@rvitko - Yesterday, my 5017 Osmolator quit working and the "Too Low" and "Too High" lights started blinking red.
















From what I've read, the cause is most likely some saltwater got in the controller and messed up the circuit board. So I removed the circuit board and did notice what could be residual saltwater on the back of the board. So I did my best to clean it up with isopropyl alcohol, but it didn't work.

So does it look like I have to send the controller in to get fixed, or maybe get a new circuit board?

Thanks for any help :)

Usually the issue is this as shown, the power supply tip was plugged in after it landed in water, the water damage is under the power socket, if not, it followed a sensor wire into the controller, the other side is where I would check more closely. Minor water damage I can usually fix and nothing jumps out at me in either the video or the picture as being just totally ruined.

Thanks for the instantaneous response!

On the power supply tip ... The controller is on the outside of my sump and I hadn't take out the power supply tip in months, so could it still be the problem you mentioned?

FYI, after it quit working, I also cleaned the sensors in citric acid for about 15 minutes. They were really encrusted with calcium deposits, so I wouldn't be surprised if the optical sensor wasn't working. But that didn't fix it either.

So should I send it to you to fix, or is there something else I should try? If so, would I just send the controller?

Thanks again!

Also, here's some pics of the top of the board, that might help.

I believe I can see the water damage is under the power socket, it is barely visible on the right side of the socket.

Please send the controller for repair-

Tunze USA

Include a note with return address and phone number.

As follow-up, Roger repaired the circuit board and the Controller now works perfectly.

There's a reason the Tunze Osmolator is the best selling ATO out there, and that reason is Roger.

Thanks again and all the best. :)
