If you believe this may be the situation, or you just want to be sure it’s not the issue run your machine again on a quick cycle.
A few dishwashers may have an empty cycle meaning it’s worth checking your owners manual or doing a quick internet search to find out.
If you have a disposal inspect this first as a blocked disposal will block your dishwasher from draining. Turn on the waste disposal with plenty of water to ensure there are no obstructions.

A sink plunger could also be utilized to attempt to shift the obstruction.
This may be all you need to do to let your appliance to empty so run a short rinse and empty program now. If not you may remove the dirty water by hand using a bowl and a sponge and have a look at a few more likely causes.

Any number of things could block the filters including corn kernels, paper from containers, film lids and smashed glass. Clear film can also be difficult to spot if you aren’t looking for it.
Take out the filter and wash it thoroughly before replacing it. Not all filters are obvious and simple to remove so you might need to look at the instructions for this.
The next place to check is the drain pipe. Stuck food, a kink in the hose or a crushed hose may all stop your machine from draining.
Depending on the position of the waste hose (normally the corrugated one) you may be able to view it by means of lifting away the kick board alternatively you may be required to move the dishwasher out from under the counter.
Visually inspect the hose first to find out if it has been squashed or kinked. You may have the means to fix these issues by hand which is likely to fix the issue, however, be aware that when this has happened it is significantly more inclined to happen again so you might need to order a new hose.
If you can’t find anything you can take off the waste hose from the machine and blow into it to discover any blockages. Make sure you line the floor with newspaper or towels before you remove the hose as there might still be dirty water in the pipe.
If you are unable to blow air through the hose this might be the problem.
Disconnect the other end of the hose and give it a good flush through to clear the blockage. If you can’t remove the obstruction or the waste pipe is split or worn acquire a new one. If you could get rid of the obstruction then re-attach the hose and start a quick program to check that you have repaired the issue.
You could also examine the point where the hose attaches under your sink as well. This is a typical point for debris to build up so if you happen to take off the hose give this point a good clean as well.
You can inspect the drain valve by hand to check it isn’t seized. The drain valve will generally be found in the bottom of the dishwasher on the valve bracket. Check your manual if you can’t see it.
Depressing the valve or wiggling it a bit will likely be enough to let you know if it’s seized. If you are able to see an object stopping it from moving carefully extract this. If you are unable to, this may be a good time to get in touch with a repair person unless you are undaunted by ordering and replacing the part on your own.
Your water pump uses impellers that could get blocked by broken glass or other objects. Check your impellers aren’t broken by taking off the safety cover and checking that the impellers can be easily rotated.
If the dishwasher is making funny noises your dishwasher pump or motor might be damaged and need to be repaired.
If you have been through the above list and the problem persists, or you suspect the pump, pump valve or motor are broken, it may be the moment you need to call for help.
This way though you will at least be able to give them more information and have prevented needing to pay a hefty repair fee for a blocked hose.
