Why do you need to run a "system test cycle"?
It will either run & heat correctly on a normal cycle or it won't...in which case you will see an error code.
when i ran a cycle it tripped the electricity.
The paperwork which came with the new element said a test cycle needed to be run before it will work properly?
You didn't say that in your OP?
If the machine trips your rcd then there is an earth fault someplace.
As far a needing to run a diagnostic cycle before the element is fit for use....that's complete rubbish.
