The next place to inspect is the drain pipe. Stuck food, a kink in the hose or a crushed hose may all stop your dishwasher from emptying.
Depending on the position of the waste pipe (usually the ribbed one) you may manage inspect it by lifting away the kick plate or you may have to pull the dishwasher out from the wall.

If you can’t find any obvious kinks or obstructions you may disconnect the waste water pipe from the pump and blow into it to discover any blockages. Be sure to put down newspaper or towels before you remove the hose as even if you have emptied the dishwasher there might still be waste water in the hose.
If you are unable to blow through the pipe this could be the problem.
Remove the hose at the sink end and then give it a good flush through to clear the obstruction. If you are unable to dislodge the blockage or the waste hose is cracked or damaged acquire a new one. If you can get rid of the blockage then put the hose back and run a quick program to find out if you have fixed the error.
You may also check the point where the waste hose connects under your sink as well. This is a typical place for blockages to occur so if you do remove the hose give this connection a thorough scrub as well.
You may manually inspect the drain valve to ensure it hasn’t stopped working. The drain valve will often be located in the bottom of the dishwasher on the valve bracket. Check your instructions if you can’t see it.

If you have been through the above list and the error persists, or you think the pump, pump valve or motor are damaged, it might be the moment you need to get the professionals.
At least having done your best to troubleshoot you have avoided having to pay a hefty repair fee for a blocked drain.
