Holy crap !! After being told it was the dishwasher pump and a faulty garburator and both needed replacing. I cleaned out the bottom of the dishwasher then took the hose from the dishwasher to the garburator off and put it in a bucket to make sure the dishwasher was draining properly. It was working fine, so I then took your video advice and raised the hose then re-attached it to the garburator and guess what ? That was the only problem. Everything works fine now. It was so simple. Thanks Grumpy man.
I always appreciate a simple, and to the point, demonstration.
Using a simple rerouting hose. Brilliant I can’t believe I did not think of that. I’m telling my wife I did that will give me some brownies points. Bravo sir.
I did it like you showed & it saved my kitchen from the stench I used to have in the dishwasher that i don't use. Thank you from the bottom of my heart, dear Grumpy man!
Had this issue with my dishwasher , figured it out by myself but came here looking for a confirmation. Thanks a lot for sharing
Great call - I hadnt thought of that at all. havent had any issues sense. But anecdotally the same is true for how you run your water pump to a water cooled PC. never even thought about to apply the same principle but it makes perfect sense.
THANK YOU!!!! You saved my bacon! Our dishwasher has smelled awefull since have a new disposal installed, months ago!!!
Need to be more grumpy! He was my favorite dwarf! My four kids favorite also!
Thank you!! Solved this problem all by myself after watching your video and my family full of contractors are very impressed 🤣
I've had to watch about 5 or 6 other videos before I got my question answered. Thanks. You didn't really speak the answer but your diagram showed me what I wondered about. The air gap hose. I was going crazy trying to see how to run it. Now I can see that I have about 3 feet more than I need. The hose comes into the cabinet from the dishwasher. It enters at the top of the cabinet, but of course the hose comes from the bottom of the dishwasher. So all I need to do is just have enough of the hose to go from where it enters the under sink cabinet to the air gap. Thank you.
I had the same problem and i was able to lift the hose and tape it to the bottom of my sink and it actually worked!! I was able to see some dark water in the hose right where the water used to back up. Thank you for the video!
Glad I could help!
@@TheGrumpyPlumber this quick tip is still paying dividends! It didn't look like I had enough line to bend it upward, but a few tugs and I was able to get another foot or so; enough for a good upward loop! God bless your grumpy plumbing heart, Good Sir!
Mike
Wow!!! I have been scratching my head for three weeks trying to figure this out. This started back then and I cleaned the inside of the dishwasher like I have seen on 100 different videos. Then I checked my drain lines for any clogs. When I hook the lines back up I didn’t have it high enough and it was backfilling from the sink. Thank you so much.
Thank you so much Mr. Jim I cannot figures it out until I found you
My dishwasher backs up and smells horrific! Going to try your suggestion this weekend and let you know how it goes. Thank you Grumpy Man and 🤞
Yes I’m having the same exact issue! How did you end up fixing it?
@@XxJoejohnsonxXugh they never come back to report!
😆 I'm laughing because it's so true. That's why I usually just say thank you and try it at some unplanned time
So how’d it go?
Thank you for showing us that. You're the best
🤣🤣🤣😍😍😍 the grumpy plumber!!
Okay, I just tried it and when my dishwasher finishes this rinse cycle I will try to finish the rest of the dishes and see how it goes. ❤❤ THANK YOU
Just FYI it worked so good. My dishes are coming out of the washer dry and the washer isn't filling with nasty water when I do things in the sink
Love it! Short and to the point, and best of all, it works!
Thanks, been driving me bats, was sure it was from the disposal unit and was going install a check valve on the connection side, I'm more than happy to have found this simple solution!😁
2 handyman’s visits, 1 plumber visit and few phone calls to LG customer service. None of them was able to figure this out. They all said:
1: I have no idea whats the issue
2: buy a new dishwasher
Until I found this video like 3 weeks ago.
Used my dishwasher for more than 10 times since then and BOOM the AE error is gone so as the flood.
Thank you sir 🙏
Hey thanks, this was a huge help! Thank you for the quick simple explanation.
Omg your genius! Thank you for sharing this!
Wow, simple physic; I have had that problem and was scratching my head. Thank you!
thanks big help my roommate acts like he knows everything but aperently he couldn't even do this, there is even a hose clamp already down there
Brilliant. I just did this. Appreciate the simple fix.
I've been having this issue in my brand new house. I just moved the hose fingers crossed that it works!
Yeah I kept having this problem, hope this will do the trick,Thanks
Thank you, sir!
I'm having this same problem and by the way!
Your not grumpy at all!😉🙏
There’s nothing grumpy about him. 🤔🤣😂
@@dakmycat3688
Thanks and I just wanted to let him know that I did what he said, by placing the draining hose higher and it worked!👋
I also called a plumber and I had a handyman try to fix it first and neither of them knew how to fix it but I fixed it myself with the help from this video!
