Used single-piece Electrolux top-loading washer and dryer combo

Used single-piece Electrolux top-loading washer and dryer combo. Still functional, but black dirt sometimes appears during the wash cycle (most of it drains out or settles back into the washer holes). Likely needs a deep clean or may be good for parts. Due to a rusted screw/bolt holding down the agitator, we have had difficulty removing it for deep cleaning and have instead opted to purchase a new machine. Located in a high-rise condo in downtown (elevator access). ***Hoses and venting/exhaust coils still require disconnection when picking up*** **Pick-ups only by buyers with their own appliance dolly.** Loading zone parking available by the elevator lobby.
