Any help on fault finding a washing machine that trips the RCD?
Trips the RCD not during a drain cycle, or spin cycle. Starts a normal cycle but trips it after about 10 mins which makes me think it's related to the heating element. Could a failed element cause earth leakage? Surely if it's a big resistor that gets hot, if the outer fails and water gets in, that could trip the RCD right?
Yes. Take the back off, disconnect the heater and measure the resistance between the connection spades and the body with a cheap multimeter. It should be too high to measure, if it isn't buy a new element and swap.

Any other likely avenues to inspect?
