First thing to check is the drain spigot under the sink.
Remove the dishwasher drain hose from the s-bend connection,shine some light into the connection you may find it blocked up.
Clean it out,check the hose for blockages as well,put it back on and try it again.
If it still fails you need to bail out the water and look for a blockage in the drain pump.
This info is relevant for all brands.
Hope this helps !
