Thanks. It's leaking from underneath, but there is a panel right across the bottom so that doesn't help to narrow it down for you, except that it doesn't appear to be the door seal that leaks. I can't access any hoses without doing some dismantling. On my previous (cheaper) machines it has been easy to lift the lid and change hoses, brushes and suchlike, but not this one.
Following your advice I have concentrated on the front panel rather than the lid. I have removed the door, undone a 10mm bolt at the bottom of the door opening, pulled off the kick strip, taken out the 2 outer T20 screws you mention and loosened the front panel but it seems to be held by the door/drum seal. Is this the final bit that needs to come off and, if so, can you advise how to do it?
Your help so far has been great, but I think the model may be slightly different as the 8mm bolt you mentioned is 10mm on my machine and there doesn't appear to be the drain tube in the filter flap that you mentioned either. There are definitely Brownie points to be earned here from my wife if her beloved machine can be revived without a second mortgage!
