Problem with Diplomat Dishwasher ADP8234?

I have a problem with my integrated dishwasher -Diplomat ADP8234.
It is not coming up with any error code.

I noticed it wasn't rinsing too well before christmas. Then one a couple of occasions, about 10 minutes into the cycle water would just start pouring out of the front under the door. When opened the dishwasher would be full of water up to the level of where the door opens.
Then i would try another programme and it would finish the wash completely with no leaks and rinsing fine.

I've tried one of the Finish wash bottles in case it was a cleaning problem and the machine went through the whole wash with no leaks.
So i filled the machine with dishes and put on a normal programme and it leaked all over the floor again.

I stopped the machine by opening the door but just left it with the water inside (it had stopped leaking out of the door). I went out a couple of hours later and when i returned it had blown the fuse and the house had been without electricity for a couple of hours.

Has it had it? I've emptied all the water out of it now. The machine is 6 .5 years old.

thanks
