Stackable washer and dryer - $90 (Tucson)

Read whole ad: Maytag heavy duty washer and dryer.
Washer is 110, I think dryer is 220 but im not sure.
I was told it was working then the belt came loose.
Maintenance person told me that he wasn't able to adjust the new belt so when motor runs the belt doesn't have enough tension to turn it.
I don't have a way to test it so I am selling it AS IS.
I don't know anyting else about it, you can not fix it here.
Final sale $90 firm
