If the dishwasher is draining all the time then this is down to a water leak in the base which has activated the flood switch in there.
What you need to do is pull the dishwasher out and lie it on its back as this will allow the water to drain out from the base. So you will need a towel for that part.
Once the water is out the flood switch will reset itself and this will stop the pump from running all the time.
Then retry it and fingers crossed this is just a one off that caused it.
But if it does it again then theres a leak under there which you need to find and fix. For this you need to remove both side panels and then you can see the workings under there and check for any loose hoses.
Try that and see how it goes from there and let me know.
I see the question is still open here. Do you still need help on this?
If so just get back to me. If not then if you could remember to rate the answer that would be great.
