Problem with 18 month old diplomat dishwasher?

Hi there..

Can anyone give me some advice on my problem..

I have a diplomat integrated dishwasher, I'm not sure on the model as it was already in the property when I bought it and I can find a number on it at all.

Basically it gets used once a week, and for the last three times I have used it, it will get to half way through the cycle and then constantly beep, when I open the door a light is flashing on the first option, I have to hold the wash type and the start button together to move it to the next option, but then 10 mins later it does it again. I then take the dishes out and wash them in the sink!

I thought that there may be a blockage so I bought a dishwasher cleaner which rectified the problem for a couple of goes, now all it does is beep every time I use it..

Is the dishwasher knackered or blocked? It's integrated too so not easy to remove etc..

Can anyone shed any light on this problem?

Many thanks
