- Ask This Old House plumbing and heating expert Richard Trethewey takes host Kevin O’Connor inside a dishwasher to explain each cycle.

Steps:
1. A dishwasher begins the cycle by running a discharge pump to empty any remaining liquid in the machine.
2. Next, hot water enters from the side and fills a reservoir at the bottom until it activates a float. In some cycles, an electrical element can heat the water to sanitize dishes.
3. Once the reservoir is filled, a pump sprays water and soap all over the dishes.
4. At the end of the cycle, the pump will discharge water out of the drain.
5. The number of cycles is determined by user settings.

2:57 im impressed by the power of that tower
One thing not mentioned anywhere in video or comments is that many dishwashers have a turbidity sensor. This senses how dirty the drain water is and based on that runs more cycles. I found this out when replacing my bottom rubber tub on my GE washer
Also, even if you use a pod for the main wash. Use a little liquid for the prewash. That little bit of extra cleaning time can go a long way, especially for a load of pots and pans.
It is also worth checking the owners manual. Many dishwashers do not heat the prewash water, because it is a shorter part of the cycle. In that case, run your kitchen faucet until you get hot water, right before starting the dishwasher. Hot water simply cleans better.
Thank You for showing us the inside of dishwasher and how it works!
i open the door of mine just after second rinse and let my dishes air dry inside the machine, I save energy and reduce the amount of hard water marks created by fast dry from heat element.
Thanks Richard! I knew how it worked but that was very interesting to see the actual operation from inside.
Kitchenaid actually makes a dishwasher with a window in it in case you are bored enough to want to sit in front of it and watch it wash the dishes LOL. Its not a cheap dishwasher though they're $1k+ for those.
Tip: If you have a manual knob dishwasher like this one, make the selection on the rotating knob before closing the door completely. Otherwise, the internal contacts of the knob will electrically arc as you spin it, prematurely wearing them out.
Learn from my mistake, and save yourself a couple hundred bucks on that repair.
THANK YOU!
Thanks!
Thanks! I've always wandered what was going on in there.
Great segment, thanks!
My caloric built in 2000 is similar but has a smaller arm above top rack, schematic shows it has water pumped to it, been cleaning out lime or scale today of both arms, manually and running vinegar through it after, was all clogged up, still don't think it's spinning yet or it's for a certain setting, the bottom arm is ok IDK, just bought the place. The bottom arm has small metal heat shields where it stops above the heat element, make sure they stay on!!! Pretty sure I'll have it working ok.
This is like ASMR to me.
Richard is the man!
1980's called & want their dishwasher back
That's less than 10 years old. It's just a basic model. I'd take that over the ones with all the buttons that barely last a decade.
"This Old Dishwasher".
Brilliant invention
One of the best videos ever! Thank you
how did they get the camera man in there?

