Our dishwasher had E15 and the pump kept going even when we switched the on/off button to off.
We had no water in the bottom of the machine.
Thankfully we read a note from google saying you should check water inlet and filters etc. (Which we did but kinda knew it wasnt the problem). After you try all these, the trick is to tilt your dishwasher backwards whilst you still have the machine on. IT ONLY TOOK A MINUTE AND THE SETTINGS RETURNED TO NORMAL, AND HAVING COMPLETED A FULL CIRCLE IT WORKS PERFECTLY. Hope this helps you too.
