Relay 8 switching on and off for a split second

Did it do that with the test code? Can you post your code again?

Ok after lots of testing and changing code...
It only happens when i plug in the high ato topoff switch...
So im guessing its the float switch causing this...
What i cant understand is that the float switch works when i manually lift it up..it shuts off the skimmer..but it also is causing the flicker of port 8..
Once i unplug the high ato float switch then there is no flickering

Is it only the high float port that causes it?
You mentioned before that low port was doing something too. Does it mean that if high float is removed, everything work fine?
Are you positively sure that there is no water damage?
Even a single drop in the wrong place can be bad

Yes only high ato doing it..
the moment i read your comment above i opened the controller and u are right..i have found some moisture inside the controller...so this is causing all my headaches...

So should i get another board or is there a way to fix it?
