DIPLOMAT ADP8500 DISHWASHER STAINLESS STEEL?

Hi there hoping somebody can help, my dishwasher which is only just over 12months old is flashing 2 lights. You can hear it trying to start up but it stops after a few seconds and the 2 flashing lights re appear.
I have tried where you turn it off for app 2 seconds and then press the power button again 4 times but nothing happens. Any advice greatly appreciated before it costs me a bomb to get fixed. The strange thing is it was working fine yesterday and then today nothing just them dreaded 2 flashing lights. Thanks Tracey
