Jacuzzi J-375 control panel blank
Jacuzzi Jim:
Bad topside. If it's the LCD one it's part number 2600-323 2002 to 2006. 2007 to present is 2600-328 Like mentioned get one from the dealer or find it on line.

I also have another control panel on the other side of the tub too. This one is also blank and won't show any numbers, letters, etc. Are the two panels controlled by one another? For example, could it be a bad fuse or something since BOTH panels are not showing any information on them?

The one at the back of the spa doesn't light up, it should just be a sticker. If it does light up, I would love to see a picture of it. And yes if I remember right it is connected to the main topside. There are no fuses. You might try unplugging the main topside from the circuit board and reconnect it. Doubt it will work but worth a try. 99.99% sure you need a new topside.
Buck Mark:
Thanks Jacuzzi Jim. If it is in fact a bad topside, would that cause my jets to kick on and then turn off after a few seconds? Is that some kind of safety feature so the motor doesn't burn out or could this be a separate issue altogether? Or, could the jet issue be an airlock since I just drained and filled it a few days ago?
Also, I may have gotten some water behind the topside as I was cleaning it. Is it worth trying to disconnect the topside wire and clean and dry it out before plugging it back in or is this thing fried? Any other thoughts/suggestions to try. I am going to take off the panels and look at it tonight. I really appreciate the help!
Jacuzzi Jim:
The jets might be kicking in as a freeze protection, probably not related and if the jets are flowing water there is no airlock.
As far the topside it is possible water got in there and you can try drying it but very doubtful water made it that far in to the connection at the board. I have seen moisture (condensation) behind the display before, in fact I have it on my own spa with a dead bug under the screen as well, but mine works fine. Most times the LED display will look like Russian letters or only partially visible display before it dies. Your stuck buying a new topside buddy. :'(
If you are doing it yourself you need a large screwdriver to pry it up by working your way around it slowly. Once off you will see a well under it with a hole that the cable goes through. There might be water built up in there, if so I have drilled a small hole in the lowest part where water traps to let future moisture drip out. When/if you get the new one, clean the whole area really good with rubbing alcohol and let dry. Drop the connection down the hole. Then when you are ready to stick the topside to the acrylic you have one shot to get it right/straight. The sticky tape that holds it on is a one shot deal and once it's on it's on. Good luck to you!
