Thanks, I appear to have resolved the problem as the dishwasher is now working. Not sure what I did really. Cleaned the filters and washed through with clean water and gave the Mushroom filter thing a shake. Its been ok since.
Dishwasher wont start program as it wont stop trying to drain water out. I think its the float switch, but the manual states only engineer can do this job. Its out of guarantee so how do i get to the float switch?
