How do I fix my Diplomat ADP 8132?

Hi, Please help me fix my dishwasher if you can?!

I have tried a number of things but basically the door won't shut, and the lights on the different settings will not go solid (IE flashing).

We have unplugged left and tried again, we can now turn the program on (IE light will go solid) on the rinse wash, but we still cannot shut the door.

Any ideas anyone?

Many thanks
