Plug off the mains. You have to look for screws below the front kick-panel, the panel comes down & out. The pump is on the right side. Be prepared for dirty water. There is a drain hose here, disconnect & drain out. There could be a lot of water. Inside the big flexible tube (coming from the tub bottom) is the filter, be prepared to find all sorts of junk here, clean out. Examine your pump also, clean out the impeller. Carefully refit all. Your machine would be fine. Don’t wait for the machine to jam to look into your filter.
For some front loader models after removing the panel, the filter is in the compartment having the white screw able lid. The big hose from the bottom of your tub leads to this compartment.

For the door to unlock, press & hold 'end of cycle' for 3 seconds, power shd be on for this, try door after 2 minutes. Your machine may not open if there is water inside, so first drain.

That isn't the model number you give it is the part number for the logic board. The model number is on the opposite end of the motor unit and starts with 139. If you are asking if the opener should reverse when it hits an obstacle the answer is yes. If it doesn't it is not adjusted correctly or is faulty.
