A little more info
I have a brochure for the last of these. The models described have a wood-grain finish control panel and different color lenses above the buttons. The Hi Speed Non Vent model offered for sale is not included in this group. I can't remember if ours had the wood-grain finish, but the lenses were all the same color like this one. The gray paint looks like some earlier low end Philco panels, yet it could also be a repaint job, just a little too flat for something as highly styled as this control panel. I would say it was repainted, although who would want avocado without faux wood grain? The machines were 26 3/4" wide & 27 5/8" deep. The spin speed was 560rpm. Underneath the buttons was a full width fluorescent light. No control panel is fully deluxe without a fluorescent light, but that's my 1950s conditioning.
The 4 wash buttons were labeled: Cotton, Bright Colors, Wash'n Wear, Special.
The 4 dryer buttons were labeled: Regular Dry, Wash'n Wear, Air Fluff, Dryer Off.
The timer offered a 3 or 6 minute soak cycle which would fill with either warm or cold water, tumble for the selected time, drain, give the one minute spray or flush rinse, and a short spin. The wash cycle had a 9 minute maximum wash time, the spray rinse, hi spin, and two deep rinses with a spin between them. That was probably a Bendix patent, because Westinghouse could not offer a spin between the two deep rinses until the "Dual Tumble" machine with the reverse tumbling which had a different rinse sequence. After the drain, the machine did this funny interrupted spin. The control mechanism ticked along when the machine was tumbling so when the ticking stopped, I knew that the little mechanism had gone bad in ours. What it does is give two or three brief, interrupted bursts of acceleration, followed by coasting to a tumble. This happens about three times. Then the machine shuts down for one timer increment to allow the clothes to fall from the tub wall. This step mostly prevented the clothes from sticking to the tub when the drying started. The cycle restarts with a one increment tumble and then the final spin. The original Duomatic started spinning with a slow speed spin and then shifted into the high speed spin. Philco ran into trouble with the low speed spin when they downsized the cabinet because the low speed spin allowed less than balanced loads to make the tub swing wildly enough to hit the sides of the cabinet. This was information I got from one of the owners of Annapolis Bendix who had sold Bendix machines since they were marketed. They also told me about the awful bearing problems Bendix had with the first of the Duomatics and how many of them they had to bring into the shop, take apart, pound out the old bearings and pound in the new ones.
I believe production ceased in 1968 or 1969. I remember going into a Firestone Tire store in June of 1969 and walking over to the one model on the floor and having the salesman tell me they had stopped making them. That left only Sears and GE offering combos. Sears followed up on this action by discontinuing their middle of the line combo in the early 70s.
