Use the search box on here - enter h20 - the chemical formula for water - your machine is probably not getting any.
Likely the inlet solenoid has failed but it could be a kinked hose or a blocked filter perhaps - but most likely the solenoid.
There are lots of videos on YouTube showing how to change a dishwasher inlet solenoid - much will depend on your confidence - but make sure it has water going to it before you spend money on a spare part.
Good luck...