So, Thanks, again!✌️
Attach the drain hose with a wire tie or clamp so it does not fall down From a Maytag repairman who is not lonely!!!
Hi! If I want to permanently remove the dishwasher, do I need to seal where the hose would attach to the disposal?
THANK YOU! I just got done cleaning up water that spewed all over my counter top 🤦🏻♀️ I’m not handy but I was able to fix this!
I started the video as a child. Now I'm a MAN! THANK YOU SIR!
Thank you for saving my kids' college funds! I called someone and he wanted to charge me $200 just to come take a look and at the end, he will probably just do what you did within 5 mins.
Thank you Sir! Quick and simple
Fantastic! Thanks! Perfect visual.
Very helpful !!!
Damn it, this fixed my problem! Geeze... Thanks a lot!!!!!!
Thanks for this!! I’m all sorted.
Grumpy plumber, if you don’t mind asking you, today I poured out left over laundry detergent to recycle it and washed it out a tiny bit in the sink which I’ve never done before. A lot came out as you can imagine and I cleaned my sink after and thought nothing of it and recycled it. However I was running my dishwasher at the time and didn’t even think about it and I’m paranoid that somehow I could really hurt myself by using my now clean dishes. I know I’m just being paranoid and there were/are no clogs at either end, was just hoping you could reassure me.
This is so smart. THANK YOU.
You’re fucking kidding me right? the definition of an easy fix. Thanks!
😅😅 simple video and short, thank you 👌
awesome video !
You are the best.
amazing trick thank you sir :) good job
You're the best!
Thank you Sir 🫡
Thank you. Your solution fixed the problem!
What about the food debris from the disposal staying in the corrugated dishwasher drain house? With the little bit horizontal before it curves up doesn't drain out all the way with the corrugation tubing. I wish the was a diagonal boot connector & non-corrugated hose that could be used.
You only use a corrugated drain pipe at the last resort. When you buy a new garbage disposal a 90degree drain elbow comes with it. The only time you use the elbow is when you have a single compartment sink. If you have a two compartment sink, they make a disposal kit that comes with a 12” pipe with a flange on one end and a baffle tee. The trap will go on the bottom of the baffle tee that is connected to the basket strainer. That’s the proper way to do it. Some states or cities require a trap for the disposal and a trap for the basket strainer. I always use a disposal kit on a double sink.
What about the opposite,water from my sink comes out of the dishwasher, how can i fix that?
I want to eliminate the counter air gap, but I'm concerned that a clog in the line from the dishwasher to the disposal will send dirty water back into the dishwasher. Anyway to safeguard that from happening?
Take the drain hose and run it up as high as you can underneath the sink and then connect it to the garbage disposal. Water can’t run back into the dishwasher with this method. Do not use a check valve as they plug.
Yep. Just worked for me. Thanks Grumpy!
My new garbage disposal doesn’t seem to drain as well as the old one. Noticed it multiple times and usually I just turn it on for a second and the water drains away.
Today as I’m rinsing my hands and the sink is full of dirty dishes I notice a dripping noise. Turns out my dishwasher, door open, is leaking water on the ground.
My washer drain hose usually almost touches the bottom of the cabinet.
I guessed water had been backing up into my dishwasher. So I lift it up higher and see you did the same thing.
But I came to TH-cam to see why the disposal isn’t draining regular water.
When I buy a garbage disposal, I only purchase InSinkErator brand. If I bought one that wasn’t draining properly and installed the drain correctly , I would take it back and get another one.
Wow that actually worked 🤣🤣🤣🤣🙏🏾🙏🏾🙏🏾🙏🏾 you’re the best champ
Thank you! Will this help fix food particles from being deposited during the rinse cycle?
RodeoRamsey, my recommendation is to clean off your dishes before putting in dishwasher. If you have a loop in the drain line, you shouldn’t get food particles back through the drain.
Brilliant!
Thanks so much for your videos. My problem is that water is coming out from the bottom door area & fr what appears to be behind my dishwasher. I’ve cleaned all filters. Any suggestions?
Teresa Fortner Ballentine, have you checked the water connection in the front under the dishwasher? If so, and it’s not leaking from there, it’s time to buy a new dishwasher.
Thank you so much, I think that's what I have to do!!! 😊
Thanks!
soda neutralizes acid, I would advise to put soda in the oven for 30 minutes and then the soda becomes soluble and very strong
This helped me! Thank you.
