What People Are Saying

Rated 3 out of 5 by from Defective drain tubing--replaced and began leaking Not too long after my initial purchase the drain hose began a torrential leaking during the drying cycle. I had a warranty and it was replaced. Now the replacement is leaking in the exact same spot. Obviously, this is a part defect. Other than that I love this machine.

Rated 1 out of 5 by from dryer quit working and can't be fixed! I bought this combo washer/dryer only four years ago. It has had to be serviced twice. Now the drying cycle makes the clothes sopping wet and the repair service can not figure out how to fix it! A lot of money spent on a short-lived appliance!

Rated 1 out of 5 by from Motor been replaced annually About 12 months after purchase the machine motor stopped. Had it repaired, and had to pay the full price since the 12 mo warranty had just expired. At the 24 mo anniversary again the motor went out. Again had to pay full price for the repair. Now the motherboard is out. [This review was collected as part of a promotion.]

Rated 5 out of 5 by from I love my washer/dryer combo I bought my Front Loading Combo, July of 2013. My machine is ventless, something I thought would be pretty good. I haven't had any problems with my machine. I love it. [This review was collected as part of a promotion.]

Rated 5 out of 5 by from Purchased in 2012 and am delighted with all the features. Had some trouble at first figuring out the "Spinsense" but it works beautifully on wooden floors.

Rated 1 out of 5 by from Stay away! Three repairs in three years This washer/dryed worked perfect for the first two years but from then on it seems to break down every couple of months. First the drain hose ($40 for a hose) started leaking due to the poor restraint design. Then the drain pump stopped working as well as few months later (~$50). Now not barely a month after that the washer wont turn on so it is likely either the display board (~$80) or the main control board ($150)...I am a Mechanical Engineer so I can make the repairs myself, but if I wasnt able to then I would have had to shell more than the washer is worth on repairs already. Do yourself a favor and do not buy this!

Rated 1 out of 5 by from Second Time this Model Stopped Working This is my second model of this washer/dryer combo unit. The first was one that I "adopted" when buying my condo and I believe it was 5-7 years old. The problem was related to it no longer draining. Despite checking hoses, pulling it apart, etc AND having an authorized LG repair person come to diagnose. After this frustration I decided to buy new. I hoped to get a new model and brand due to this issue and because it takes HOURS to dry. Unfortunately, it turned out the only alternatives that would fit in my small condo consisted of a very tiny washer and dryer bin capacity size (due to the vent hose clearance needed - where this unit is ventless). So I thought I would take my chances. After 25 months, I am back with the same problem I experienced with the first. No longer draining, at all. I have to manually drain it from a front tube which is a various laborious process. I do NOT recommend this product. I did maintain and clean as recommended. I do not have hard water or build up. I performed regular tub cleanings and wiped around the rubber sealants to get any lint left behind after washes. Yet still, it is no longer usable.
