Know what you’re replacing.
Standing water at the bottom of the dishwasher is usually a clogged filter, a kinked drain hose, or a blocked connection to the sink drain. Start with the filter — it's the cause most of the time.

One step at a time.
2Clean the filter
Twist the cylindrical filter counter-clockwise and lift it out. Rinse it under hot water with a soft brush.
3Clear the sump
Check the hole under the filter for glass, seeds or labels and remove them.
4Check the drain hose
Under the sink, make sure the drain hose isn't kinked or crushed and loops up high before it connects.
5Check the disposal connection
If you just installed a disposal, the knockout plug in its inlet may still be there. Also run the disposal — a clogged disposal blocks the dishwasher.
