Scum build up on drum on Bosch washing machine?

I have just cleaned the hoses and water level hose together with the drainage plubing. I found that the front pump was also blocked with scum. I was able to remove all the drainage pipes from the machine however the most difficult to clean was the white plastic unit which think controls the water level.
The scum removed will lay in the bottom of you sink suggest you do not fush away because of this. when I drained the sink a layer of heavy scum was left behind. The white plastic unit fitted inside the machine was difficult to clean I used bleach and a pressure washer out side the house. Do not get bleach on your clothes. I suggest that you have basic knowledge before starting work. I did manage to have an elecric shock due to my stupidity. Turn off the power!! Basic but I failed to unplug the unit. Still alive to tell the tail. I would sugest to buy the parts rather than tying to clean them as I have.The amount of scum removed would have almost filled a pint glass.