Awesome video thanks!
Perfect video. Thanks bud
my dishwasher often goes to 99+ hours setting when I have chosen a time saving setting (like 50mins). I have noticed that happens usually when I have not ran the dish washer for 3 weeks or so, but I don't have that many dishes per day to run the washer sooner than once every 3 weeks. please help
Since my hot water initially comes out cold for a few minutes, does it help to run the hot water into the sink until it’s hot, before starting the dishwasher?
I love you guys videos. very helpful
Cool
I have a dishwasher that doesn't drain what should I do I cleaned all the screens?
I have the same washing machine but it leaks like the time Richard put the wrong soap in one😂
The water hook up in europe is cold water . The machine does all of the heating of the water.
In India too
Do you believe it is necessary to affix a shield (say aluminum skin) to the underside of a wooden countertop to protect it from steam coming from door when opened after cleaning?
A couple coats of urethane on the underside of the countertop that's exposed to the steam would do the trick. We installed quartz countertops and used acrylic sealant on the unfinished/unpolished underside just above our dishwasher before installing it.
Cheers, and good luck.
I always wonder how does the rinse aid gets released no one has posted video on that.
There is just a small valve at the bottom of the rinse aid well and when the timer calls for it the valve opens and drains a bit into the basin for use.
Your are wrong!!! Float doesn't trigger the water intake solenoid until water level is reached. GE dishwashers let flow water during 44 seconds before starting the washing cycle. Float is a security that triggers the solenoid ONLY if water level becomes too high.
I'm having problems right now because pressure is to low and 44 seconds of water is not enough to clean the dishes well...
you do not know how all dishwashers operate. Richard is correct.
hello this old house my dish washer main cycle soap door wont latch i would like to know wont i can do to fix this please help thank you.
Maybe...but I believe you are wrong about the Flot, it is not to stop the water normally, it will stop the water only if it overflows, the dishwasher fill at first by time controled by the control panel program
this dishwasher uses the float switch to sense the level. thank you.
That final power drying cycle is wasteful, hence I always choose "no heat dry". Given a couple of hours, the dishes will dry anyway due to residual heat from the wash.
Timur G yep, I just open it up when hot and let the dishes air dry.
Timur G I do the same I pull the door open/pull the baskets out to let it vent properly & the dishes are 100% dry in 10 mins from the heat
The heat is to sanitize
Lol, I friggin got the Gillette add.
2:38
@2:40 going inside
Why does it take hours to do small load of dishes?
I'd buy a dishwasher with a built-in camera that I can watch with my smartphone.
But why?
Whirlpool Corporation makes a dishwasher with a glass window under their KitchenAid brand
@@bonk841 he must be being sarcastic..
the heating element is usually just used on the drying cycle. not to heat the water.
I have never seen a dishwasher with "hot water in" as stated at 0:32 Every single one i've ever installed have been COLD water in ONLY. The dishwasher has a water heater itself to heat the water for its wash cycles.
Game Changer WHAT? Exactly what century was your dishwasher made in? A modern appliance should ONLY have to heat water for a possible sanitary cycle! Yes, hot water in only! You sure don't know how to install a dishwasher! Watch a few installation videos and be surprised!. What an energy waster you are, using a dishwasher to heat cold water, I'll bet your cycles run forever!
love it or leave it, i'm sorry if you're only used to cheap low end dishwashers without a heating system. but EVERY dishwasher i've installed had a heating system. speak of only what you know.
@@randomsecrets you have no idea what you're talking about. all dishwashers require a hot water input. post no more comments please.
i mean what kind of idiot hooks up a dishwasher to cold water. really.
The pump in our dishwasher went out because the last time my mom washed dishes the water did not drain.
So pods = no soap in prewash
that dish washer looks incredibly old
Nope, it's just a basic model. They work MUCH better than the ones with all the buttons.
hello adulthood.
Why am I here....I don’t even own a dishwasher.
wow i though there was a lot more spraying going on inside in different directions. no wonder why dishwashers are crap
I think this one came of of a museum. No comparisation to a modern one. At least the the moderate priced one i bought here in germany two years ago.
32deej There is, that dishwasher has one spray arm. Most regular sized dishwashers have 2-3 spray arms that really increase the amount of spraying going on, but that particular dishwasher is shitty.
This is an example of the kind of trade off with moving to modern appliances. One spray arm but it's still running (what appears to be) 100 years later. But move to a modern one with more features/power and the electronics go south 13 months in leaving you very frustrated and learning how to repair/replace a control panel. This message brought to you by maytag.
32deej I have a newer Maytag Jetclean dishwasher and it works perfectly. I love it!
give it 14 months.
That is a very very old and outdated dishwasher! I hope no one thinks they're like that anymore! They don't have those little water tower things!
they still sell models like this. thank you.
Stop being lazy people. Do your dishes by hand. Its cleaner, less energy, and more satisfying. Plus it also saves time because you can do it quicker than the dishwasher can.
Michael Lim not true. Dishwashers only use a few gallons per wash, whereas the water is constantly running when washing by hand. Also, it takes water of at least 140 degrees to kill all germs, and if you tried to wash your dishes by hand any hotter than 120, it would burn your skin off. In my opinion, it’s easier for me to put everything in the dishwasher after cooking a meal, turn it on at night, and have clean dishes in the morning.
Michael Lim - Dishwasher is more effective. I always did them by hand and liked it. The key it to always have a fully loaded washer so you need more dishes. You fill it up over a few days and run one quick cycle. 4 gals of water is very low usage and id never be able to wash a setting for 8-10 people in that little water
Dishwashers are actually way more efficient than hand washing. Here's one test but there's many others you can google: www.reviewed.com/dishwashers/features/please-stop-hand-washing-your-dishes
Michael R - Hey agreed. However i stopped using the dishwasher in the last month and got a commercial sprayer faucet. The thing i dislike about the dishwasher is that it bathes your dishes in the same dirty water over n over and this requires a strong detergent and a strong rinsing detergent. The Detergents never rinse away fully and over time turn dishes opaque from the strong pitting action. You also drink water and eat food from those plates.
Actually the dishwasher is in my opinion a real time saver as hand wash uses far more water and more energy. It also takes up personal time.
you have realy crappy dishwashers in us......
Milan Dičér this is bad bc it’s for a demonstration
why do you have dishwasher? some people is really lazy doing it.
nobert garcia Or some people have a job and a lot of other stuff to do. No time/energy for manual dishwashing.
Either way, i can still manage to wash the dishes no matter what
said like one person who lives alone and doesn't have much of a life
nobert garcia do you use the stairs to get to the upper floors? or do you climb the building walls? if you use the stairs then you are so lazy.
jrg mty no i fly.
