water in drip tray of ADP8332 integrated dishwasher

Hello, wonder if anyone can help please

Water is still driping into the drip tray(have had prob in past with FA/F4/F1 faults – and after removing water from drip tray and cleaning black filter at 3oclock position in sump it seemed to be cleared for while. Not been in use for some time as was getting messages a lot more frequently and been short of cash etc etc.

Anyway, took cover off today to investigate as had a few hrs off from kids, and have found tray is yucky for start(prob as result of me leaving a little water in there – though thought it was all gone at time – and it being off for couple months) I got it to run a cycle but could see a fast drip (during wash phase I think) and a slow constant drip whilst machine on “quieter” phase from same area to left of white unit at base(?base of sump??motor??)

sorry for vagueness!

Question is
is it likely a leak in motor/ sump -cant see an actual tube or anything – seems to come over top of white unit
is blockage likely to cause back up for water and thus leak in this area? If so how to start with clearing blockage.

thanks
Carmen
