Thank you so much for all your videos, and for your patient, detailed answers in the comments section. I have the same LG set, and didn't really know how to repair the flow code, so I clicked on ur Amazon link and purchased the vent cleaning tool. It should be here in a few days, so I'm super excited to get cleaning and stop that code from coming up. I'm also glad you showed how you stacked your units because I actually started doing that with mine to make better use of my laundry room. Definitely subscribed, keep up the good work!!!

This was VERY HELPFUL... and will save us a ton of money . Thanks soooo much.

[@truthlove1114]

The exact video I needed to watch. Thanks for posting this!

[@girishm3864]

Good informative video with precise information.

[@luxuryfam1284]

Thank you so much for your video. I just got new dryer and it keeps shutting down and giving me the same code. Time to unclog the dryer vent… this is going to be a beautiful mess… appreciate it Brotha.

[@agratefulheart512]

This is all great information in my opinion.

Thank you for doing this video.

Thank you so much!

[@samcat2000]

Thanks for this video. Before purchasing the tool I need to figure out where my dryer vent exits my house. I’m a new homeowner and have lived in this home less than a year. Bought a new LG set and keep getting the d90 code. If the vent exits on the roof I’m going to have to get someone braver than me - meaning a professional - to get up there to clean the vent on the exterior side 😳.

[@DIYAroundTheHome]

The next time it's cold outside and you run your dryer, walk around the outside of your house and look for the vent. It'll look like the "stream/smoke" exiting your mouth when you exale through your mouth outside on a cold day

[@danheuser5148]

I did a duct cleaning like this and was still getting the D80 code (including vacuuming out the lint filter area), so I tried washing the lint filter. The filter didn't look unusually dirty, but maybe the tiny holes were all just a little too plugged up. I haven't had the D80 error since. So either it was a fluke or that was part of the issue.

[@Ramos51010]

I just installed a new LG DLE3900 and used new dryer vent tubing. Got the d80 immediately. From inside laundry room I looked up inside the outside vent tube that runs up to roof and saw nothing major. I am going to go up onto the roof and check next.

[@Ramos51010]

I have a new construction home maybe 4 years old now. Would there be a lint/debris obstruction already? I haven't cleaned it out since we moved in.

[@DIYAroundTheHome]

Could be for sure.

[@anthonyross3957]

Excellent video. Just got the dryer and having this error continuously. Can I ask what kind of vent hose you are using? Flex?

[@DIYAroundTheHome]

I have solid metal ducting all the way. I removed the flexible venting (a short 90 degree segment) when I stacked my dryer on top of the washer. You can see that video on my channel too.

[@jbright97]

did you cut the dryer vent hood outside to fit the leaf blower? I notice no shot of laundry room after leaf blower, mus have been a wreck. leaf blower inside the house blowing outside would have worked better. that what we did. but hey good video

[@DIYAroundTheHome]

I cut the hood in an effort to help get the cleaning tool out, it was stuck for a bit. As for the leaf blower I didn't do the best job showing everything I did with it. For example when I showed blowing INTO the house I didn't show footage of my wife with a garbage bag on the other end of the vent. She loosely wrapped the opening of the bag around the duct to catch junk and keep the mess down inside the laundry room. Also I didn't show footage of us blowing from the inside out either which was easier for sure.

[@tonywoo9435]

Nice video. But I can not entny the test mode with pressing that button. I am pretty sure we have the same model dryer. any suggestions? Thx

[@DIYAroundTheHome]

I had to try it several times to make it work... it is not super straight forward. If I recall correctly I think I found a KZbin video too where someone showed how they did it... so maybe look on YT for a visual on how to do it? Good luck!

[@tonywoo9435]

@@DIYAroundTheHome Thank you. I just tried couple times, then it works. Thank you sharing this experience.

[@mattrojanakiathavorn6020]

Just had a full vent cleaning prior to having a new LG dryer delivered, and got the d80 code on the first use. Pulled the vent off the back of the dryer and put it back on and then got a d90 code. Any thoughts on what might be causing it?

[@DIYAroundTheHome]

Hmmm, new machine means it's the ductwork. How far away is the outlet vent to the outside of your home from the machine? How many 90 degree bends?

[@mattrojanakiathavorn6020]

@@DIYAroundTheHome there’s one bend out the back of the machine and then one into the wall. The machine is on the first floor and the outlet is out the roof on the second floor

[@DIYAroundTheHome]

See if you can measure the distance (roughly) and count the number of 90 degree bends then see if you are within spec by looking at the end of your product manual. In mine it lists what are acceptable combos.

[@sivakonka9405]

Hey can you recommend the dryer duct for new lg dryer? I am getting d90 error after 5-10 min of starting the dryer. Mine is a new home and what could be the problem?

[@DIYAroundTheHome]

It shouldn't be the case but the builder could have made too many turns in the ductwork or the ductwork could be run too long of a length. If you look at the user manual for your dryer it should have details on how many 90° bends and how long of length the line should be. I try and find where the exhaust comes out of the house and then see if you can measure it. Also try to remove blockages from the inside ductwork and then from the outside. Hopefully you can get far enough back that you can get it on both sides. Maybe some construction worker put something in the duct work? Shouldn't be lint if no one's lived in it

[@sivakonka9405]

@@DIYAroundTheHome thank you so much for the quick reply, my dryer duct is second one in your pic obviously not the best can you recommend me anything that I can purchase on Amazon?

