Kenwood KDW12ST3A dishwasher?

I only bought this last week, used it twice, and already it's playing up! When I switch it on all the lights flash, and it won't let me choose a program, or indeed do anything! The buttons are completely unresponsive. If I leave it switched on and close the door, it shows 08 on the door indicator panel, fills with hot water and churns around for a while, then stops, without emptying the water.
Any ideas?
