If your washing machine does not turn on lights or make noises, it probably has come to an end. You have correctly performed the necessary tests. Now I recommend that you request the services of a specialist. You will save time and money. Believe me.
I noticed the washed dose this if I run a bath sounds daft but it's like it's not getting enough water feed whilst I'm using water else where and once my bath turns off error message goes away
You may think u have checked all but underneath there is a black soft rubber hose and sometimes a sock can get sucked into this and stops draining worth a try if not maybe your pump is gone
Remove the hose to the sensor switch at the tub end and check for obstruction. The small container on the side of the tub may be clogged. Clean with a small drill or piece of wire.
Without testing I would suggest that the heating element has shorted to earth enough to take out the RCD.
You should test with a multimeter between the element and the outer sheath which should show 0 if Faulty and replace the element, otherwise it is something else in the circuit i.e. temperature cutout causing the earth leakage.
A very simple solution to r epairing all by yourself is getting help from handbo oks, they're very detailed and complete in every way so for me it was my best source to repair

Either lay the machine on its back , you can see the motor underneath, the brushes are on the back end of the motor , or with the machine upright, remove the back plate , the motor is bolted onto the machine at the bottom
Make sure water is cut on at faucets. Make sure screens in hoses and valve aren’t clogged with debris. Make sure hot and cold water hoses aren’t reversed.
