Take out the filter and give it a good wash before putting it back in place. Not all filters are obvious and straightforward to remove so you may need to look at the owners manual for this.
The next area to check is the waste hose. Many things could cause a blockage including a build up of food debris, a kink in the hose, or a crushed hose. All of which could all prevent your machine from emptying.

If you can’t blow through the pipe this could be the issue.
Remove the other end of the hose and then give it a thorough flush through to remove the blockage. If you are unable to shift the obstruction or the waste pipe is slit or worn purchase a new one. If you could remove the obstruction then put the hose back and run a short cycle to check that you have repaired the error.
