Star washers for the heating element

thanks Andy, the heating element isn't bolted in it has two 'spring' clips that go over the ends of the element and squeeze the gasket, if you're replacing the element it's fine as they come with new ones, I just want to look between the drums. may take the bottom hose off instead, so wondered if the clips can be bought separately, thanks again for answering.

That sounds like a rubbish method they use. Have you tried looking on spare parts sites to see if they sell them? They may not sell them separately. My article gives suggestions of alternative ways of getting things out without removing the heater. If worst comes to worst and you have to you can always just fit a new heating element.
