How can i fix my zanussi DW908 multirack dishwasher?

How can i fix my zanussi DW908 multirack dishwasher? At the start of the program, it didn't alllow enough water in to cover the element, so when it heated up it smelt like it had burntout or overheated. I set it at program end to empty the water that had got in, it wouldn't empty. Ive tried a couple of websites which tells me to take this bit off, and that piece out, but i don't know what these parts look like. I have no manual to identify parts. I can't download one as it doesn't list my model number.
