The last trade show I attended had the whirlpool guy there and he wouldn't even discuss the issue. Had crowds of irate plumers around him all day and never gave in.
It's an engineering design flaw that whirlpool is all to aware of. In typical fashion they will do the minimum to exaserbate the issue, re-desigh the problem and hope it all goes away in a few years. The law of odds is in their favor.
