Product review (4 stars): Little things can fix things well
As many wrote about it, if your control panel is completely dead (no lights at all), it is probably the fuse. That was the case for me. The kit comes with the fuse, harness and ties plus the manual (1 page).

The manual states to cut the wiring as it may be the cause of the blow however mine blew after just about 6 years so I doubt it was due to the wiring.
I decided to install it without the new harness. To do so, remove the fuse by wiggling it out and push it into the old harness. I put back everything together and voila, dishwasher is working.

I believe I'll get another one to have a spare if it happens again but while I was waiting for it, I just clipped a wire and bypassed the fuse to be able to use the dishwasher, worked well, Hopefully it'll last another 6 years though...!
