I need a Necht service call for my integrated dishwasher?

I have just fitted a Necht integrated dishwasher and it has flooded the groundfloor. There seems to be some sort of internal leak as the appliance constantly goes through the draining process. When we switched the appliance off the water just slowly seeped out into the floor. As this was done last thing at night we did not find out until the morning. Indoor swimming pool not really appreciated. Anyone have a service number for Necht please?
