How those memories flood back ...
... but not in a bad way.
Chris: I remember the silver two-dial model. Family friends had that in the early 70s. Mine was the later model with the brown fascia. Dial on the right, orange pilot light and power button on the left of the door handle. Well, door "pull", actually. There was no handle, lever, latch as such ... you just pulled with even pressure and the door popped open. Mine was stainless steel too, so perhaps the plastic interior mentioned was the earlier dual-dial model.
Mine started life as a mobile model and it tipped over just as Nathan mentioned. Once it was built in later on, it was fine. In fact we moved it to three different houses, I was so attached to it.
Regarding flooding, it never happened. In fact, I remember reading in the manual that it was flood proof. This suggests they did have problems with earlier models and therefore redesigned this one. The trick was a second water pressure switch set for a higher level. If this higher level was reached, the unit started to drain. (Single, reversible motor). How do I know? I just had to try it out, like any appliance nut would! Once filled and washing, open the door, add a jug of water, close the door ... wash ... open the door, add a jug of water ... wash ... open the door, add a jug of water ... bingo and drain!
Of course if the hose splits ...
