how to fix it?

I have a built in Matsui MF160. When a cycle is running steam escapes in a jet from the top and has now damaged the wooden work surface.

I see we have no condensation strip in place and there is a gap between top of dishwasher and work surface. I can see the felt top of the dishwasher.
Installed by man who built the house
Help please- have ordered condensation strip but don't think this will stop steam escaping
