In newer models, there is a drainage motor instead of a magnet. In principle, it is removed in the same way as the magnet. Use these instructions

Remove the two Torx T15 screws on the drain motor and take out the motor. The side with the blue cable is marked with a dot.

If you have only removed the motor to make further repairs, you can proceed to the next step.

First leave the motor connected. Trigger a flush and observe if the pin moves back and forth.

The motor does not necessarily need to be replaced. Bend away the four metal tabs on the motor flange and detach the metal housing from the black gear case. Now you can try to turn the armature. The pin should move smoothly back and forth. If not, some silicone grease on the drive worm can help.
