How can I fix my Asko 1805 dishwasher?

The control panel is no longer operational. The leds do not turn on, though when I turn the on/off switch, there is power and the fan still runs, so I know it is still getting power. I need help in understanding how to get to the panel ( take apart the front door) and then what to check for on the control panel. I have electrical test equipment ( DMM, oscilloscope) and have some electronic circuit knowledge but I can't find a schematic for the panel, so I am wondering if anyone else has had any experience with this type of repair. Many thanks!

Asko Asko 1805 Kitchen Appliances, Dishwashers Dishwasher Control Panel

Well, I've tested the circuit board. I found DC voltage which runs the relays ( ~24v) ( and one of the relay turns on when first powered on) so I knew this was good. I also found the DC voltage which ran the cpu ( (~5.4v).

The leds on the panel all appear to be run by the CPU, so if they are not on, my only conclusion is that the CPU has gone kaput. I noticed that there is very little circuit protection and the circuit board is extremely rudimentary ( single sided board with all discrete through lead compoments ). This is a disappointment really because the rest of the dishwasher appears to have good quality parts.

So, as a result, this thing is a piece of junk. The board can be replaced but it's about $400 US, which here in New Zealand would mean about $600 NZD, nearly the price of a new dishwasher.

So thanks, corporate world, you've just wasted a huge amount of resources because you've produced something which is not reparable!

Btw, I've bought a used dishwasher to replace this one for $120.
