replacing the seal:
Undo the fixing (spring, twisted wire or plastic locking band) which attaches the seal to the outside shell and detach doorseal from outer machine shell. Power off, Remove the machine top, push drum towards the rear of machine and look down to where the doorseal attaches to the drum - you should seen another clamping band. Unscrew this inner drum clamping band and pull the doorseal away. Fitting the new seal is a bit like fitting a bicycle tyre on a new rim but on a bigger scale.Ensure the seal is located correctly and refit both outer and inner clamping devices. If seal is obstructed by concrete weights the front panel and the concrete weight will have to be removed before seal can be detached. If the clamps cannot be reused, go to an electrical store such as Maplin or similar and buy the longest cable clips available. Two or more clips can be connected together to form one long clip which can go round the inner part of the doorseal to hold it in place on the drum lip.
