Safety first: disconnect power before you remove any panel or reach into the sump or drum. Do not touch wiring, the control board or the motor. If you see water near electrical parts, stop and call a technician. These steps are based on Bosch's published guidance [1], rewritten for clarity.

Check the hose. Make sure the hose is not kinked or damaged.
Check the pump cover. Remove the filter to reach the pump cover at the bottom of the tub and make sure it is not loose.
Check a new disposer connection. If the drain hose connects to a garbage disposer, make sure the knock-out plug in the disposer's dishwasher inlet has been removed.
