In the case that the sink is draining inefficiently you can attempt putting some bicarbonate of soda and vinegar down the drain, leaving it for a while and then washing it away with boiling water.
A plunger might also be used to attempt to remove the blockage.
This could be all you need to do to permit the appliance to drain so run a quick rinse and empty cycle to check. If not you can manually remove the standing water using a bowl as well as a towel and have a look at a few more possible issues.

Any number of things could block the filters including corn kernels, labels from tupperware, plastic covers and smashed glass. Clear glass may also be difficult to spot if you aren’t looking for it.
Take out the filter then wash it thoroughly before putting it back in place. Not all machines have their filter in the same location so you might need to consult the owners manual for this.

If you are unable to blow air through the waste pipe this might be the issue.
Remove the hose at the sink end and give it a thorough flush through to get rid of the obstruction. If you can’t dislodge the blockage or the waste pipe is split or worn acquire a brand-new one. If you could clear the blockage then put the hose back and start a short cycle to double check that you have repaired the error.
You can also check where the hose attaches to the waste disposal as well. This is a common spot for debris to build up so if you happen to remove the waste pipe give this connection a thorough clean as well.
You may examine the drain valve by hand to make sure it hasn’t stopped working. The drain valve will often be located in the bottom of the machine on the valve bracket. Consult your instructions if you’re not sure.
Depressing the valve or wiggling it a bit will likely be enough to find out if it’s seized. If you are able to see anything blocking it remove this. If you are unable to, this might be the right time to get in touch with a repair person unless you are happy in ordering and replacing the component yourself.
