Zanussi ZDV12001fa dishwasher starts, fills, empties then st

Hi everyone any help would be appreciated.

My dishwasher as in the title has a problem

So..
– I turn it on and select a cycle
– shut the door
– water starts to fill
– it then empties
– garbled for a few seconds
– then stops
– beeps continuously

I have tried a few things and in doing so I’ve noticed the bottom sump float with water around it. I know this causes it to stop or whatever. I noticed water dripping from a grey small hose that comes from the front of the dishwasher somewhere.
There’s no end on this pipe just clipped onto a bracket alongside a black same size pipe.
Im guessing this could be an overflow pipe or something but obviously his puts water around My float.
I don’t know what is causing this I’ve been trying for a couple of hours with no clue about dishwashers haha

Many thanks

Shaun 🙂
