Im afraid the front panel dont come off on this model.
As to fitting the door seal im afraid this is the worst washer to do as its very very tight in there to do it.
What i do is with the top panel removed you will see the front dryer vent going into the top of the door seal.
Remove the screw holding that on.
Then open the door and you will see another screws there tat the top.
Then remove the metal clamp holding the vent to the door seal.
Then you can pull the front vent out from there.
Now to remove the door seal from the drum you need to peel the door seal back at the bottom of the drum and just push it down and pull and it will come off easy from there.
Now to fit the seal lean the washer backwards against a wall as this will give a bit more room.
Line the door seal up in the correct position for the dryer vent at the top.
Now you need to lip the seal onto the drum and work you way round.
Now for the spring insert a long screwdriver through the door lock and hook the spring around the screwdriver and then streach the spring around and onto the seal.
Then you need to refit the dryer front vent from there and refit the front seal.
Now this all sounds more easyer then it is. As i said these are a complete nightmare to fit and one i dont like doing due to the fact there not much room in there.
Try the above and see how you get on. If you need anymore info just get back to me.
