Wash cycle stops and light on the extra dirty symbol lights up

This is might be the drain filter. When the drain filter is clogged, the machine won't empty itself of water.

Candy has a troubleshooting webpage that lists many possible problems/solutions:

If you do try to check the filter, keep in mind that opening the drain filter will yield gallons of water on your floor, especially if your machine does not have the drain hose next to the filter opening. You'll need to have some way of transferring the water ready before opening the filter.

Good luck from Detroit, MI.
