Thought i'd update this too - my dishwasher has again broken down - tried all of the below, again and its error coding within minutes of it turning on now, and making gurgling noises too - given up with it now, can't be doing with engineers to solve a, i think unsolvable problem - luckily my parents are moving house soon, and will have a spare dishwasher - so i think my ones off to the skip soon too!!!!!!
But, in the meantime, if anyone's got any remedy cures - please let me know.
