Strange situation with socket and programmable logic

[Bagirka]

Hello,

Please help to identify my issue.

Profilux4 mega pack.

I have this programmable logic for very long time on my skimmer and it was working fine till today so not sure what is going on.

Description

I have 2 float switches:
1 in the sump - which reacts if water level rises it switched my GHL socket Nr1 off until it fixes itself)
2 in a skimmate collector (when it fills and triggers the float switch it will switch off GHL bar socket Nr1 until it's emptied, then it would automatically switch the socket "skimmer on again")

Now this morning I noticed my skimmer was off! So first I checked was my skim mate locker - to my surprise it wasn't full, then I checked the level in the sump it was ok too...so I checked my float valves and they seemed fine and not stuck.

Then I disconnected my skimmer from the GHL bar socket Nr1 and all the socket switched on again.... so I tested the float switches by hand and it was reacting as it should (push up - socket off and let down - socket on) so I decided to change the controller of my BK skimmer as I have another one...same problem...then I decided to switch into the socket Nr1 just a hair dryer ...so it behaved exactly as if there was the skimmer and switched off ...conclusion it is reacting negatively to electric item which is working on higher power as simple extension was ok....

Edit - If I turn the switch to "always on" it doesn't switch off any appliance and works fine!!!

What is going on please and how can I fix it?
here are some photos of my settings - these where working perfectly for few years!

Thank you!
