My 25 year old Frigidaire FWT647 quit draining so I pulled out my mother's 1983 Maytag LA710. Pulled the front cover off; it could use some cleaning but it runs just fine.
We can help guide you to some preventative maintenance (that's severely needed at this point) if you're interested in keeping it going well into the future.
I have the 511, just like the 510 above but it has a bleach dispenser. Has run like a champ for over 40 years with one $28 part. Too bad so many Maytags of this vintage are still going strong and the newer models are already in the scrap heap.
