Help how do I fix this problem?

I have a indesit dishwasher DSIE2B10 I used it last night before we went to bed it's washed fine but I've noticed this morning it's still making a noise I'veooened it to find the power light flashing and the eco cycle light on I've tried to change the cycle and it doesnt let you and if I turn the power button off it turns back on itself I've checked filters and topped up salt and rinse
