I didn't buy another control board, I fixed my faulty one: kzfaq.info/get/bejne/kNNzjLulnMfOoJc.html

If I remember correctly my thought was to initially leave them attached to washer and drop the lines in a bucket to drain. Since they connect directly into the wall shut off not much of any residual water would be coming from that end. I knew the lines would have water in them but I wasn't sure how much water the actual washer would still have. Leaving them hooked up to the washer and dropping them in a bucket ensured most water from the lines and washer drained making less of a mess.
