Samsung ecobubble false LE error?

[Aroff]

My Samsung washer dryer (wd0804w8e)  fails about 10 minutes into the wash cycle and shows an LE Error, there are no visible leaks and the pressure switch seems fine. If I select the say cycle but disable the “ecobubble” function the cycle runs fully this is true for all other cycles with out “ecobubble”. Any ideas on what the issue could be and what “ecobubble” actually is? 
 

Thanks.

LE error code is supposed to mean, "Water leak detected" but it says to reset by power cycling the machine. I can only assume power cycling is an elaborate way of saying turn off and on (at the socket). I'm not sure why the eco bubble switch would make a difference, it just creates tiny air bubbles - unless it only leaks when the air bubbles are created?
