What is Washing machine: Definition and 36 Discussions

A washing machine (laundry machine, clothes washer, or washer) is a home appliance used to wash laundry. The term is mostly applied to machines that use water as opposed to dry cleaning (which uses alternative cleaning fluids and is performed by specialist businesses) or ultrasonic cleaners. The user adds laundry detergent, which is sold in liquid or powder form, to the wash water.

    Understanding Electric Shock in Floating-Neutral and Floating-Ground Scenarios

    Hello, let's say the AC generator and the washing machine, with a live metal frame due to a fault, are floating-neutral and floating-ground. These are many combinations where both get and get not bonded/grounded. Can anybody tell us in which case the person gets an electric shock when touches...

    Washing machine - centripetal force

    During summer i wash light items - t-shirts, boxer shorts and low-cut socks, washing machine is just 1/4 full and it cant balance during spin properly. During winter with bigger items there is no such problem. So i was wondering, could a temporary solution be to just use some kind of basket...

    Appliances Neutral drain function in washing machines

    It would be interesting to me (but not essential) to see a visual explanation of how the gear case in a Whilepool/Kenmore direct drive washer implements the neutral drain function. The neutral drain function is a period of time when the washer is pumping out water but not spinning or...

    Newton's First Law to explain Washing Machine Spin Cycle

    I truly am not sure. I assume it is that because everything has inertia, an a tendency to remain in a constant state of motion, when the clothes are quickly spun around they cannot remain in a constant state of motion (of either rest or constant velocity), but the water is "pushed"/spun out of...

    Could New Washing Machine Be Damaged by Delivery Guy?

    When our new washing machine was delivered, the delivery/installation guy ran a "test wash" cycle. I did not look inside the machine when he did this, as I stood to the side. After the test cycle finished, he left and I assumed all was good, b/c he said it worked. I could, of course, hear...

    Convert 1 phase to 3 phase by using an old washing machine

    We were in the process of going off grid when a tree fell over our power line. Hence we got off grid before we were ready as we didn't want to repair the power line. Now everything in the house runs on solar power, except for the well pump. The problem with the well pump is that it is a 3 phase...

    What lives in washing machines and eats aluminium alloy?

    The washing machine stopped spinning, so I dismantled it. Here's what I found: I'm thinking it might have become a big battery, as the steel drive shaft was embedded in the alloy drive bracket, which in turn had 6 studs bolting it to the stainless steel drum. It was all enclosed in the sealed...
