There is no pump-driven water recirculation. Flexible fins on the agitator circulate water in the tub and through the self-cleaning lint filter in the basket hub.
One of the features is that the drive motor does not drive the pump. The drain pump in these machines is a separate unit with its’ own motor.
The suspension in these machines is reported to be VERY good. In one videotaped demo I saw, they put eight pounds of phone books in the machine during the spin cycle and the thing barely vibrated. In fact, if the washer is dancing around during the spin cycle, whoever installed the machine probably forgot to remove the suspension rod, inserted to keep the tub from moving during shipping. (It’s a long rod, almost the width of the machine, that you pull out of a hole on the bottom right side of the cabinet.) The suspension system is supplemented by a liquid-filled (unserviceable) balance ring in the top of the basket.
Some customers have complained about the pump being too loud. On the higher-end models, GE put some sound deadening insulation in the cabinet, but if you don’t have one of these machines, there is an insulation kit available with panels that stick on the inside of the cabinet.
A few more tidbits of info about these machines:
1) All functions are interlocked through the lid switch except the fill cycle. The washer will not agitate, drain or spin with the lid open.
2) There is a pre-pump function built into the water level switch. The water level must be quite low before the water level switch will allow the basket to start spinning.
Most of the parts on these machines are designed to be thrown away. For example, the transmission is a tiny little thing that was designed in large part around EPA requirements (less than 3 ounces of oil, stuff like that.) It was NOT designed with rebuilding in mind.
