Dishwasher Factory Tour: How Dishwashers are Made- Did You Know?


at this whirlpool kitchenaid factory in

findlay ohio

cutting and stamping the single sheet of

stainless steel is the first step in a


that results in this a brand new

state-of-the-art dishwasher for your new


so how does it all come together in the

beginning computer-controlled

metal-working machines bend and shape

the steel to precise specifications

this u-shaped component is one half of

what will be the dishwasher's tub

the watertight chamber where the dishes

are washed

the rest of the tub is formed using a

similar method

the components are then joined together

and in a completely automated process

the tubs are lifted and turned as they

move through the different stages of

robotic welding

when the assembled tubs come out the

other end each one is taken off the

conveyor belt and placed on a light


that will reveal any cracks in critical


at random some tubs are pulled out for

closer inspection

besides using the light table they also

put this green oil

around all of the joints wherever

there's a weld then they use a black

light to look inside to see if the oils

seep through if there might be any

cracks in any of the welds

once the tubs have been thoroughly

checked for imperfections they're put

back on the production line

and the legs braces and rollers for the

dish rack are at it

a sound absorbing blanket is built in


now it's time to put the motor in the

motors are pre-tested and a lubricant is

added to the base to help the motor fit

snugly in the seat

it's locked into place and the line

moves on

dishwashers can be very noisy and you

might be surprised at some of the little

touches the engineers have added to take

care of that

it looks like a big nut to put on the

exterior of a motor but it's actually a


absorber when the motor is turning it

has some vibration in it which normally

would make noise

but now this helps balance out the motor

and it absorbs the sound so you get rid

of a lot of that noise that you would

have with the normal dishwasher

every dishwasher has to have racks lots

of racks

the racks are assembled prepared and put

into the washers

glass holder clips are attached and the

line moves on

the dishwasher door is attached then the

control panel goes on top

now it's time for the final stages the

dishwasher's electrical system is


and hooking it up only takes a couple of


the electrical system is tested then the

dishwashers are moved onto a wash cycle

testing carousel

the washer is filled with water to test

the internal sensor mechanism

a computer checks for proper wattage and

runs a check to make sure the water is

filling the washer at the right number

of gallons per minute

there's a final check for any leaks or

other imperfections

then the water is drawn out of the

machine and it's time for the final make


the instruction manuals are put in the

water is wiped off

a little dishwashing powder is thrown in

with a touch of flare

the door is closed and the box goes on

and another finished ready to be shipped

dishwasher moves down the ramp

in the same factory using a different

process whirlpool is making tubs for

another line of dishwashers but these

tubs aren't stainless steel

they're made from molded plastic six

giant presses using high pressure and

high heat

melt little polypropylene pellets and

extrude the molten plastic to form

seamless washer tubs

then robotic arms screw metal collars

onto the tubs and in an automated


the other components are attached and

bolted on by machines

at this point a laser tests for proper

assembly at nine different places in

about three seconds after the laser test

the washer is ready for final assembly

from here on the process is about the

same as the one used for the stainless

steel washers

the motor is attached including the

noise reducer the door and electrical

components are added

the racks are put in the finishing

touches are put on they're boxed up

and rolled out for shipment to your new
