Any ideas please?

Got a Diplomat integrated dishwasher (not sure which model No) and when on ECO mode it just keeps beeping twice then trying to move on in the program but then stops and beeps twice then tries to move on again. On opening door the first 4 lights are on and the 5th light is flashing. I have tried the 4 press's method with no luck. Small red reset button on bottom of machine is still in. Also tried switching off at the plug and leaving for a short while with no luck.
