While still under warranty my dishwaher quit working (the panel had no function)
The serviceman determined that the panel had become defective due, possibly to leaked moisture.
When he returned several weeks later, he replaced the panel and things were fine.

Four months and literally 3 uses later the panel is no longer functioning.
Fortunately, while waiting for the serviceman initial visit, an additional panel was mailed to me.

So, even though I am no longer I am under warranty, I have a spare panel.

The question I have is this:

What steps might I take after installing the new panel to help insure it too doesn'tthanks get moisture / or ? Damaged?
