Belling IDW604 water found on controls?

I have a Belling IDW604 dishwasher when it's finished it's wash I open the door and always find water across the controls and a fair bit on the plastic tape fitted to the underside of of the worktop. I thought it was just steam condensing as I opened the door, but my facia door on the front has started split at the top. Any ideas why it's doing this?
