Samsung 9kg ecobubble - weird leak

[Megan]

Hello, we have a samsung 9kg eco bubble its about 2 years old and i noticed recently on the bottom of the right hand corner its leaking this brown fluid - its not water. 
 

anybody have any idea what could be causing this? Ive tried cleaning it, cleaning the filter, its not damaged that i can see. Picture attached

Hello Megan. Someone else had the same problem recently I think it turned out to be something that had been spilt? Basically there shouldn't be anything inside a modern washing machine leaks yellow fluid. There's nothing filled with oil either. So any leak should either be clear water, soapy water or in cases where water may be leaking into the drum bearings brown and rust coloured.

After wiping it up has it returned?
