Hi Partscounterman
I have an Australian made Hoover Keymatic, not working unfortunately. (motor is missing)
I have owned/used several in the past. The water level is much higher than modern front loaders, about a third to half full. The drum is suspended on springs and cables but there is a rubber padded lip on the front frame of the machine. As the machine fills, the drum sinks on its suspension, but the front of the drum soon hits the rubber lip, the back keeps on sinking so the drum effectively tilts backwards during fill. This means the pulsator is submerged (just) when the drum is less than half full of water. Unfortunately the tilt means tumbling action is reduced, despite sounding so great, in real life the washing action is quite poor. In the tumble only programs, washing often tend to go round and round without dropping so it is very gentle but not effective. On the tumble-and-pulsate programs, the whirling pulsator created a lot of lint and tangling, still not a good wash. The drum only turns one way in all programs, due to the clutch design this can't be altered. I "doctored" my machines by disabling the pulsator (easily restorable) and lowering the water level to about that of a normal front loader by adjusting the pressure switch. (a few inches of spare water in the drum). It really improved the wash action, and with its fast spin it became quite a good performer.
