I guess this is too late for Kelvin but I'll post my answer anyway as I've just done it! This was for a Bosch Classixx Express.
Put the washing machine (gently) on its back. Locate the left hand torx screw behind the panel that hides the drain hole (bottom right) and remove it. You can then slide the bottom panel to the right and take it off revealing two screws either side of the main front panel that hold it on. Remove these. Remove the screws holding the door on and the door catch. Remove the wire holding the drum seal and release the drum seal from the front panel. Loosen a torx screw that you will find below the soap dispenser. (Remove the soap dispenser drawer to see it.)
You should now be able to slide the main panel down and remove it.
You will now see the connectors going to the heating element at the bottom of the drum. Remove all the connectors but make a sketch so you can remember how to put them back. Then just lever out the element gently by prising under the rubber seal with a wide blade. It's only the rubber seal that holds it in and it will eventually work it's way off. And there you have it - one grotty element. (Well mine was!)
Good luck!
