Just did a tub swap on this one, was a trade in for another I sold. Previous owners had just bought it used and they did not let it unfreeze from being in storage, so they called Sears to repair the pump. Once the $100 dollar pump was replaced he noticed the tub was shot! Literally! I dug into it because I have 3 other Neptunes for parts, I swapped out the whole tub and once I diconnected the pump hose a whole lot of tub plastic pieces fell out. So I guess this is the reason for the original pump failure. So I am selling it tomorrow and wandering what kind of detergent these use?
