Advise your Sister to send the machine back...
I would be surprised that Lowe's would attempt rewiring the preset rinse level, and that sounds like the only remedy...
A friend here in Atlanta purchased the same machine a few months ago...
Upon discovering the rinse cycle, Lowe's delivered a replacement machine (not sure of the brand) the next week with no problem...
And Tom, that's exactly what we did on subsequent loads...
Stopped the machine after the first spin, reset to "wash", and achieved as close to a real "rinse" as possible, stopping again after the first spin...
Subjecting your clothes to the rinse cycle is tantamount to death...
Wonder how many owners of this machine, as well as the comparable Admiral, Estate, and Inglis models, don't realize how the rinse works...
And I think the entry level price makes this one of Lowe's best sellers...
