Please help me with something... on the fave of my Profilux 3, the FP symbol permanently flashes.

I have manually set it to switch to feed mose for one minute, saved it and activated it and after a minute (once the countdown has stopped), the "FP" symbol keeps flashing.

I have noticed that the pump that I want to switch off during feed pause (which is set to filter), does not activate.

How do I rectify this, or what have I done wrong?

Thanks
