Hello
I also have a similar problem, the dishwasher is stuck on pumping out, tipped in water to see if it would pump it out and it does, (about 5 litres) leaves a tiny amount in the bottom (less then 3mm deep) which I think is just due to flow,
So I had a look flood switch seems ok, not fired clicks in and out and no sign really of water and tray was a bit damp but nothing major and the inside of the machine seems dry,
Out of desperation I have checked the pump but that is fine no blockages,
Any ideas? I have tipped it forward and backward, water comes out and it seems to fill briefly and then stop and pumps out, does this seem like a leak, how mu/h does it take to trip the switch as I would of thought a fairly substanstional leak and that I would at least find some water residue but their seems to be very little? (obviously its hard to tell that it doesn't pour away but the inside seems dry.
It is as if the flood switch is always on or its stuck on pumping away.
If you have expertise or know of anything I have missed please let me know I hate not being able to fix stuff drives me insane
thanks
