LG Dishwasher - drain hose replacement

Hello all,
I bought a new LG dishwasher from Home Depot, just installed. I ran a test cycle and found a leak, coming from a cut in the water outlet hose (goes to the disposal). I asked the appliance guy at Home Depot about a replacement hose (which I found can be ordered on the LG website).

Problem is: the Home Depot guy and I spend about 20 minutes with the LG floor model in the store trying to figure out how to get the old hose off. It disappears into the back of the unit with no obvious way to remove it. I'm pretty handy and it baffles me the way they have it designed. Anyone out there with advice?

Many thanks!

    Right on!

    I pulled off the bottom and side panels and was able to remove the old hose. I did a google search for "LG drain hose" ordered the $28 part (I can't believe they charge that much), installed, and ran it. It works perfectly. Thanks!

    I have LG LDF8812ST, drain hose cracked, leaked water into basement ceiling. I guess I will be taking side and bottom off, can I replace with a more substantial hose?

    I had the same cracked hose problem with model ldf6920st. The hose was cracked in 5 spots where it made a gentle 45 degree bend through an access hole in the cabinet to connect to the drain. In only a year the rigid plastic fractured and had been dribbling continually small quantities of water under my cabinets for at least a couple years. I refused to replace the fragile hose with another stock part and risk a recurrence with further damage. In short, I purchased a quality rubber(Made if USA) drain hose kit and re-engineered the hose figment. My cost- $14. Damage done by cut throat quality paper thin plastic drain hose... Hundreds! As an aside, I have a companion LG fancy frig that I invested two evenings to repair the ice maker after a year of use. I don't call service people because I have the technical knowledge to make the repairs. Let's just call these " teachable moments" and move along. No more LG products for this family.

Hello, I have just installed a similar model, and took the side panel off to see how it was put together ;)

The drain hose goes in the back of the dishwasher, then loops up the right side (as you are looking at the front)(this is to act as a "trap" to keep sewer gases from coming back into your washer, I assume), and then connects to the drain pump under the washer.

In order the change the hose, you will need to remove the left side panel, and the bottom panel, and this will give you access to the entire hose....

Hope this helps!

Similar problem: the drain hose went brittle at the sink drain end after just three years and started to leak. This is a design problem, they used a plastic not rated for hot, caustic liquids like dish washer soap. (I work in the plastics industry). Not much faith that the replacement hose will last very long.
It is a bear to replace. Take off left and right side panel (right is to allow water to drain went sideways). Turn onto right side, remove bottom panel. Remove spring clamp from drain hose end (get a real band clamp to replace it). Do the same at the sink end too. Replace hose and reassemble.
I'm going to replace the LG part with a EPDM 5/8" hose.

    I was considering using a better tube as well, but there are two problems. 1) getting all the parts to connect everything properly and 2) finding a back-flow preventor, like the one that's built into the hose. I'm thinking the redesigned parts should be better.

GE Adora dishwasher model ddt575smf0es leaking from condensation

Sounds like a poor install. If the hoses aren't collected correctly heat from water could cause expansion therefore looser doors and hinges. Make sure the water connections are tight and then check the screws at the bottom of the door. you shouldn't need a pro to fix.

Hi! We just installed our LG LDF8812WW built in dishwasher. We ran our first cycle and after the wash cycle the dishwasher displayed error code OE. I read that it meant there is a problem with the...

I actually own an LG LDF8812 myself, except mine is stainless steel, not white. So be it. :-)
Anyway, it sounds like you have just unboxed the unit and it is brand new, not just new to you. I am also assuming that you have this dishwasher connected to an Air Gap valve which is connected to the garbage disposal. Please reply if I am wrong.
Because it is (apparently) new, the first thing I would check is that any water is draining from the unit. A common problem on new installations is that the knockout inside the neck of the garbage disposal unit. A quick way to test that is begin the dishwasher filling, then open the door and press the two buttons that give you Cancel. Hold for three seconds and the DW will begin to drain. Being careful of the hot water that should be draining into the kitchen sink via the disposal, but watch for water to come flowing with a healthy stream - not wimpy.
Please reply with what you have found and correct my assumptions that I got wrong. Good Luck!
OH, if the problem is not something at the end of the drain hose, before you try to crack the unit open (and possibly void your waranty) dial the number on in the user guide and schedule a service call asap. Have your proof of purchase available.

