Any number of things could block the filters including corn kernels, paper from tupperware, plastic covers and broken glass. Clear film may also be hard to see if you aren’t looking for it.
Take out the filter then give it a good wash before putting it back in place. Not all machines have their filter in the same place so you may need to look at the owners manual for this.
The next area to examine is the waste water pipe. 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 machine from emptying.
Depending on the location of the waste pipe (generally the ribbed one) you may have the means to look at it by means of taking off the base or you may have to move the dishwasher out from under the counter.

Remove the hose at the sink end and then give it a good flush through to remove the blockage. If you are unable to remove the blockage or the waste pipe is split or degraded buy a new one. If you may remove the obstruction then re-attach the hose and run a quick cycle to double check that you have repaired the issue.
You could also inspect where the waste pipe attaches to the waste disposal as well. This is a likely spot for a build-up of gunk so if you do take off the hose give this connection a good clean as well.
You could manually inspect the drain valve to check it isn’t stopped working. The drain valve will often be situated in the bottom of the dishwasher on the valve bracket. Examine your owners manual if you’re unsure.
Depressing the valve or giving it a wiggle should be adequate to let you know if it’s stuck. If you are able to see any debris stopping it from moving carefully extract this. If you are unable to, this might be a good time to get in touch with a plumber unless you are undaunted by purchasing and replacing the part yourself.
Your dishwasher pump makes use of impellers that can become blocked by pieces of glass or other objects. Check your pump isn’t obstructed by removing the safety cover and checking that the impellers can be easily rotated.
If it sounds unusual your pump or motor may be damaged and need to be repaired.
If none of the above examinations has fixed the issue, or you suspect the pump, pump valve or motor are damaged, it might be time to call for help.
