Jandy one touch control panel indoor locked up on Firmware rev B12

[poolHA]

I tried power on n off power center outdoor by pool pump but same message dispalyed.

Voltage between green n red terminals shows 9.7 on DC mode multimeter at outdoor power control and one touch connections so does this mean the wire is fine and bad circuit board?

Is there another way beside replacing the control panel for >$1200? It worked fine before. The only event I recalled was pool service guy flooded the pool equipment area which striped pool pump circuit breaker. Then he quoted me 3K to replace the pump. The pump worked fine after the water dried up. Not sure if that has anything to do with locked up one touch control panel.

I appreciate any advice

Welcome to TFP.

Did this just pop up out of the blue?

Had you made any changes to the Aqualink?

You check the cable from the OneTouch to the Aqualink that no rodents chewed it and it makes a good connection in the panel. You may want to try replacing the cable.

Did you try calling Jandy Support and see if they will talk with you?

This indicates a loss of serial data communication between the Aqualink PCB and the OneTouch controller. Pull the controller off the wall and inspect the red 4-pin terminal block on the back. Make sure all four wires, particularly the two in the middle (data), are secure. Pull the front panel off your Aqualink box and do the same thing.

If the connections are secure, bring your OneTouch controller outside and make your own 4 wire harness to go from the red plug on the Aqualink to the controller (CAT5e cable works great if you have a scrap piece). If it STILL doesn't work after that, the problem is either the controller or the Aqualink PCB. You can find used OneTouch controllers relatively inexpensive on eBay. You can also swap it out with an All Button controller if you prefer that or find one cheaper.

If the pool guy got the inside of the Aqualink box wet, it certainly could have caused some short on the PCB or maybe corrossion on the terminal block.

No changes made to Aqualink recently. I used multimeter to check voltage at both ends of wire. Voltage between green n red terminals shows 9.7 on DC mode at outdoor power control and one touch connections so does this mean the wire is fine and bad circuit board?

Checking voltage is not a good test for a digital connection.

Do this…

bring your OneTouch controller outside and make your own 4 wire harness to go from the red plug. on the Aqualink to the controller (CAT5e cable works great if you have a scrap piece)

I bought $1 worth of 22AWG cable by foot from Lowes and connected One touch directly to Aqualink power center. One touch returns to normal. So nothing is wrong with One Touch when attached directly to red plug on the front of Aqualink power center.

Pool Builder connected Jandy AquaLink RS Multiplex Board 6584 to front red plug. One Touch red plug is attached to multiplex board with another plug which I have no idea ( Heater? since I don't have salt water) . So look like I have bad multiplex Printed Circuit Board

Nice job troubleshooting that! Generally, you can successfully put two devices on one 4-pin connector. If all you have is the heater (or whatever it is) and the OneTouch, you could probably skip the multiplexer board all together. Just connect the OneTouch harness and the mystery device harness in one terminal block together on the Aqualink PCB header.
