Turn off the water

Close the dishwasher supply valve if any active leak is visible.

2

Let it drain

Keep the door closed while the automatic drain operates unless water is escaping.

3

Check visible connections

Inspect the sink-side drain, supply valve, and floor.

4

Check detergent

Use only automatic dishwasher detergent; hand dish soap can force suds out.
