LG F1480FD Can’t Find Minor leak

I’ve got an LG F1480FD, which has a minor leak, approx. 2 table spoons of water per wash.

The water comes out by the leg of nearest the pump., however there appears to be no signs of leaks from anywhere.
I have found some water in the bottom front plate (which needs to be removed to see the pump) held on by two screws.

I have found that water appears to drip into the bottom front plate from behind the main front cover (i.e. where the door is). The water comes out from where the bottom front plate clips in.

There appears to be no leaks from any part of the pump, no water on the base of the washing machine.

There are no apparent leaks from the door seals. The bottom drain of the door seal was blocked, but is not anymore, as were the 3 small drain holes between the sections of the door seal.

I’ve also cleaned out the tray as the water appeared to come from the filling tray area, as that lip on the bottom of main front cover was damp in that area.

There does not appear to be any operation which causes the leak.
No idea where to look next any ideas ???

Also how can I trigger specific actions i.e. fill, drain, flush water though the soap. Is there a service mode I can trigger?
