why does my hotpoint fdw70 knock my rcd out?

heating element packed up, very common fault

Have same model and it tripped our RCD a few times before stopping though one wash cycle with error code A03 (thermistor short).

Web search suggested this was a component on the main board (PCB). This could be expensive to replace unless you know enough about electronics to replace the component on the board yourself (pennies for the part plus your effort)
