As a footnote if it's persistent it can lead to all sorts of probs.
b try not to leave the clocks in direct sunlight, when yer washin yer machine make sure yer cover them.
It's a complex lecy system that's in behind the clocks, it's a canbus thingy 90% of the functions run through it and it dosnae like moisture never mind water.
If yer have a good look on the AF1 site there's loads of pics etc. Tifa is yer man for the fix, whit he says works.
Might be something to do during the winter.
Good luck mucker.
