Do you mean it keeps tripping breaker or do you mean power is there but topside is blank? If you can reset breaker then check the fuses on the circuit board they most likely are blown and just replace them and you should be fine. If spa is tripping breaker you need to isolate the item that is causing the trip most likely the heater itself. You would need to disconnect the power to the heater then power up spa if breaker stays on then the heater is bad and replace, continue this process with each component Pumps, Ozone, heater etc until you find the unit that is tripping breaker then replace it.
Yes that is how Cal Spa did it, they have a C2000 topside with a 2100 board. I have had many issues with these 2100 boards I believe they are defective but that is just my opinion. I think you have a bad topside control unfortunately the only way to really tell is to have another to plug into board to check. I have seen these on e-bay pretty cheap used and you can buy one and plug it into circuit board and that should resolve the issue. Once you said that you get no response from the control panel I have to lean towards that. I would connect the safety suctions back to the board and jump the wires together if you have to as these boards are designed to have the safety suction switch enabled and without them the spa goes dead.
I'm so sorry my computer crashed the other day and I just got it back up. The easiest thing to do is to google the part number of the circuit board like 2100 and then in the google search bar type in Topside control for Balboa 2100 circuit board and it will give you all the options. I do not know for sure if this looks like yours you will need to confirm with the company you purchase it from the numbers off the printed circuit board like 2100R1A etc.
You can emove the topside control and on the underside or attached to the cord there will be a part number and then google that number to get an exact replacement.
