Helplines are as good as useless or they wont tell you unless you pay for a service engineer.IF you happen to live near Ruislip Middlesex then call on Tom Ford he's in the book, appliance repairer, if you still can't fix it.
If my memory serves me right the water level in machines are worked by air displacement valves and if the valve is stuck like the one on my Hotpoint top loader a few yrs ago.
Undo the back plate on the machine look for a plastic bottle with thin tubes coming out and one of them will have the cut off valve in it you will have to blow hard down the end into the bottle and then if that doesn't produce an audible 'click' try the other tube. What happened with mine was the valve stuck open and the water kept flowing in. The other thing it could be is the inlet valve it's self but usually they cut out if faulty.
if it's the bottle type do a 'suck blow,suck blow' to make sure it's free and clicks on and off with ease. You could phone your library, no i'm not being funny I've done it for a washine machine door seal how to put it on and the book told me and for a Austin car I had one how to do wheel bearings. or take a walk down there and have a look.
