Sorry I also forgot to say that the the problem I was having (Flashing Fast and Delicate lights, Dishwasher draining and not finishing its cycle) was a intermittent problem.
It did seem that the water was heating up each time but would not finish the wash / rinse cycle.
It did start off that 1 in 10 washes would have the problem, but then started getting worse to the point where 3 in 4 washes would have the problem!
Thanks
