This is a pretty exciting treasure trove in a foreign country. IF the Bendix is just a washer, it looks very wide for a washer. Even though the washer is 30" and the combo is 36",the spacing of the controls looks more like the Duomatic than the washer. I'm not there so I'm probably wrong. If it is a combo, it will not be a 110 volt machine and it's strange how it lacks the Duomatic escutcheon on the front. And I don't think that the Philco Duomatic Washer Dryer is a 110 volt machine because it is looks like an electric drying condenser model. It must be the light that prevents us from seeing the door in the top panel for what Bendix owners called the "soap chute." If it were a gas drying model, the detergent door would be even larger to allow access to the dryer lint screen. It would also have a large door in the top for access to the lint screen if it were the very fast drying vented electric model or the Hi Speed condenser drying model with the blower. Otherwise, the condenser drying combos, even the Philco, were slow
Be sure to closely examine the door gaskets on the front loaders and the gasket around the top of the tub on the dishwasher to make sure that they are still pliable, not dry-rotted or torn. For those prices, especially for the dishwasher (ouch), you are paying a lot for certain headaches. You don't want to be buying the heartache of not being able to use a machine because a 50+ year old gasket needs to be found for a replacement and that drip line under the center of the door and the rust along the top of the access door on the Big Bendix sure shows that it either leaks or leaked at one time.
Check to make sure that animals have not chewed wires and hoses. Roach droppings can short out electrical components so look for that also. With the dishwasher tank locked in place, each twist of the knob at the top of the door should result in the advance of the timer dial at the bottom. The dates of domestic production (HA, something we can't say anymore about most appliances now) would be 1954 for the dishwasher and Bendix and 1960 or 61 for the Philco. Notice that the dishwasher just has a little screen cup for the detergent so that means there is no prewash, just a wash and two rinses then dry. You will need very hot water for this to clean well because the hot water for the wash is going to be cooled a lot when it hits the room temperature tank and dishes. I think you could start it and then after the water drains from the wash, you could give the upper dial two or three twists to advance the timer to off and restart it with fresh detergent in a warmed up machine for improved cleaning of heavy soil. Oh, and be sure to check the dishwasher's Bakelite impeller. If it has any chips or breaks, washing performance will be horrible and an out of balance impeller will destroy the motor bearings.
