how can i fix my dilomat adp8332 dishwasher?

Diplomat ADP 8332 dishwashergives fault bleep within 1 or 2 minutes of starting programme, though no fault code comes up within time and failure display. Immediately the bleep alert starts the machine sounds as though it is starting to drain and then stops. When door is opened the programme has jumped to pre rinse and the start light is flashing 9 times Have you any advice please?
