When I sanitize my water lines (after flushing pink stuff and making pink ice), I also run the icemaker again (mine's a stand alone unit built in under the counter) and let it make ice until I smell the bleach and let everything stand overnight.
Then when flushing the system with fresh water, I run it again and let it fill the bucket. No problems so far.
