How a Washing Machine Works


Hi, I’m Matt from eSpares. In this video, I’m going to show you how
a washing machine works. Now this is a typical front loader machine made by Bosch and I’m
going to remove the whole of the front including the door, the top and the back panel, so that
I can show you what’s going on inside. So the machine works by agitating your clothes
in warm, soapy water. Let’s from the flow of water as it comes through. From the back
we’ve got a hot water and a cold water inlet. You may just be using the cold water and not
the hot, and these solenoid valves open to let the water flow through into our detergent
drawer. The detergent is washed down through this pipe and into the drum,. Now the drum
itself is really two drums: there’s this outer plastic water tight tub and inner metal
drum with the holes in it that the water can flow through. As the water sits in the bottom
of the drum, its heated up by this element, looks very much like a kettle element. And
as the water fills up, this pressure chamber here fills and squeezes air up to our water
level regulator which, when there’s enough water in the drum, tells the solenoid valves
to switch off and stop the water flow. Now, you can also see that we have this very
large weight, this counter balance weight from the front of the drum and there’s another
one here on the top. They’re just to give the whole thing a bit of stability and to
stop the machine wondering off out the door when it’s on its fastest spin cycle. Now
what’s actually causing it to spin? Let’s have a look at the back of the machine. And
here we have our motor, which is bolted to the bottom of the tub and that acts as another
counter weight. That’s turning our belt and pulley which is attached to the drum through
the water tight seal and a set of bearings. When it’s time for the machine to empty,
out drain pump here, that just pumps away our waste water up through our waste pipe.
And you can see on the front of the pump housing here, we just have a little fluff filter,
that catches any debris, stops going through the pump. And so finally, we have the brains of the
operation, which is the control module here. Now that makes all the important decisions
about when to let the water in, when to drain the water out, what temperature to heat the
water to and how fast to spin the drum at the end of the cycle. It’s also connected
to the door interlock, and that just makes sure that the door stays firmly locked whilst
the machine’s in operation. So I’m sure you’ll agree, washing machine’s
not as complicated as you first might think. And the parts inside can all be very easily
replaced. Spare parts for all makes and models of appliance are available on the eSpares
website. Thanks for watching.
