Dishlex Global 300: Eco light flashing, pump running all night.
A site suggested it was a float switch ... indicating water in the base of the machine. Two screws at the base of the machine would yield a resivoir that could be sponged out.
I tilted the machine (as it was full of dishes) while it was on, until the red light went out. It's currently washing fine.
