Asko d3100. I have an asko d3100 dishwasher. Its just out of warranty and now the cup saucer light

Question

I have an asko d3100 dishwasher. Its just out of warranty and now the cup saucer light flashes and the water pump is continuing to pump even though there is no water. The dish washer wont start. What is the problem. I think the flashing cup saucer light is reporting a fault. If I know what the fault is for example faulty relay or pump then I can replace it. Can you help me with this one? Is there a service manual I prbably can get my hands on.
