Answer:

A fault has occurred in the circulation pump.

Switch the dishwasher off for at least 30 seconds

Switch the dishwasher back on.

Select the program you want.

Press the Start button

If that continues then the dishwasher may have a seized motor impeller. You can try this to unjam it as well.