[@DIYAroundTheHome]

@@sivakonka9405 the ideal duct is straight/flat metal (not ribbed). There are no brands that make anything different than another so it really is a matter of looking at your set up and decide if you need two 90° bends and a straight section (4" duct work is normal size) or some other setup

[@Reed_steven]

Are dryer is throwing the flow sense light, but our house is just built and everything is new. And we never had that night at our rental house, it’s the same dryer

[@DIYAroundTheHome]

Look at the lint screen in your actual dryer. Pull it out and clean it along with the space where it slides into. You probably have a lot of lint stuck in there

[@Reed_steven]

@@DIYAroundTheHome the dryer screen is cleaned out, and I’ve taken off the dryer duct tube and clean it out as well. Still didn’t fix it.

[@DIYAroundTheHome]

If it isn't the machine I would have to think it would be the ductwork. Maybe some construction worker stuck garbage in it. Wouldn't shock me. When I regraded and installed an irrigation system in my front yard this last year I found bottles and soda cans and other trash 6 inches deep in the dirt... I ripped open a section of drywall a couple months ago when I had a leak and there were a couple empty cans of Coke in the wall. Sometimes these construction workers get lazy and just throw garbage in the stupidest places. Maybe your duct work is filled with similar crap?

[@Reed_steven]

@@DIYAroundTheHome I’ll take an air blowing the the pipe that leads into the wall tonight

[@TMS5100]

I ran a brush connected to a power drill all the way through the duct and barely any lint came out. Unplugged the dryer for an hour, completely disconnected the hose from my LG and ran the test and it still throws a flowsense error. That should totally eliminate any possibility of duct issues, so what do I do now?

[@DIYAroundTheHome]

Try cleaning out the lint under the lint trap. Open the front door and pull out the lint trap then look under it Use needle nose pliers or forceps to pull out the lint. Kind of a long shot but worth trying

[@TMS5100]

@@DIYAroundTheHome lint trap and everything inside is clean as a whistle. what next?

[@DIYAroundTheHome]

This page linked below says you should test with wet clothes. Maybe try that next? www.lg.com/ca_en/support/product-help/CT20098071-1417122570588-error-codes

[@brooklynboi11207]

I did the same, then I removed the vent to test it and still got flow sense error. Could the sensor be bad?

[@DIYAroundTheHome]

That could be the case for sure

[@yeeericm60]

Curious how long you had gone between duct cleanings to accumulate that volume of lint. (I’m coming up on my first anniversary and plan to have the duct cleaned professionally once before I try to do it myself.)

[@DIYAroundTheHome]

That's a good question because we moved into the house not super long before doing this video... so we really have no clue when it was last done because the previous owner didn't leave us any details on maintenance

[@yeeericm60]

@@DIYAroundTheHome Thanks for your prompt response!

[@JamesMooreSeattle]

Before you do anything, just physically disconnect things and take a look. Sometimes it's completely obvious how easy it is (or vice versa) if the vent runs are short.

[@MrFailautusi]

I did all the cleaning and checking for dryer vent and still have the D90 code pop up. What else can I do?

[@DIYAroundTheHome]

Did you clean the lint screen and underneath the screen that pulls out? A lot of junk can get trapped down there

[@danheuser5148]

Washing my lint screen seemed to help solve my D80 error code. Maybe the little holes gradually get a bit too plugged.

[@tommyg5729]

i put a shop vac outside and my cordless leafblower in vent behind dryer, lots of lint but my run is 40 feet, cant believe that it is code

[@DIYAroundTheHome]

Does it have a lot of 90s?

[@tommyg5729]

@@DIYAroundTheHome one 90 as it goes into basement and one 90 6 ft before exit, makes zero sense. just got new dryer 2 weeks ago, its working but have to use low heat. going to try using a roto rooter , hand held one for plumbing in both ends and use vacum and blower again. dont know why they did it that way, high end house 20 years old. If that doesnt work going to have to disassemble duct work which will be a royal pain. thanks for replying

[@mrpaudir8444]

Silly but how do I find my external dryer vent? It's not obvious at my home

[@DIYAroundTheHome]

If it's cold out you could put a load in the dryer and turn it on and look for exhaust escaping the house. It's either on the side of your home or on your roof. In my case I have a flap that closes the outlet when nothing is being exhausted... When I turn on my dryer and air starts coming out the flap lifts up. That's how I identified it

[@yanshanye]

D90 code ? Please

[@josephlamb87]

Just got the washtower the dryer will not staying on

[@TECHIELIFE]

Same.

[@boorayin2773]

You should have included the shot where you blew a bunch of dust all over the washroom with the leaf blower and the verbal grief that you got from your partner! You shoulda blown from the inside, instead! :)

[@DIYAroundTheHome]

She actually had a large empty garbage bag wrapped around the ductwork so it blew a bunch of dirty air into her garbage bag. It did get the room a little dusty though. We blew it from both directions also by the way
