Wiper failure

[Michaelxc40]

Driving along today, fine weather and warning came up on dashboard, wiper failure ( see photo )
Tried wipers, nothing would work, good job it didn’t start to rain. Came home, started engine an hour later and fault cleared !!. Car us booked in with dealer in a couple of weeks for “ service repair required hand brake fault so will get them to check this out too, unless it happens again then might hit the assist button.
