Thank you for the manual, JWWebster.
After a little more investigation, I found out how to release the plastic front cover without breaking it.
I have uploaded photos which might give others a clue of the solution.
The first photo shows the upper panel from the front side. The red arrow shows entry point were you need to use a mid-sized, flat screwdriver. As you can see on photo 2, right under the top, near the blue arrow, is a plastic tab you have to push down. First you will have to lift the plastic as I indicates with my thumb, then push the screwdriver in and release the front panel. Very difficult to spot. Use a torch and try to locate it before you try the screwdriver
And as others have stated, if there is trouble with earth on such things as a dryer, it's ether the motor or the heating element. Very easy to debug.
On picture 3, I have taken off the top plate. On the rear of the machine, near the top, there is a (in my case) red switching mechanism.
1. No electricity connected.
2. Remove top cover
3. Remove the two connectors as indicated with red arrows.
4. Connect power cord
5. Run the machine
If the fuse does not disconnect because of earth problem (goes blue as on my fuse), it's the heating element.
