Ok if it wont drain out but there is a grinding noise then it sounds like a blocked pump.
To fix this you need to scoop out all the water in there.
Then take off the plastic trim on the front at the bottom.
From there you will see the pump infront of you. This is a twist fit pump so to remove this you need to push the tab in at the top which you will see then you can twist it off.
Once off clear out any debris which is in there jamming it up.
Once its clear refit the pump and retry the machine and see how it goes from there.
No worries if you need anymore info just get back to me.
