More likely to be a pin hole in a hose near some electrical part. After all
those internal hoses do get a pounding on spin you know. I'm rather
intrigued by the memory effect of your cut out device myself. Are we totally
sure that the device itself is not suddenly ultra sensitive. Any chance of
swapping one from another circuit to prove its the appliance given the trips
when the device is unplugged.

could be leakage of the mains filter in the machine, if you test on the
plug of the washing machine, what impedance do you see across E&L, and E&N
... megger would be better than a multimeter if you have one.


Could be a chafed cable connection e.g. neutral to earth (if it was live
to earth or to neutral it would be fuses or MCBs tripping)
