Bosch Dishwasher Keeps Filling with water at end of cycle.

Bosch Dishwasher SGV43EO3GB/22 will do the wash cycle ok. But after the beep sound at the end the water start to fill again. The water has to be turned off or the house would be flooded. I was very lucky to catch this on one night before going to bed. The water had just started to drip out the door. The next day after making sure everything was dry I put it in rinse. It was the same again everything worked ok to the end. Then after the beep it started to fill with water. This even happens with the dishwasher switched off and the door open. The only way to stop it is to turn the water off. The only other problem in 14 years was a door switch and spring. Could it be the impeller jug or solenoid valve? Maybe it’s time for a new dishwasher. I would appreciate any help thanks. [h=1][/h] [h=1][/h]
