MT Washer and Dryer
Those machines are spotless and probably came from the same home, the one loads worth of lint that is still on the dryers lint filter means that the dryer probably still works. Most people do not clean the dryers lint filter till they are ready to dry another load.
MT A712s were TOL around this time but they did not offer a 2nd rinse option, 2nd rinses were and are a great waste of water and cause a lot of additional wear and tear on the clothing and the washer and are generally not needed.
This is a long stroke clothes destroyer, the later MTs with the orbital transmission and Load Sensor Agitator are not only more effective at washing big and small loads, but are MUCH easier on the clothing. [ Maytag knew what they were doing when they redesigned the transmission and the agitator ].
