Hi. The model number is KG34E02GB/01. I can repair down to component level and can imagine that it is an electrolytic cap or similar in the PSU. My real problem is that I can't get at the PCB(s) because I can't get the top of the appliance off!
I can't understand why it is taking so long to find out how to get to the control board on this appliance! Surely, all the models in this range are of a similar construction. Does the top come off upwards, backwards, forwards? Does the plastic escutcheon/molding on the front come off? Do the doors need to come off?
Open the door and look at the underside of the facia panel.
There should be a small screw at either end.
Take them out.
Use a flat blade under the top of the facia to unclip it and while doing so, pull the bottom edge down and out.
There's no hidden screws shown in the diagram for your machine.
It should only be the 2 screws and the plastic snapping into place.
Check it out, see how it goes and get back to me.
Hope this helps
