This is NOT the reason our bleach dispensers are rusting, at least those of us with Kenmore Oasis washers--specifically, model # 11.27092600 and related models.
I have NEVER spilled bleach around my dispenser, I use the amount listed, and we noticed it was starting to rust. Even the hinge on the left side of our washer is rusted through. The rust is spreading I noticed this week when I used bleach to run a load of towels.
The PROBLEM is with the bleach dispenser crappy black tube that is GLUED to this dispenser and has cracked. It is spewing bleach around your washer parts and therefore, rusting.
My husband commented what shoddy machines these were when he first noticed the rust. Even the paint is rusted through. Check out my pic. Look familiar? This is not a user problem but a manufacturer's poor quality. I have established another link HERE to find out how many of are affected as I intend to get a mass recall underway. Enough people complained about their control boards, and Sears is doing a silent recall with parts/installation paid for.
