How to stop a leaking door?

[Duffy]

I have had all sorts of trouble getting my Hotbin working and was having trouble with liquid leaking out of the bottom of the door; I thought this was due to the contents being too wet, which was also why it wasn't working. I almost gave up but have now got it up to temperature (between 40 and 70 degrees) so think I must have a better moisture balance but there is still liquid leaking from the bottom of the door. Is this normal? The pictures I have seen don't show anything like this other people only mention it leaking out of the grill at the bottom.
