The dishwasher may actually be finishing its cycle
If the drain part of the cycle isn't hapening properly because the drain pump is not working then it may look unfinished - if you can start a new programme then the old one has finished.
It may be that the electronics are not telling the drain pump to work - or the drain pump is defective - or there's debris trapped under the pump's impeller blades - which is quite common.
You can usually get to the drain pump impeller from inside the machine - remove all the filters and search for a single Torx screw right at the bottom of the sump - remove the screw and lift off the small cover. The impeller blades may well be clogged up with jam pot labels - bits of metal foil - lemon pips etc. Tweezers may help you to remove them.
The impeller blades should move freely but with a bit of magnetic resistance.
Good luck...
