Stops at spin cycle does not drain.

Hi.
The first thing to check is the drain system. Check the drain hose at the back, and the drain pump. The drain pump can be tested advancing the cycle to drain. It can also be tested by a technician, energizing the pump directly.
The pump can be accessed removing the small service panel in front of the washer. Access to pump is located on lower right hand corner in front.
After removing the panel the pump is accessed and disconnected from hoses to remove the blockage in there. The procedure is also illustrated in service manual. Have a container ready to collect water if you DIY.
If the pump is OK other parts that can cause the problem, and that must be tested are the pressure switch, and the electronic control board.
Regards.
