Problem with Beko DWD5411W ?

Hi, Wonder if anyone can help. I have a Beko DWD5411W dishwasher. Yesterday there was something of a bang from it and the power tripped. I reset the trip and found that the fuse had also blown in the plug. After replacing the fuse I find that if I power it up it the On/off light solid comes on along with the wash light and the pump starts and attempts to drain the sump. And that all it does, it just keeps pumping. If I press the Start/Stop button for 3 seconds to cancel the cycle the pump keeps running but then the on/off light flashes in opposition to the wash and dry lights which flash together and it just stays like that. Any suggestions anyone ?? All help gratefully received.
