LG Dishwasher, no power at all
So got the company out to fix it under guarantee and turns out it is just a very poorly designed system for buttons. It seems to be a AC Hum touch type button. The dish washer has small sponge (5mm x 5mm) wrapped with some conductive material which is meant to be attached to metal rods which forms the button inside the machine.

This gives the 'soft touch' as there is no moving parts like a normal button.

The problem was that these little sponges had fallen off the metal post which stopped it from working the way it was intended. Simple fix to re-attach the sponge back into place.

Well the fix from the guy that was sent out lasted all of 3 days before it broke again so this time I opened it up and fixed it myself (hopefully permanently).

Dead simple job, about 15 minutes taking the front panel off and glued them back into place with some contact adhesive. 

Hope this will help someone else that has problems with a 'soft touch' button that will not work any more. Should be a similar type system for other soft touch buttons found on appliances.
