When was the last time you changed the brushes on the motor? Check the brushes by removing the motor and then the brushes. The brushes should have at least 15mm left on them. Use compressed air and blow out the motor.
This is a configuration error. There is a way to reconfigure it, if you have the technical information, but most likely you will need to replace the PC board.

How washing machine door lock works how to test interlocks
Replace door lock.
When the washing programme is started by pressing the START/PAUSE button, the bi-metal PTC (contacts 3-5) is powered by the triac on the PCB (J6-2 connector): after 2 - 4 seconds, this closes the switch (5-4) which powers the electrical components of the appliance (only if the door is closed).
The door interlock prevents aperture of the door while the appliance is in operation.
At the end of the washing programme, the PCB disconnects the interlock from the power supply, but the door remains locked for 1 to 2 minutes (PTC cooling time).
Certain models feature a pilot lamp which lights to indicate that the door is locked. This pilot lamp switches off when the door can be opened.

After turn and choose cycle by program switch, press the Start / Pause button otherwise the program will not start.
If you did everything right then the "Cd" should appear on the display, which means door lock failure.
green = The door can be opened
av = The door can not be opened at the moment
red = Door is open

Obviously, in the washing machine is residual water. Pressure switch has not switched from a "FULL" state to a "EMPTY" state and because that drain pump works continuously.
Check the hydraulic circuit of pressure switch and the correctness of the pressure switch. Also check drain pump and its hydraulic circuits.

The dispenser often has a small amount of water in it after a completed cycle so that's nothing to worry about. A lot of water usually means the dispenser needs a good clean. Pull the dispenser as far as it will go and then give a sharp tug to pull it completely out. The middle dispenser cover can then be taken out and cleaned, and so can all the other parts you've removed. The pipes in the machine and in the dispenser tray should be cleaned out well, as these usually cause the problem of retaining water. Put the cover back on the centre section securely and then push the whole tray back into the machine gently. Good luck!