LG will not service the LG 6810 dishwasher

When I have problems with a manufacter customer support line, I firmly but politely contact the agent, explan my problem and request quick resoution. The moment they say they are powerless to act, I imediatly request to be "escalated" to his manager. As soon as I get connected, I reqest dial in contact info directly to the escalation group. If he/she is unhelpful, I firmly and politely request to be escalated to the next higher manager.
In this case, it may be important to work through Home Depot customer service, trying as quickly as posible to get to the group that manages the LG relationship. Home Depot appears to be the organization that supplied the product that is unlabeled. These products are sometime called "Gray market" products.
Anyway, I have a similar LG product that is less than 1 year old. It was working great but all of a sudden it started to not clean well. I found undesolved, moist powder in the dispenser.
What I figured out was that I had switched DW detergent to a generic powder and the poor cleaning problems slowly showed up.
I had these white streaks runnind down from the dispenser on the stainless steel liner, too.
As soon as I switched back to a brand name powder (Electolux or Cascade) and did a white vinegar cleaning by filling a bowl full of white vinegar and placing it on the rack and running a quick cycle without adding detergent, my quiet and cool dishwasher came back!
I learned that these new, water conserving, energy effiecent models need an effective detergent that easily desolves and has minimal 'minerals' included in the powder. I also learned that you should always use a powder, never a gel or tablet.
Try my advice for a week or two. If problems persist, the next most common clearning problem is the heating element is not coming on during the wash.
Give these things a shot and please report back here. Good Luck!

Dishwsher is getting no water?

can you make a test cord out of a short extension cord . cut the cord on the female end and crimp on two alligator clips . now with the dishwasher disconnected from the power grid put the alligator clips on the water valve .check that the alligator clips are not touching nothing but the valve terminals. Now plug up the male end into a wall outlet ,you should have water if not you will know what to test.

I have this same dishwasher,and have had the same problems that have been described in this forum..

LG model#LDS5811.I bought it from Home Depot as a scratch and dent with no warranty available for about $400.00.

The problems I have seen on my own and have read online have been Intermittent leaks on the left side door,as well as both sides.And in some cases,even wiring and motor problems.

In my case,the water was coming from a leaking O-ring behind the evaporator housing in the door,as well as a small hole in the drain hose in the part of the hose on the left side where the hose loops up the side of the machine behind the panel before it comes out of the back.

You will need to take the left side panel off to undo the wire holding the hose in place as well as remove the bottom plate over the motor to gain access to remove the hose from the pump to get the hose off of the machine.Simply replace the hose.You can order online or buy a replacement at an Appliance Repair store as I did.

To repair the door leak,you will need to remove the lower outside panel that is under the control panel.Inside the door,you will need to turn the vent cover at the top of the door counter clock-wise one-forth turn and remove the entire evaporator unit as a whole.You will see a 1.5 inch O-ring.

I repaired this by getting G.E 100% silicone that you can purchase at a Home Repair store like Lowes or Home Depot and sealing around both sides as well as putting a good bead on top of the O-ring itself,and wipe off the excess after re-installing.

I performed these repairs over a month ago,and have had very good success.No leaks to be seen.I am a A\C,Refrigeration Tech by trade,and have done alot of Appliance repair/installation as a side trade from being a maintenance technician at some very large Grocery chains the last 20+ years.

I completely dissassembled this machine and have found it to be a decent product,but some shoddy materials and questionable assembly practices have created these problems,but good sound engineering.

I hope this helps someone with the problems with this machine so it wont be a total loss.

LG Tromm WM0642HW washer leaking water!

I have the same problem - just a small amount of water leaking out from under the machine. I removed the top cover and found one of the water lines rubs on the vent tube and has wore completely through. Should be an easy fix, as the line runs from the #2 spigot on the water inlet to the detergent box - both connections are right on top.

LG Dishwasher model LDF7811 doesn't clean

LG DOES ****. We had this dishwasher and from the very beginning it didn't seem to dry and within a few months it was not cleaning as well as we had hoped. Within 9 months it had gotten so bad that we were really unhappy and then we got an error code. LG arranged for a local repair company to take a look at it. They ended up replacing EVERY part of the dishwasher except the tub itself. They replace the pump, the heater, the whole door assembly, the wiring harness (the wires had started melting into the sound proofing material), the electronics. Literally everything. From that point on we really noticed that we were getting food chunks on everything. Not only that, all the dishes were greasy and it wasn't even coming close to drying. There was mildew and mold growing inside the tub! Finally I got fed up and threw a fit with LG. They sent another repair guy out and he told us it was going to take 3 weeks to get a brand new pump and heater because the replaced heater had failed. After I complained to LG the repair guy got the parts in a week. He quickly replaced it and tested it and it flooded our kitchen (hardwood flooring) and leaked through the floor to the ceiling downstairs. The new heater was faulty. Not only that, the repair guy told us that the first repair, 9 months earlier, had not been completed and our turbulence detector had never been hooked up. Our solution? We fought with LG and Home Depot, where we got it, and LG offered to replace it with a new dishwasher. I said forget it, we didn't ever want an LG dishwasher again. Home Depot stepped up and took back our 2 year old dishwasher and refunded all our money. We bought a KitchenAid and we LOVE IT!

Dishwasher will fill and drain, but will not cycle!

Bobalou If you just bought and installed, I'm assuming you dish washer is brand new. It means it has full warranty with Maytag. Do not do anything. It will void your warranty. Call Maytag authorized service. back
