannot get the pump to turn on. When I press the jets button I can hear a click, I am assuming is the relay, but the pump does not turn on.
As a result I get a prime error. I have tried turning the power to the spa off for a period of time and turning it back on.... whatever I have tried I am not able to get the pump to turn on.

Hello. My name is ***** ***** allow me a moment to review your question thoroughly. I'll do my best to answer your question and resolve your issue.
On your control system there will be a dedicated fuse on the circuit board for each pump. If your system is a 1 pump model, you will have a 30amp fuse in the upper left area of the circuit board. If this fuse is bad, the relay will click and the pump will not be powered. Check/replace this fuse with an exact replacement. Home Depot/Lowes, ect will carry these.
If you sometimes hear the pump hum for a brief period followed by a click sound, you may have a seized up or bad motor. The pumps have a built in thermal overloads that will disable the motor in failed starts.
If the motor is always silent, check that fuse and replace if necessary or in doubt.

Thank you, ***** ***** got the pump working. I am also having trouble with the GCFI breaker. As soon as I turn the breaker on it trips. If I bypass the GCFI the spa works just fine, but for some reason the GCFI trips automatically. Is there some kind of setting I can adjust, I saw on another question something about changing the dip switches.Thanks.

Okay, at least we have 1 issue down. Those fuses blow sometimes and once replaced everything is usually fine if the new one doesn't blow immediately.
Since that is resolved, please take a moment to rate my help so far and I will be glad to help you with the gfci tripping...we can just continue on this thread without paying for a new question.
You may still have a pump issue, however, more likely you have a bad heater. It is the single most common reason for gfci tripping. So, lets try this:
I would like you power off the breaker completely and carefully remove both copper heater tabs from the heater. You will see 2 copper strips that go from the circuit board to the heater terminals, just use a 3/8" wrench or some small pliers and remove those 2 nuts. Be careful not to twist the terminals when loosening the nuts. If you start to twist the terminals, use a 1/4" wrench or needlenose pliers to hold the terminal below the copper strip while removing the 2 small heater nuts.
Then carefully bend the 2 tabs up and off the terminals so they are not touching anything. Now, repower the tub and update me what happens.
