My Dishlex Global 500 when tuned on continues to pump even though there is no water to pump out. The message on the control panel shows OF meaning what I believe is meant to be over full. This cannot be the case as the solenoids are simply not opening up to let in water. I have replaced one solenoid only, and swapped it around on both the hot and the cold but to no avail. I have check the foam floats that trigger the micro switches also.
Any ideas what I could try next?

I find that dishwashers frequently fail to empty or more likely overfill if they have been laid on their side. This causes the tube to the pressure switch to get a small amount of water in it which upsets the pressure sensor. Fix is to ensure that ALL the water is emptied out and then disconnect the tube to the pressure switch (generally at the front bottom) and blow into it to clear the water out.
