Have you ever wondered what it looks like inside the machine when you run a wash? It’s something that we have been wondering about for a while here at Industrial Warewashers, and so we thought we’d see what we could find.
Thankfully, a helpful YouTuber by the name of RandomRazr has the answer for us, at least for an under-counter model. With a waterproof GoPro and a light inside the machine, along with the regular load, we can see the machine in action from an all new angle.
What are we seeing here?
As soon as the door closes, the wash arms spring to life and absolutely flood the inside of the machine with water and detergent. When the door opens again, the machine stops running so that the kitchen doesn’t get flooded. Once the machine starts up again after this momentary interruption, the wash arms finish their job, and the rinse arms start up. They fill the machine with clean water and wash away the soap suds and provides a final clean on the dishes inside.
Domestic vs. Commercial
Seeing this got us wondering, what’s the difference between our commercial machines and the domestic dishwashers that you might use at home. So, we turned our search towards finding a GoPro inside a Domestic machine and found this:
Here, the phases of the wash run the same, just a lot slower. Initially when the door is closed, a reservoir of water is filled at the bottom of the machine, and then this is fully heated to temperature. A wash arm or wand is extended and starts pumping the water throughout the machine. Initially this is done with clean water as a pre-rinse, then after a timer has completed, the detergent is let loose into the machine, and mixes with the reservoir of water.
Once the wash cycle is complete, the water drains from the reservoir which is then refilled with clean, soap free water, and reheated to complete the final rinse cycle.
As you can see the pressure of the water is much lower in the domestic unit, and the baking sheet at the back of the shot still has food waste on it at the end of the cycle shown.
As you can see from these examples, the commercial machines use a lot more water, and a much shorter space of time to offer far greater cleaning results then a generic dishwasher used in the house. Commercial machines are designed to be used on repeat for hours on end every day, while the domestic machine might run only once or twice a day.