Thanks for the video. Any thoughts on a very slow drip at the dishwasher drain connection to the disposer? I recently replaced the drain hose from the dishwasher with a new LG part and bought a new clamp like the one in the video. Seems no matter how tight the clamp is there is still a very slow leak on the bottom of the connection. Should I wrap the disposer flange in pipe tape before making the connection and clamping?
Mark Lalumia, you might have a crack in the connection coming out of the disposal. If so, you’ll have to replace the disposal.
@@TheGrumpyPlumber thanks for the fast reply. I'll have to really examine it closely...it is a pretty old insinkerator so totally possible.
Waiting now to see if my problem is that simple… 😳😁
It’s backed up a few times in me… pulled it out took off the hose… cleaned the INSIDE… checked the sing drain trap… took IT apart… checked the disposal… and was just about to call the service man…
So far so good! What a simple fix that makes sense… THANK YOU (so far 😉)
SADLY… this DID NOT work for me….😢
I thought for sure it would work… 🤷🏻♂️
What the heck else can it be!? 😡
Jim Powers, so you took the dishwasher hose and raised it way above the inlet connection of the garbage disposal? If you did that, I think the problem is with your dishwasher not draining properly. If the dishwasher is over 5-6 years old, I would put the cost of a service call toward a new dishwasher.
Hahaha trying to tighten screws like that with a flathead always sucks😂 always use my 1/4 or 5/16 end on my screwdriver whenever i can😂
Worked for me. Thanks
I found out I had the same problem today. Figured out why it was happening and came here to find it is a really common problem. Disappointed you are not grumpier.
Can this be done with water in the sink or no?
@@thegoldenonezz you want to drain the water out of the sink before working on it.
Thankkkkkkkk u appreciate i tough my dishwasher was broken
I live in an Apartment, ever since we moved in the dishwasher when we aren’t even using it has water coming out inside it and it’s dirty water. I don’t know if it’s from the bathroom or sink. Would this solve that issue ? They’ve replaced the dishwasher and it does the same thing so I’m assuming it’s a plumbing issue
Rebecca, Cervantes, check to see if the dishwasher hose is higher than the garbage disposal connection. What I mean by that is, you want the hose to come out of the disposal and go up to the bottom of the countertop inside the cabinet and then down to the floor and then into the dishwasher cabinet. That stops the dirty water from the kitchen sink from running back into the dishwasher.
@@TheGrumpyPlumber if it’s too short am I able to buy an extension of that hose ?
Rebecca Cervantes, yes, you can buy a 5/8” inside diameter rubber hose and some stainless steel clamps ( one for each end). Also check if there is extra hose under the dishwasher. Pull on the hose from the inside of the kitchen cabinet. If there is extra hose there, it should come out. If there is a check valve at the garbage disposal and where the dishwasher hose connects, you don’t have to remove it. Just tie the hose as high as you can up near the bottom of the kitchen countertop.
@@TheGrumpyPlumber you are a life saver thank you so much !
I feel like an idiot after watching this. lol. Thanks for an easy solution.
Shouldn't you secure the drain hose to the underside of the sink so that when the diswasher empties, it won't sag?
You want to secure the drain hose to either the bottom of the counter top or the back wall of the cabinet as high as possible. The high you get the hose, the less chance of water draining back into the dishwasher.
Too funny, Ty for the info
Perfect!
My hose is connected to the bottom corner not the top like yours how do you fix it like that ?
You usually have about 6-8 feet of drain hose on a dishwasher. It’s easy to make a loop by pulling the hose up to the bottom of the countertop and then down to the garage disposal drain.
If you don’t have much hose, then add 7/8” ID hose.
Why use different type pipe before and after air gap
Why use an air gap? It’s just as easy to take the drain hose on the dishwasher and take it up to the top of the cabinet side of the dishwasher and down to the garage disposal. Or, if you bring it in through the bottom side of the cabinet, take it up as high as you can and then bring it down to the garbage disposal or branch tail piece. Your better dishwashers like Bosch or Miele don’t require an air gap but I always run the drain up high. To answer your question, I don’t know why they use 7/8 on the inlet side and 5/8 on the outlet side. I do know that they are nothing but a pain in the you know what. Most plumbers will install them and remove them and install some other fixture in their place. You put a loop in the drain to keep the water from running back into the dishwasher.
Can I plug up that hose connection coming off the disposal? Because I don’t use the dishwasher and connection coming off disposal leaking sticky oil 🤢.. if so what connection size ?
NO FREE RIDES!!! Get a 4” long 7/8” inside diameter hose. Get a 3/4” copper cap and 2 stainless steel hose clamps that will fit over the disposal connection and 3/4” copper cap which you will insert in the hose and clamp them. The hose clamp should be around 1 1/4” in diameter.
