If you’re lucky the standing water you have discovered may not be a fault at all. Instead, the cycle may have been cut short.
The cycle may have been interrupted for any number of of reasons. Children pressing controls, inadvertently leaning on the controls, a power outage or opening the machine mid-cycle could all prevent the program from completing and mean your machine doesn’t drain.
If you think this may be the situation, or you think it might be worthwhile checking start the machine again on a quick program.
A few machines might have a drain capacity so it’s worth checking your manual or consulting google to find out.
If you have a waste disposal check this first as a blocked disposal will stop the dishwasher from draining. Run the waste disposal with plenty of water to make sure there are no blockages.

If you sink is emptying inefficiently this might indicate an issue with the drains rather than an issue with your machine.
In the case that the sink is draining slowly you could attempt putting a little bicarbonate of soda and vinegar down the drain, letting it sit for a while and subsequently flushing it through with hot water.

This may be enough to permit the appliance to drain so start a short rinse and drain program at this point. If this hasn’t worked you may manually remove the dirty water using a jug and a towel and have a look at the next few possible issues.

Remove the filter and give it a good wash before putting it back in place. Not all filters are obvious and easy to remove so you might need to refer to the manual for this.
The next place to check is the waste hose. Stuck food, a kink in the hose or a crushed hose may all impede your machine from emptying.

Disconnect the other end of the hose and then give it a good clean to get rid of the blockage. If you can’t shift the blockage or the pipe is slit or damaged purchase a brand-new one. If you may clear the obstruction then replace the hose and run a short program to find out if you have repaired the fault.
You may also examine the point where the waste pipe connects to the waste disposal. This is a typical spot for a build-up of gunk so if you happen to take off the pipe give this connection a good clean as well.
You could examine the drain valve by hand to check it isn’t stopped working. The drain valve will usually be found in the bottom of the machine on the valve bracket. Examine your instructions if you’re not sure.
