Popcorn, paper from tupperware, plastic film covers and broken glass, as well as scraps of food, may all obstruct the dishwasher filter. Clear film could also be difficult to spot if you aren’t looking for it.
Take out the filter and give it a thorough scrub before replacing it. Not all filters are obvious and simple to remove so you could need to look at the instructions for this.
The next component to examine is the drain hose. Many things could cause a blockage including a build up of food debris, a kink in the hose, or a crushed hose. All of which could all stop your dishwasher from draining.

If you are unable to blow through the hose this could be the issue.
Remove the other end of the hose and then give it a thorough clean to remove the obstruction. If you can’t shift the blockage or the hose is cracked or damaged buy a new one. If you may remove the blockage then put the hose back and run a quick program to check that you have solved the problem.
You can also inspect the point where the hose connects to the sink as well. This is a likely place for debris to build up so if you happen to take off the waste pipe give this point a thorough clean as well.
You could inspect the drain valve by hand to ensure it isn’t got stuck. The drain valve will often be situated at the base of the dishwasher on the valve bracket. Examine your manual if you can’t see it.

If you are unable to, this could be when you should call a repair person unless you are happy in purchasing and repairing the part on your own.