@@TheGrumpyPlumber great .. thanks
My dishwasher drains fine and the discharge hose is high in the cabinet under the sink. However, water from the sink/garbage disposal seems to seep back into the dishwasher when the sink backs up or the garbage disposal turns on. Can I install a back flow valve in the discharge line to prevent this from happening?
George Longyear, you want that drain hose to be touching the bottom of the countertop under the sink if at all possible. You shouldn’t get water back from the garbage disposal if the drain is as high as you can get it, at least five inches from the bottom of the sink bowl. You can put a swing check valve at the inlet where the dishwasher connects to the garbage disposal or put an air gap in your countertop and connect the dishwasher line to that. But if that hose is high enough, you shouldn’t have that problem unless you really fill your sink up with water.
@@TheGrumpyPlumber Thanks for the quick reply. Yes the discharge hose is at the top of the cabinet at the counter top, but we still get backup, Thanks for responding
George Longyear, are you sure it’s not the dishwasher pump not pumping out the water completely?
@@TheGrumpyPlumber After we run the dishwasher the drain is dry. We only use the dishwasher on occasion, so when we do go to use it, there is water in the drain that smells
George Longyear, add a check valve at the disposal drain inlet.
my samsung dishwasher goes thru the complete cycle find but then fills with water several hours after it was dry inside. if i just run the drain function it drains fine. i cant find a leak. the drain hose high loops looks fine its around 18 inches off the ground under t he sink and i klnow it isnt pinched. any ideas?>
Thank you!!!
Surprising in my city I did not pass inspection wen I put the dishwasher drain in the disposal
Victor, your inspector probably doesn’t know there is a built in air gap in the dishwasher. And they don’t want to update the code.
I wonder if anyone could answer my question 🙏 my sinks drain really slow, water backs up..then water from the sinks seem to overflow to dishwasher and water in the dishwasher overflows..
I tried to use draino several times, used snake cable through the sink pipes… still the same problem.. what could be the problem?
M P, p-traps on plumbing fixtures only plug on TV. Those drain cleaners you see advertised on TV don’t do anything. Get a reputable drain cleaning company and have them remove the drains under the sink. Clean the drain where it goes through the wall. If it drains slowly now, they should be able to open it up. P.S. if they walk in and ask you to sign a service contract, ask them to leave.
Thats the reason ive been grumpy my whole life, i did this and what do you know? Im no longer the grumpy wanna be plumber i once was
I may be misinformed, but I'm in California and I was told doing it without an air gap is against code. (Personally, I don't care so I use the hole for a soap dispenser.)
Is that true, and if so, WHY?
Charlie Horse, plumbing inspectors get a commission for making sure there are air gaps. Just kidding. Nowadays, good dishwashers have a built in trap so you don’t need an air gap. Good quality manufacturers don’t want you to use an air gap. A lot of times, air gaps are there but not hooked up. Definitely do not use a check valve in the drain for the dishwasher. I have a CA plumbing license.
@@TheGrumpyPlumber Now that I think of it, it wasn't plumbers who told me this, but the contractors who installed our granite countertops. Without telling me, they drilled a hole for the "required" air gap. I wasn't sure about the code (and I'm still not) but I knew it wasn't necessary so I replaced it with an air switch for the disposal.
It kinda pissed me off when they cut the hole without checking with me, but ah... "code". As a customer, I couldn't argue with code, cuz... it's CODE.
Just installed my first dishwasher no leaks but when i plugged everything back into the wall the garbage disposal turned on automatically and wont turn off🤷
A garbage disposal can be on a wall switch or an air switch. When it’s on an air switch, it’s plugged into a box that turns on when you push the button.
Life saver!!
How to fix back flow from garbage disposal to sink ?
@samafsahi, is there a baffle tee that connects the sink drain to the garbage disposal drain? If you don’t have this tee, that causes the backup in the sink when the disposal is running. That is an easy fix, less than $10.00. If your kitchen sink drain is draining slow, that could cause a backup. I think it’s the baffle tee.
I did this, And it still isn’t draining. I have no air gap. Thoughts?
Did you clean out your trap and drain?
Quick and easy.
I don’t have anything to put the hose high up on the way the plumber did mines
Plumber keep saying it’s fine but water backs in dishwasher and runs to dinning room.What else can I do?
Betty, make the hose longer so you can raise to the bottom of the countertop and then into the garbage disposal or the drain. ( You can add at least three feet to the hose and that should work).
Thanks uncle Ben 😢
Just looked at my hose under the sink and that thing is probably 4 feet long and all loosey-goosey !
ahhotep8, tie about 2 ft. of the hose as high up as you can get it under the countertop.
@@TheGrumpyPlumber Will do ASAP! Thank you!!
