nope. all you need is good strong fingers, a lot of patience , and plenty of time if youve never done one before!
the front panel isnt removable.. you dont even need any tools!
the seal will just pull off, to refit the seal, you need to lip the inner edge of the seal on the outer plastic drum, then stretch the spring round to keep it in place, again, the front bit of the seal lips onto the cabinet, and the white band just clips together around the outside of the seal
some people like to place the seal in boiling water before they fit it, to make it a little more supople.. i dont, it doesnt work for me, makes it a little slippy for me
not a particularly difficult job – i can do it in less than 15 minutes, but then, ive fitted quite a few
good luck
