Remove the filter and wash it thoroughly before replacing it. Not all filters are obvious and straightforward to remove so you might need to look at the instructions for this.
The next area to check is the drain pipe. Stuck food, a kink in the hose or a crushed hose could all impede your machine from draining.
Depending on the location of the waste hose (generally the ribbed one) you could be able to look at it by lifting away the base alternatively you could have to pull the machine away from under the counter.

If you can’t blow through the hose this may be the problem.
Take off the other end of the hose and then give it a good flush through to remove the obstruction. If you are unable to remove the blockage or the waste pipe is slit or worn purchase a new one. If you could remove the obstruction then put the hose back and start a short cycle to find out if you have repaired the error.
You may also check the point where the hose connects to the waste disposal. This is a likely spot for debris to build up so if you happen to take off the waste hose give this point a good clean as well.
You may manually inspect the drain valve to ensure it hasn’t got stuck. The drain valve will often be found in the bottom of the machine on the valve bracket. Check your manual if you’re unsure.
Depressing the valve or giving it a jiggle will likely be adequate to tell you if it’s seized. If you can see any debris stopping it from moving remove this. If you are unable to, this may be when you should ring a plumber unless you are confident in procuring and repairing the valve yourself.
Your dishwasher pump uses impellers that may get blocked by pieces of china or other objects. Check your impellers aren’t broken by removing the cover and ensuring that the impellers can rotate freely.
If the dishwasher sounds unusual your pump or motor might be damaged and need to be repaired.
If none of the above investigations has solved the fault, or you have reason to believe the pump, pump valve or motor are damaged, it may be the right time to call your local repair person.
At least having tried to fix the problem yourself you have prevented having to pay a big repair charge for a blocked hose.
