In general, THIS rust is NOT a quality issue...
Only OP know how and what products are used, so this may not apply to that particular situation. In general, THIS type of rust is NOT a quality issue...
This is in the Maytag's warranty information under what is not covered. "Discoloration, rust, or oxidation of surfaces resulting from caustic or corrosive environments, including, but not limited to, high salt concentrations, high moisture or humidity, or exposure to chemicals."
When I use bleach, I measure it out. I carefully pour it in the bleach dispenser. Then I take a couple capfuls of water and rinse the remainder down. I have a tub of wet wipes I keep near the washer, I give it a quick swipe. My 5 y/o washer is not exactly in the best climate-controlled environment, but it has no rust spots. I am not joking when I say I have put this washer through some true real-life endurance tests, but it has been used properly too (not overloaded, quality detergent, proper water temp, etc.). It looks almost like it did when I bought it though.
It stands to reason if the bleach can rust out parts of the lid and surrounding areas, it can damage other parts of the washer too especially if more than the recommended amounts were used.
At first I thought maybe the bottom of the agitator was stripped or the part the U-clip holds. Both easy to fix. Then I realized the tub doesn't seem to be turning at all. Is the belt actually moving the part? If not, maybe the belt is too loose. If belt is tight and working normally, it seems as if something like the gear case may be stripped. I'm not a repair person. It's not looking good though. I really do wonder what the shaft on that gear case looks like. The surrounding area next to the bleach dispenser and especially the splattered rust spots suggest that the bleach may have been poured straight from the bottle and not measured out. Whether or not that's the case, it is one possibility Maytag may claim as a reason to deny this repair under warranty.
There is also what looks to be a lot of powdered residue in the center of the agitator.
The washer did not look overloaded in the pix to me. The tub and agitator seemed clean.
I've included a link to a post that has some good pictures regarding repairs to the washer showing rusted out shafts on gearcase that came out of this washer or washers were the same or similar gearcase was used because this was what I was thinking as I viewed the condition of the washer. I don't have time to go back through all the posts. However, the common theme seems to be a lot of bleach, overloading, and commercial use by vets, hair salons, etc. While it's not a true commercial washer, overloading and excessive bleach are not within correct use either. This doesn't mean I think the misuse was intentional. A lot of it is because the consumer didn't have the correct information to begin with. Companies want to sell their product and more of it. What worked with older machines doesn't work with the newer ones.
Once I sorted through the biased reviews criticizing this Maytag mvwp575gw, what I did take from them is this isn't your old Maytag. BUT NOTHING TODAY IS! Treat it with care if you want it to last the 5 to 10 years life expectancy most washers have now.
