Product review (1 stars): Poor Product Quality - Defective Design
We have also experienced similar problems with corrosion of the control panel and control board in our Electrolux Dishwasher.  Both panel and board have had to be replaced twice within 14 months (these parts were covered under warranty, labor was not).  It is important to be aware that the cost for parts and labor of a similar repair, when done out of warranty, could be as much as 50% of the original purchase price of this machine.
