Any number of things could block the filters including corn kernels, paper from tupperware, plastic covers and smashed glass. Clear plastic lids may also be difficult to see if you don’t look carefully.
Take out the filter and clean it thoroughly before replacing it. Not all machines have their filter in the same place so you may need to refer to the instruction manual for this.
The next area to inspect 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 can all prevent your dishwasher from draining.

Remove the hose at the sink end and give it a thorough clean to get rid of the blockage. If you can’t shift the obstruction or the hose is split or degraded acquire a new one. If you can remove the blockage then put the hose back and start a quick cycle to check that you have fixed the error.
You may also check the point where the waste hose connects under your sink as well. This is a common spot for debris to build up so if you do take off the pipe give this area a good clean as well.
You could check the drain valve by hand to check it hasn’t got stuck. The drain valve will most often be found at the base of the machine on the valve bracket. Examine your owners manual if you can’t see it.
