A sink plunger could also be employed to try and dislodge the blockage.

Corn Kernels, paper from tupperware, film lids and smashed glass, plus food debris, may all obstruct the dishwasher filter. Clear plastic lids could also be hard to spot if you aren’t looking for it.
Remove the filter and clean it thoroughly before putting it back in place. Not all dishwashers have their filter in the same location so you might need to refer to the manual for this.
The next component to examine is the drain hose. Stuck food, a kink in the hose or a crushed hose could all stop your machine from draining.
Depending on the location of the waste hose (usually the corrugated one) you might be able to look at it by means of taking off the base or you may be required to move the machine away from the wall.

If you can’t blow air through the hose this might be the reason your machine isn’t emptying.
Disconnect the hose at the sink end and then give it a thorough clean to remove the obstruction. If you can’t dislodge the obstruction or the waste pipe is split or damaged invest in a brand-new one. If you may get rid of the blockage then put the hose back and start a quick program to make sure you have repaired the error.
You can also check where the waste pipe attaches under your sink as well. This is a common place for a build-up of gunk so if you do remove the waste pipe give this area a good clean as well.
You could examine the drain valve by hand to make sure it hasn’t got stuck. The drain valve will usually be situated in the bottom of the machine on the valve bracket. Examine your instruction manual if you can’t see it.
Depressing the valve or giving it a wiggle should be enough to let you know if it’s seized. If you can see anything stopping it from moving get rid of this. If you can’t, this could be when you should get in touch with a plumber unless you are confident in purchasing and replacing the part yourself.
Your appliance pump uses impellers that can be blocked by pieces of glass or other objects. Check your pump isn’t blocked by taking off the cover and making sure the impellers can be easily rotated.
If it sounds unusual your dishwasher pump or motor might be damaged and need replacing.
If you have been through the above list and the error remains, or you think the pump, pump valve or motor are damaged, it could be a good time to call for help.
At least having done your best to troubleshoot you have prevented needing to pay a big call-out fee for a blocked hose.
